Well, the fan switch... if it has, say, four settings, then the first three settings simply select which resistor the current runs through, and the fourth typically is a circuit with no resistor.
No power to fan, fan motor is burned out, fan motor has seized up, control circuit for fan not working.
The 1996 Chevrolet Cavalier resistor pack fan control switch is located on the back of the fan motor. The fan motor is located directly behind the fan.
A typical blower motor relay only operates the high speed function.
The purpose of the fan fuse in a cooling system is to protect the fan motor from overheating by interrupting the flow of electricity if there is a power surge or electrical issue. This helps prevent damage to the fan motor and ensures that it operates safely within its designed parameters.
That is one big belt that operates that help turn the pulleys for the AC, Motor, Fan Ect.
Loose connection? on fan motor or heater control Bad fan motor?
In a typical package sequencer, the fan motor is started through a sequence that ensures proper system operation and safety. When the thermostat calls for cooling or heating, the sequencer activates the fan motor after a brief delay, allowing the system to stabilize before airflow begins. This delay helps prevent short cycling and ensures that the system operates efficiently. Once the fan is energized, it circulates air through the system, promoting effective temperature control.
Blown fuse, defective fan control switch, defective blower motor resistor pack, or defective blower motor.
Possibilities: blower motor, resistor, wiring, control in dash
Change the motor resistor under the dash first.
The fan control module is inside the main (larger/left) fan motor. It requires replacement of the entire fan. Your secondary fan may still work. Bench test it to confirm.
A whole house fan that only works on one speed may have a faulty motor or a damaged speed control switch. It could also be a problem with the wiring or the fan's internal components. It would be best to have a professional electrician or HVAC technician inspect and repair the fan to ensure it operates correctly and safely.
