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.

When is a radiator fan supposed to start?

Temperature will often determine the time that a radiator fan starts up. A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit. A radiator fan uses its fast spinning blades to draw in outside air.

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.

Can a convection fan be used to cool a radiator?

If it’s cold outside (but not so could that it would prevent using the A/C), natural convection should cool the radiator adequately. Well the short answer is yes. The A/C requires the fan to run as part of the heat exchange process. The A/C runs on a separate circuit and is triggered by A/C system.

How does a fan lower the temp like an AC?

You also need to know how the fan lowers the temp like an AC. Most cooling fans will have motors that build pressure on the intake air and force it out through the blades (or bladeless in some models) to add more airflow and a cooling effect to the air it moves. Some fans will have multiple duties, as well.

When do you turn on the cooling fan?

Once the coolant temperature sensor detects that the engine temperature has exceeded acceptable levels, the cooling fans will be activated to keep the engine cool. Many vehicles come equipped with cooling fans that operate on more than one speed setting.

What happens when your AC Fan is running 24 / 7?

Better dehumidification. When your fan is on “AUTO,” moisture is able to drip from the cold cooling coils and drain outside. When the fan is running 24/7, that moisture doesn’t have a chance to drip outside. Instead, it blows back into your house, and, as a result, your AC then has to work ever harder to suck that extra moisture out of the air.

What does the fan setting on an air conditioner do?

What does the fan setting on an air conditioner do? The fan setting on an air conditioner gives you the ability to run the fan continuously or to have it go on and off automatically when the AC is cooling.
