This data will be useful in finding a new capacitor, especially as you can show it to an employee at the store and have them help you find a new capacitor with the same characteristics. Before taking out the old capacitor completely and buying a new capacitor, take a picture of the old capacitor in its place. This is important as connecting them incorrectly may lead to electrical accidents or the breakdown of your air conditioner. First, disconnect all wires from the ruined capacitor.
Then, using the picture of the old capacitor still connected to its wires, install the new aircon capacitor and connect all wires to its respective spots. You can also disconnect one wire from the old capacitor, then connect it to the new capacitor, before going for the next wire.
As a final step, turn on the condenser. Switch on the thermostat and start up the air conditioner. If everything is working alright and you no longer hear the humming noise, you can start using your air conditioner regularly again.
Hopefully, this information has saved you your air conditioner and money from maintenance costs. To prolong the lifespan of your air conditioner, make sure to protect the capacitor through responsible air conditioner usage and regular maintenance. Especially in hotter climates, your air conditioner is working twice as hard to keep the room cool. When forced to work all year round, the capacitor takes a blow from the constant overwork. Thus, use your air conditioner responsibly! Make use of the aircon dry mode that uses less power, or keep the unit off during chillier nights.
You can also switch off the unit completely once the room reaches your desired temperature, as the room will stay cool without the air conditioner unless you have multiple windows open.
Have a professional check your unit every quarter and have it chemically cleaned annually. This will keep all the components in your unit running optimally and prolong the lifespan of your AC. Our highly-skilled AC technicians will ensure your air conditioner stays as good as new for as long as it's yours. Visual symptoms As a capacitor degrades it will have a bulged appearance, with the normally flat top becoming domed.
Bulged capacitor Good capacitor Necessary safety precautions Many HVAC capacitors are designed to provide high voltages when fully charged, so improper handling can cause electrical shock. When replacing a capacitor there are several safety rules you should follow: Never ever touch capacitor terminals. Never short the terminals with a metal object. This can create heavy sparking that can cause a fire under the right conditions Discharging should be through a resistance load by a specialist.
Steps for replacing a capacitor Replacing a bad capacitor before it damages the motor it powers is essential. Remove power disconnect or turn off power to the AC. Remove the access panel. Note the make and model of AC equipment to ensure you acquire the right replacement. If you replace the capacitor with one that has a lower voltage rating, excessive strain will be placed on the capacitor significantly shortening its lifespan.
Discharge and dismount the old capacitor. I have not been able to find anybody, including Carrier technical support, who can tell me the specs for the original capacitor.
Anthony - You may want to check out the contactor. I see your other question about pushing with a stick as well and if you're hearing clicking and the stick trick didn't help you diagnose, it may be the contactor is weak or fried and not allowing power to the unit.
The clicking may be it attempting to connect but not quite getting it. Perhaps this will help you make that determination. Hey I have a problem with my ac I have a heat pump. The problem is when the ac stars the fan that go outside works but the fan that blows air to the house trough the air vents not working. But sometimes it works this is killing me. That means sometimes work and sometimes it work..
Theresa - I'm really not sure if you have an issue or not. All I can say is it's been a very hot summer where I am and so is mine. Perhaps the insulation, doors, windows, etc This is very common but again, you are not alone if you're having the kind of summer I am.
Jane - I'm really not sure what a code 89 is but Honeywell does have a tech support hotline and website. You can only do this for about minutes at a time with breaks in between.
Maybe keep a separate temperature gauge near so you know what the temp is. This makes you the thermostat and if you forget to do the thermostats job you could damage your whole system. Leyotuar - There would be a lot of possibilities. If you lost power then it's possible there was a surge when it kicked back on and that can sometimes take out more than one component or affect it's performance at least. You might want to have a tech check this out for you because there could be a situation where one part gets replaced and reveals another issue making it very hard for me to offer any sound advice.
Hi Dan-I went out of town and turned my unit up to When I returned I have little to no air flow from my vents. My kids told me there were several pretty nasty t storms though the week. I have the same amount of air flow on cool and heat settings. When I turn unit off then back on all I hear is a click sound coming from the outside unit. I tried to spin fan blade and nothing.
My AC honeywell thormsta has error code And we can't turn on the AC system. What is the problem? My AC unit seems to run most of the time even when it reads the proper temperature on the thermostat it still seems to run I have changed The thermostat twice and both times it seems to do the same thing any helpers. Kaelynn - While I can't say for sure what's happening you may want to consider the contactor as a suspect.
If the contacts are charred or the coil in it is going bad perhaps it's not getting a good connection and causing it to be intermittent while the indoor unit is unaffected. Our AC unit was working fine until our outside fan stopped working one day last week.
My husband got it to go by starting it manually with a long screw driver. We thought we were good. A few days later it happened again. We replaced the capacitor. The fan now works intermittently Then I turn it off and leave it off for a while. It usually starts back up. Could the new capacitor be bad? Could it be something else?
