If you have the fan set on auto why does it continue to run after the compressor has cut off?

Your fan relay is stuck or you have a bad tstat. Check your auto fan (summer fan switch ) on your furnace if equipped. Mostly older oil furnaces.

If you want constant air movement in you home leave the fan on. If you just want the fan to cycle on with the compressor, move the switch to auto. It does not harm the fan either way.

If the fan outside is not running the compressor will overheat and if the fan inside the house is not running the compressor will get liquid refrigerant back to it and lock up! Neither is good for the compressor.

With an auto air conditioner, the main power consumption is by the compressor. The compressor is driven mechanically by the engine, not the battery. Electrical power is used for controls, and to power the blower fan.

Main components of AC are compressor & fan motor. The louvers are operated by fan motor which is powered separately. When the louver is off, it doesn't affect compressor work. - Be-Cool Expert <><><> possibly a stuck contacter in the outdoor unit. or your indoor fan is overheating and shutting off <><><> could be many different things. Depends on what system you have. Some of the newer machines are controlled by integrated circuit boards. Its a possibility that your indoor blower could be tripped off on thermal overload but honestly I doubt it. Possible contact could be stuck on compressor. T stat could have a problem but would need to know if the compressor ever turns off after the "fan inside the house clicks off"

1. Is the fan and compressor on the outside (codensor unit) working? A. Thermostat switch off, set to fan only. B. Check the circuit breakers or fuses. There may also be a fuse box near the compressor. C. The control wire to the compressor is cut or broken. D. Low freon. E. Burnt out compressor. F.Capacitor( run or start)or both is bad

Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.

The Condenser Fan Relay and the A/C Cut Relay on a Kia Sportage are located together under the dashboard on the passenger side of the vehicle. They are just aft of the heater blower motor. The Comndenser Fan Relay is the 20amp relay and the A/C Cut (compressor) relay is the 52amp relay.

Check your thermostat to see if it set for "Auto" or "Fan." If it's on fan then the blower will run constantly. Auto will shut the blower off when the correct temperature has been reached.

Fan at the compressor does not tun on humming noise

Check the thermostat. Make sure the fan switch is on auto. If it is disconnect the green wire from the control box at the air handler. This will disconnect the fan from the thermostat. If the fan continues to run, you have a stuck fan relay. If the fan shuts off, you have a bad thermostat.

First check your fuse for your AC in your fuse box, make sure it is good. Make sure your cooling fan is turning on when you turn on your AC, if not it could be your fan relay. If the AC compressor fan clutch is kicking on and off then it just needs freon. If the AC compressor fan clutch is not turning then it could be completely out of freon due to a leak, or you need a new AC compressor.

Check the capacitor located inside the outside condensing unit,usually the fan,compressor are wired together,if one is running the other should be running

Outer fan cools condenser coil as well as compressor. Even though the cycle is turned OFF the compressor needs to be cooled continuously.

The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.

Your compressor is not working. Through evaporation compressors cool the evaporator coil and the fan blows air across it. So if the fan is blowing hot air the compressor is not cooling the coil. But check to see if the dial inside the fridge is turned to "more cold" , that turns the compressor on.

Check your outside unit. Is the fan blowing? If not replace outdoor fan motor or the fan capacitor. If the fan is running then the compressor may not be. Usually a quick fix by replacing the capacitor. In most units a dual capacitor that is bad may shut down the fan or compressor. Call a HVAC technician to replace it. This can be very dangerous.

Answercheck fan operation( fan on fan hi when does it blow?I had the same was the clutch on the a/c compressor. Need to get another compressor.

Yes it would cause your compressor needs that fan to cool down the refrigerant going through your condensing coils.. Without that fan it would cause high head pressure and damage the compressor as well..

Auto, and that switch only controls the fan.

does your car have A/C? If yes theres a a/c fan switch located by the a/c compressor

No fan-electrical Fan/no cold-check refrigerant. Refrigerant ok, check compressor.

The compressor is located outside of the house in a metal box with coils in the sides and a fan in the middle of it to blow air through the coils. the compressor should be located under one of the side panels of the box.
