The purpose of this article is to provide a comprehensive guide on how to identify these common issues so that you can be able to solve them quickly and effectively. Let’s check out some of the common problems and their possible solutions.


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.


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.
