Circuit Breakers and Fuse

Most likely, either the electrical system that powers your furnace has become short or the power switch has blown. Try resetting the circuit breaker on your furnace. If the valve blows, you will need to replace it.

Igniter

The fire furnace’s igniter might either be cracked or faulty.

Check for cracks and if there are any, replace the igniter. If it is not cracked, then use a multimeter to test for continuity.

Thermostat

There is a possibility that your thermostat is adjusting incorrectly, causing the furnace to cycle on and off too often. If your thermostat has a calibrated scale that is adjustable, adjust the heat anticipator. If this does not cause the temperature to rise and stabilize the unit, it is possible that you will have to replace the thermostat.

Blower Motor

There is a possibility that your blower motor has completely burned out. If that is not the case, the connection belt may have just broken.

Check to see if the motor is producing power. If it doesn’t, but it is still not running, then the motor has probably failed. If the motor runs, but the air doesn’t move, it is probable that the connecting belt is broken. You will also need to replace the belt.

Control Board

It is on the control board that regulates the amount of voltage that will reach all the parts that are used. When the relay that controls the blower motor is failing, it will continue to send voltage to the motor. Then, replace the controller.

Thermostat

If that contact is stuck closed, the blower motor on your thermostat may continue running continuously. You can check continuity using a multimeter. If it appears that the thermostat is the cause of the problem, you should replace it.

Flame Sensor

The flame sensor on your furnace monitors the burner, detecting if there is a flame. If the object in question is defective or dirty, it will not be able to detect a flame. If the sensor is dirty, clean it with a finely abrasive pad. If your flame sensor is faulty, replace it.
