When does the air conditioner fan turn on when the AC is on?
The fan only turns on when cooling or heating (in winter) is required. If you can tolerate most of the summer heat – save for the absolute hottest of days – you’ll want to use the AUTO setting. The AC fan kicks in when needed and stops running when the job is done. Beside above, when should the cooling fan come on?
How does an engine cooling fan work in a car?
The engine cooling fan is designed to move air through the radiator when the vehicle is at slower speeds or stopped. This air flow removes heat from the coolant created by the engine using the radiator as a conductor.
Why does the radiator fan have to start when turning?
The A/C condenser (the part which sits in front of the coolant radiator) is a heat exchanger. If air isn’t flowing over it, it won’t exchange the heat it needs get rid of so the A/C core inside the vehicle can become cold and make you comfortable. If the fan didn’t come on, you’d still be warm inside.
Why is my AC fan running but the compressor is not working?
A working AC will provide you with nice and cold air as opposed to bearing the brunt of warm, dry air. With how much the HVAC runs, something is bound to go wrong with its compressor. However, having the fan running but the compressor not working is nothing too dire, so don’t panic.

How does a radiator fan work when the AC is on?
The electric radiator cooling fan assembly is controlled by a thermoswitch located in the side of the radiator. At higher coolant temperatures, the switch closes to start the cooling fans. Any time the coolant temperature rises to higher than normal levels, the fan will start and continue to run until coolant temperature returns to a normal range.
Why are my cooling fans not turning on?
If the compressor is running long enough to build heat in the high side of the system, and the cooling fans don’t turn on, I would begin finding the fan relays and add power to the appropriate circuit to see if the fans turn on at all. This will require a wiring diagram.
When does the cooling fan come on in a car?
Beside above, when should the cooling fan come on? To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective.

Why is it important to keep your HVAC fan running?
There are a few positives to this feature. Keeping the fan on creates a more even distribution of heating and cooling, circulating the air if you have cold or hot spots in your house, like a bedroom above a garage. Less frequent starts and stops of the fan can reduce the stress from startup, and potentially help extend it’s lifespan.

Is the fan supposed to be on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. Click to see full answer. Similarly one may ask, is the fan supposed to be on when AC is on?
Why do I need an electric engine cooling fan?
Usually, electric fans will activate shortly after the air conditioner is turned on, this is done to dissipate the extra heat produced in the condenser while the air conditioner is in operation. Engine cooling fans are temperature controlled to only run when needed.
