See if your motor is okay 1st. Find your wires feeding your Fan motor. (This means the 2 power wires L1 & L2 if 220v or L1 & N if 115V) Carefully put the power to these 2 wires and see if you hear the motor hum or start. If it hums the run capacitor could be bad.Try spinning the motor with the power applied. If it starts most likely the run capacitor is out. If it starts without you helping it the control board or switch is most likely out.

It is possible the unit has a energy saving setting. If it gets locked into this the fan may not run.
If the unit has electronic controls and an electronic display read out, the board is the most likely suspect. Unplug it and see if it resets.
If not then the board is probably out with a stuck relay or stuck program. New board time. Or replace the unit.

If it has a rotary or push button type control then either of these 2 switches are suspect.

2002 4 ton Bryant air conditioner shuts off, fan still runs but not cooling is problem in the controls in the attic or in the AC unit or both?


With a non heat pump it is a simple 24 volt AC control circuit. In the attic there is a relay that is actuated via the fan control wire directly from the thermostat. On the thermostat there is an auto/man switch that controls the fan. Manual the fan runs all the time. Auto fan turns on and off with the outside compressor.

If the system is not calling for cool and the fan continues to run the fan relay is sticking. common problem. Sometimes after running for several days the relay will stop sticking if not, replace relay.

If the system is calling for cool and the compressor stops I would still expect the fan to run until thermostat tells the A/C to off. Some compressor units include a safety switch or high-pressure cut-out switch A blocked internal valve bad control board or external fan in outside unit defective no air flow in outside unit.
High pressure cut out not good,

Suggest turning temp max cool and observe. If acceptable cool and the compressor runs without interruption all is good, except for the blower in the attic. Safely check relay in attic blower circuit.

Hope this helps.

I have a Fredrich 8000btu wall unit model number CPO8F10 and the compressor will not shut off, even when the unit is turned off the compressor keeps running. the only way to shut it off is to unplug...


If your air conditioner or heat pump compressor won't shut off unless you pull the fuses or turn off the circuit breaker. You probably have a stuck contactor. The contactor is the name we give to the big relay that controls your air conditioner, heat pump or other large electrical device. If the indoor blower fan will not shut off either then the problem is NOT the contactor in the outdoor unit but a problem with the thermostat or the wiring to it either at the subbase or the furnace. Before replacing your thermostat you should isolate the cause of the problem or it will persist and drive you nuts. Look for wires touching or cut too long. A contactor or relay is an electrical device that takes a control signal usually 12 volts DC, 24, 120, 208-230 volts ac and creates a magnetic field to pull in a set of contacts that controls another device that may or may not get its electrical power from the same circuit. Note: 99% of most control circuits are 24 volts AC. The contactor has steel contacts that are plated with silver. When the silver wears away you have just plain steel and the steel will weld itself together. Sometimes if you whack the contactor with a screw driver you may free it for a while but the problem will re occur. This problem is especially a problem when a piece of equipment has not been run for a period of time. It is normal for the contactor to wear out over time like brake pads on a car. If the contactor shows any signs of wear it should be replaced as a preventative measure or as part of maintenance. If you suspect a stuck contactor a 100% accurate test is to turn off the power to the indoor section which removes control voltage to the outdoor section and it (outdoor section) keeps running. Do not keep messing with it, your contactor it is bad and you will destroy your compressor if you let it run!!! You can also have problems with spiders building nests in the contactor; the silk is an insulator and will prevent electricity from flowing. Replacing a contactor is a simple matter and they are readily available. Costs vary from about $40 installed to several hundred dollars depending on the size and current carrying capacity. If your compressor does not shut off when it needs to and the indoor fan does you will destroy your compressor. The high and low pressure cut-outs won't work either.

When my ac window cuts off after it gets to the set temp. the compressor keeps running and if you mannualy turn it off the fan cuts off but not the compreesor.


the contact are welded shut. the selector switch has to be replaced if it is a window unit. If its a split system the contactor in the outdoor unit needs to be change.

Home ac compressor fan won't turn all the time.


your looking at $175-$225 for just the single phase motor depending where you purchase, I just replaced mine(identical unit) due to screaming dry bearings, if you replace it your self make sure to keep new wires tight along side of unit or fan will cut them if loose and its a fan- 5mfd/25mfd compressor@440volt cap

The compressor on my home ac willnot kick on


The fan and the compressor both run off of the same circuit. Have your husband remove the cover on the condenser coils and check for power at the leads that go to the compressor off of the latching relay. If there is power there, then he needs to check the start capacitor or possibly the thermal overload switch (mounted on side of compressor)

Fan will not shut off, but compressor does


hi! there, continous fan motor when unit was shutt off,since supply source was already cut off specially on fan condenser motor,the supply of your motor was came from relay mounted on your circuit board control panel,there a holding coil to hold the connection between your fan and ac source,shut off breaker for ac unit first before diagnosing ac unit, try to check this out the relay is still activated giving ac source when shut off,the contactor on relay holding your ac supply was shorted,try to check the connection the circuit activating condenser fan relay,eliminate the short circuit,using multi tester test rod,use manual diagram for circuit control board to lessen complicated diagnosing,focus on fan relay ac source then isolate checking the short circuit replace defective relay,contact point of relay are not repairable.take necessary precaution on checking to avoid shock,this a hard task i would suggest that certified ac technician w/ full knowledge of instrumentation should do this.thank's for selecting fixya and have a nice day.

    sounds like your contactor is stuck closed.This is the part that high voltage connects to and lets power through to the compressor and condenser fan motor when you get a call for cooling.If you go to pull it out,kill the power outside AND at the furnace.
