Question about Heating & Cooling

1 Answer

The electricity went off in our neighborhood yesterday. It came back on. I do not run my central air this time of year so the air conditioner is in off position. My fan is on auto but this usually means it is also in off position. When the electricity came back on yesterday the fan came on (not the air conditioner) and is continually running. I cannot get this darn thing to shut off. I have looked on the internet and made serveral attempts to get this fan shut off. I do not want to pay for electricity we dont use nor have the fan run continuously when we do not need it. I reset my thermostat. Shut the air on then off to try to reset. What can I do?

Hello Sounds like runaway blower.The relay in the blower unit is stuck/welded & should be replaced.In the mean time you can turn off the service switch at the unit.If you tap the relay it will shut off (for now) untill the next demand and get stuck again.The relay can be of many types and locations ,trace the wires from the motor to a small box/cube and tap it to free it.

Compressors can fail at any time, how old is the unit? You should get at least ten years from a factory installed compressor, Be `sure to get a filter dryer installed on the new one

My central air conditioner was working fine but the power went out for about 2 hours and when it came back on, my air pump runs and the air conditioner fan is running but it blows warm air. What gives?


mcdevito75 here, Your A/C units control board is most likely transisterized or computer built, in which case when power went out so did the memory in your A/C control board. Simply shut down your A/C unit, re-start and make adjustments again for your comfort.

Hi!!

Replace motor fan and capacitor of the outside unit. it is a very simple task. Turn breaker OFF. Then all you have to do is remove about four screws from the top grill, about four more that fasten the motor fan assembly, unplugg electrical connectors and label them and install the new one and switch fan blades.

No special knowledge is required to perform this job. Cost: about $140 +-.

On the other hand, you call a HVAC technician, they supply the motor and capacitor, otherwise they won't give you warranty. Cost $300. Look on the Yellow Pages for one in your neighborhood.

Good Luck!! Rate this post!!

I have a GE central air conditioner model


If you are talking about the indoor fan it is probably a bad capacitor. Replace the fan motor capacitor. And YES, if the fan motor needs replacing too, you can DO-IT-YOURSELF.

Central air conditioner won't stay running


Sounds like it cycles on either head pressure or low pressure. If you have a Carrier unit it has both controls. Is your outside fan running. Is your condensor dirty. A unit that old needs to checked bby a service tech. Remember freon does just go away. If he puts gas in your unit there is leak. HINT Ask for free estimate on repair before it is fixed. That way you know the cost up front. Rus

sounds like the control fuse may have blown , this is inside the outdoor unit and unless you have some experience with electrical stuff i would recommend a trades person to carry out this test

Furnace runs on heat, air conditioner does not


If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.

Central air


Most thermostats have a setting for the fan called, "manual". That keeps the fan on continuously. The electronic thermostats can fail in a "fan on" condition. That would require a new thermostat. I also saw one air conditioner with a fan relay welded "on" by electrical surge. That would require a new relay.