And we are not getting very good output of air from our vents. Is there something inside we need to replace? A different capacitor? We have cleaned the inside and outside coils. Nothing Ian freezing up with ice. And the outside unit was super hot when I turned all started. Mary Lou - You would need to know they put in the right capacitor and installed it properly. If so, then I can't see that being any cause of that.
Perhaps a lightning strike? Any signs of that? A power surge can sometimes cause damage as well when power goes out and is restored. I had a capacitor replaced on a Monday evening after my 6 year old AC unit with a 5 year warranty was not blowing any cold air. The AC worked until Saturday evening around P. There also happened to be a bad storm going on at the same time. I called my utility company on weekends you do not get a live person and also tried to switch my house main electric several times,but no power.
By Monday it was determined that the AC blew out the power and also that now the compressor was also bad , I was now informed I needed a new AC unit. My question is , the technician that came initially said the compressor was OK on Monday and by Saturday was bad, was the installation of the capacitor the possible cause of the compressor being blown on a 6 year old unit?
And if so, how do I prove it to the company that did the repair? Maureen - That's really up to you but since they are only a few dollars perhaps you can keep one on hand in case it does go. Preventative maintenance is always good though. Better than needing after hours service.
Should I replace a capacitor on a blower that is still running, but at less than full power tech says it was originally 7. Sara - That is odd and I don't think it's the capacitor either. While I can't say for sure what is causing this I do know that some people with programmable thermostats will sometimes run into a schedule issue that perhaps was accidentally programmed into it and not realized. Maybe check to see if that is the case if you have a programmable stat. My ac works fine set at 76, stays at 76 until pm until am when it gets all the way up to 85!
We have cleaned the coils, hosed it down, etc. Any ideas what to try. If that is the case, it sounds like the compressor is perhaps going bad and while that may not be what you want to hear, those units aren't typically worth the repair vs.
That was a good unit. I am running a 13 year old GE in my bedroom, two weeks ago I noticed the compressor starting up only occasionally then no more, I changed the capacitor with a new one. After turning on the fuse and staring the unit, the compressor starts like a charm, when temp is reached it turns off and never on again. Switching off the main fuse and turning it on again after a few minutes and it will do the same thing again, compressor starts once only, no matter the settings Seems as though the compressor isn't running.
There are two capacitors located at the outside condenser unit, I presume one for the fan and the larger one for the compressor?
Suggestions appreciated. Thank you very much, Dan! I really appreciate your input, Keep cool, it's the hottest day of the year. An AC tech said my capacitor is rated at 80 but is only operating at 60 and should be replaced. What do you think? Jeffery - There isn't much any homeowner can do when the compressor fails.
There are a lot of expensive tools and licensing required by the EPA to work on that type of repair. You're probably going to want to call a tech and be prepared. If the compressor is bad, the repair is expensive unless under warranty in which case the labor still isn't cheap and if your unit is R22 it's my opinion that repair is not a good idea and time to replace the unit. Hi Dan, my AC quit working. The compressor outside probably stopped working for a few day untill I noticed yesterday because there is no cold air blowing from the venst inside the house.
Unlike what you described here, the fan is running and from time to time, the compressor tries to start working can hear the noise and quit immediately. Any suggestion? Thanks a lot! It could cause issues since the rating is not in tolerance. These are not something you can just throw one in and expect it to work correctly. As stated in the article there is a tolerance. If you are not in that tolerance then it is likely you will experience problems.
Is that your issue? I can't say for sure but should it be there? There could be a few different reasons it's doing this so I can't really say which cause and which effect.
The problem is these are usually a replacement type part in themselves. You'd be supplying too much of a kick to the parts being fed from it. It may even work fine initially but eventually you'll have issues.
Samantha - Sorry but no I can't say what goes in there. I don't deal in that brand or type of equipment and it's a bit different of a ball game dealing with campers and RV's than homes.
Hi I'm staying in a camper with an air conditioner thats no longer working! The unit is a Coleman TSR and under the cover on the inside is a sticker that reads series air conditioner! Can you tell me what kind of capacitor it needs so I can tell my friend over the phone that way he can pick one up before he comes to fix it?
Russell Wilson - High amp draws and extreme conditions can cause this to happen but beyond that I really can't say. Sometimes is cheap manufacturing and others there's an underlying issue driving up the electrical draw The one you just bought should be under warranty however so perhaps you try once more and see if you just got a bad part right out of the box. Why does the capacitor go out? We replaced one Saturday, two days ago, and it worked like a champ for 3 days. What should I address next?
I appreciate your time and look forward to your response. Well it could but it wouldn't be anything you can reset yourself. Perhaps try shutting down the unit for a few minutes by shutting down the stat, then the breaker. Leave it sit for a few minutes then turn the breaker back on and then the stat and see if that might reset the switch.
I was told there may be a high pressure reset switch but I cant find it Does this make sense? Check a few of the simpler things like the low voltage wiring. Do you know how to test voltage? It could be a bad motor but it could be simple loose wire or bad board.
