Furnaces are an essential part of keeping homes warm and comfortable during the cold
winter months. However, like any other mechanical device, furnaces can experience malfunctions and breakdowns. Some furnace malfunctions can be minor and easy to fix, while others can be more serious and require professional help. In this essay, we will discuss some common furnace malfunctions and how to fix them.
The Furnace Won’t Turn On
One of the most common furnace malfunctions is when the furnace won’t turn on. There are several reasons why this might happen, such as a tripped circuit breaker, a blown fuse, a faulty thermostat, or a malfunctioning pilot light.
To fix this issue, you can follow these steps:
Check the circuit breaker: Make sure that the circuit breaker for the furnace is in the “on” position. If it’s tripped, reset it and try turning on the furnace again.
Check the fuse: If the circuit breaker is not the issue, check the fuse. If the fuse is blown, replace it and try turning on the furnace again.
Check the thermostat: Make sure that the thermostat is set to the desired temperature and is in the “heat” position. If the thermostat is not working correctly, replace it.
Check the pilot light: If the furnace has a pilot light, make sure that it’s lit. If it’s not, follow the manufacturer’s instructions to relight it.
The Furnace Blows Cold Air

To fix this issue, you can follow these steps:
Check the pilot light: If the pilot light is out, relight it. If it keeps going out, there might be a problem with the thermocouple or the gas valve. In this case, you should call a professional.
Check the gas valve: Make sure that the gas valve is open. If it’s closed, open it and try turning on the furnace again.
Check the air filter: If the air filter is dirty, it can restrict airflow and cause the furnace to blow cold air. Replace the air filter and try turning on the furnace again.

To fix this issue, you can follow these steps:
Check the blower motor: If the blower motor is dirty or clogged, it can cause the furnace to make strange noises. Clean the blower motor and try turning on the furnace again.
Check the bearings: If the bearings are worn out, they can cause the furnace to make a high-pitched squealing noise. In this case, you should call a professional to replace the bearings.
Check the belt: If the belt is loose or worn out, it can cause the furnace to make a rattling noise. Tighten or replace the belt and try turning on the furnace again.
The Furnace is Short Cycling
If the furnace is short cycling, which means that it’s turning on and off frequently, there might be a problem with the thermostat, the air filter, or the flame sensor.
To fix this issue, you can follow these steps:
Check the thermostat: Make sure that the thermostat is set to the correct temperature and is not located near a drafty area. If the thermostat is not working correctly, replace it.
Check the air filter: If the air filter is dirty, it can restrict airflow and cause the furnace to short cycle. Replace the air filter and try turning on the furnace again.
Check the flame sensor: If the flame sensor is dirty or malfunctioning, it can cause the furnace to short cycle. Clean or replace the flame sensor and try turning on the furnace again.
The Furnace is Not Providing Enough Heat
If the furnace is not providing enough heat, there might be a problem with the air filter, the ductwork, or the gas supply.
To fix this issue, you can follow these steps:
Check the air filter: If the air filter is dirty, it can restrict airflow and cause the furnace to not provide enough heat. Replace the air filter and try turning on the furnace again.
Check the ductwork: If the ductwork is damaged or clogged, it can cause the furnace to not provide enough heat. Inspect the ductwork and clean or repair any damage.
Check the gas supply: If the gas supply is not sufficient, it can cause the furnace to not provide enough heat. Make sure that the gas valve is open and that the gas supply is not interrupted.
