How do I control the fan speed on my air conditioner?
The common method of AC fan speed control
- You can use TOROIDAL TRANSFORMER to supply lower voltages to the fan in order to reduce speed of the fan.
- It does not cause damage to fans by providing a lower voltage to fans.
- You can use a diac and triac to control supply voltages.
What do you need to know about radiator fan control?
The simplest form of radiator fan control is a switch that applies B+ voltage to the fan whenever the driver closes the switch, regardless of the ignition switch position. This arrangement is found on some race cars and custom vehicles. A disadvantage, of course, is that if the switch is left on, the battery will be discharged in a few hours.
How does the engine radiator fan control relay work?
Using a sensor the computer detects that the engine temperature is rising above normal limits, a signal is sent to close the fan control relay which is protected by a circuit fuse. When replacing these cooling fans match the failed unit with the new cooling fan. To check a fan clutch condition the engine must be “OFF”.
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?
Where is the cooling fan control unit located?
Control Unit. The cooling fan control unit is located under the left guard below the head light. Remove the inner guard cover to gain access. Temperature Sensor. The temperature sensor us mounted on the heather tank on the cylinder head at the bell housing end. The sensor is brown with a brown 2 way connector.

Is the radiator supposed to turn on when AC is on?

Then, is the fan supposed to be on when AC is on? The fan only turns on when cooling or heating (in winter) is required.
