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 have a central air conditioner should the circulation fan run only when the compressor kicks on or is it better to always leave it on?

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.

Will a heat pump compressor burn out if the circulation fan does not work?

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.

Does air conditioner take a lot of power from battery?

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.

Does the compressor come on if you have the fan only running on your home ac unit?

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

Where is the condenser fan relay for a 2002 Kia Sportage?

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.

I have a Heil heat pump. Even with the temperature in the house at the setting of the thermostat, the blower runs constantly. Is this normal The outside compressor shuts off when the house is at temp.?

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.

Why ac compressor and cooling fan does not kickin for 2004 Honda Civic. Fuse is okay.?

The ac compressor's clutch may be blown. If so the compressor will not spin and provide air. The fan could also have a bad motor which will stop the fans from working.

What do you need to do if the inside blower on your air conditioner does not cut off?

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.

What is the desired outlet air velocity of fan coil unit?

How do you clean a Duracraft window fan?

try an air compressor.

What causes the AC compressor to continue running and the freon to continue to circulate after the fan inside the house clicks off?

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"

Home air condition is blowing air only?

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

Should the fan for the AC in your house kick on constantly if the thermostat Heat-Cool is set to off and the fan On-Auto switch is on Auto?


Why your ac not working on your 1996 Mazda 626?

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.

What does it mean when your ac is blowing hot air?

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.

Why does outside fan run constantly even if the thermostat is turned off inside?

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

What should you do when your central air compressor is running but the cooling fan is not working?

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

Why do you keep blowing fuses when you turn on the heater fan but when you take out the compressor fuse it doesnt blow the fuses?

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.

If my Condenser fan didn't work for a day could that ruin my air conditioner?

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..

Why is the fan running in the unit outside but no air blowing on the inside?

compressor not running

Why is the strip between your side by side refrigerator is hot?

check compressor fan.

Is the compressor motor and condenser fan motor wired in series or parallel?


Should you continue to be an Oakland Raiders fan?


Should you run your heat pump on auto or on?

Auto, and that switch only controls the fan.

What could cause the compressor to come on but the fan to stop rotating on a central air conditioning unit?

Bad fan motor or bad capacitor.