My outside unit works fine. But inside fan doesn't blow the air in the house. Symptoms point on capacitor which I changed today and nothing. The problem is still here. What would you advise to check next? The AC works itself. Heat starts only on aux heat for some reason. I dont know if it's related. Unplugged every cords and plagged it back in. Fan motor problem? Motor relay? How do I diagnose what is it? You're welcome Robert.
The capacitor itself should have the information you need written on it. If not, you can find out who the local Nordyne distributor is and give them your model and serial number and they should be able to tell you what's supposed to be in there so you can get the replacement. Very helpful. I attempted the fan blade test and it worked. Thank you Dan! And I will check my filter but it was just changed in March. I'm not sure if you're describing that there are 2 systems in the house one for attic and one for main living so if there is, it's possible the attic unit ran while the living area did not and thus the difference.
Beyond that, leaving the temp up at 82 while you were gone probably allowed a lot of humidity to sink into the home, woodwork, carpets, etc If not, then I would have a tech come and look for a problem. Always be leery when a tech says they need to "top off the refrigerant". That is not something that should ever be necessary unless there is a leak in the system and if there is, it should be repaired or sealed prior to any more refrigerant being added. That is one of the most common "suspicious" diagnosis that I hear people getting.
Aside from that, I really can't offer much sound advice without being there. I've written many articles on HVAC however so perhaps reading a few of them can give you a better idea of how systems work, what parts do, and either how to fix them or at least understand better what a tech is saying when he comes out and starts telling you what's wrong. I hope this helps a bit and thank you for reading. Hello, I found this page by searching for information.
I am an older woman with no husband who is determined to not be taken to the cleaners by repairmen thinking I am clueless. So I come home from vacation last night. Power outages occurred. But my homes time keepers were NOT blinking, so I have no idea if my power actually went off.
I had set myAC to 82 degrees while gone, and lowered the temp upon return last night. I went to bed, did not notice extra heat, or anything at all other than teenager has bonus room and attic is accessed in that room and he left light on while gone, so I went up to turn it off and to make sure no one was in my attic , I noticed immediately that it was cooler inside the attic in GA heat than in house and I know that is an unusual occurrence, normally that rooms AC runs continuously depsite temp inside room because the thermostat is on the attic wall and is always hot separate unit for bonus room.
Today did not notice it hot in house, but warm, came back home and felt it was warmer, checked AC, temp setting was on 68 and room temp showed That never happens. Motor is running outside. When I turn fan only on, no big change in air flow. Im worried abt coils but area is absolutley bone dry I was concerned abt this as this unit was replaced for this very thing as it had fallen in on previous owners, but all is fine.
Thank you in advance for any advice you can give. Iam capable of changing a capacitor via instructions, just unsure about where to start checking currently for options to repair on my own!!! John B - It could be but that doesn't mean it is.
Often, breakdowns will happen after having sat for a season and then the first time it kicks on Perhaps a capacitor, fuses, tripped breaker, contactor is dirty Unfortunately, just not enough information for me to say much more than that with confidence. No hum, No fan? Worked fantastic last year.. Could this be just my capacitor? Siraj - I don't believe your capacitor has anything to do with your issue in this case and I'm not sure there is anything you can do to shorten that restart time.
Perhaps unplug the unit for about 30 seconds and then plug it back in and see if that might help. I have window ac..
I just want to reduce the restarting time of my compressor to 2 or 3 minutes.. Snyteacher - Did they say why they added refrigerant? That shouldn't be necessary unless there is a leak or was never right. There is never a need to add refrigerant without one of those reasons.
Maybe there's a short or perhaps your panel is overloading?? There's a pull for too many amps coming from somewhere. The fan stops because the breaker keeps tripping at the main panel. The fuses are fine. I had a repairman out here about 1 week ago and they checked everything. Could it be the capacitor? That said, if the unit is running then the capacitor is not likely the issue.
The outdoor unit is supposed to blow warm air if that is what you're referring to. If everything is running seemingly proper and you're still getting warmer air, you may have a refrigerant charge issue but that would require a tech and specialty tools and licensing to test and determine. My Lennox dual zone AC unit is blowing warm air. I've checked the capacitor and unfortunately , I'm not seeing the soda can bubble.
Christy Trotter - I'm sorry but there isn't much advice I can offer on this one without running some tests however I can say I do not think it's the stat because whatever it would be telling the outside unit would affect both parts, not just the compressor. I have a Lennox outside air unit. Ive noticed that my unit kicks on and u can see the fan working. Then the compressor will finally kick on a few seconds after that. Then everything is going fine then all at once the compressor kicks off and then rite back on.
It does that a few times. Then finally it will cut off like it should. What could be causing this problem? I was thinking it could be the thermostat. When the compressor is kicking on and off the fan keeps going.
If replacing the capacitor didn't work then you may have a different issue. Keep in mind the skinny line shouldn't be cool at all. It should be warm. The larger one should be cool or even sweating under certain conditions. If these are not the case then you may have a refrigerant pressure issue and that is not something you can try and remedy yourself. Home Appliances. Air Conditioners. Water Heaters. Home Improvement.
