Top 6 DIY Furnace Repair Tips

Even if your furnace is well maintained, there is still a chance that it might break down. If such a thing happens, you will need to know the right way to repair the furnace to avoid feeling uncomfortable in your house. There are some furnace problems that you can repair by yourself while others require an expert to fix them. If the furnace has a problem that is beyond your understanding, be sure to call a furnace repair company so that a professional can come and look at it, otherwise, you may end up making the problem worse. The following are some DIY tips you can use to repair your furnace:

Look For the Manual That Came With the Furnace

From the manual, you will be able to understand what make and model your furnace is. You will also be able to learn whether the furnace is covered by any warranty that you can use to repair it. If the furnace is still under warranty, you will need to call the helpline number and find out if they can help you fix the problem.

Do Not Panic

Sometimes, you might hear banging or knocking noises coming from the furnace. Do not panic if that happens because it might simply be due to the rapid expansion as well as contraction of internal mechanisms of the furnace. Calmly take your time to establish the cause of the problem before you start looking for solutions.

Find Out the Possible Cause of the Problem

If your furnace becomes noisy all of a sudden or stops producing as much heat as before, you will need to find out what is causing that. Such problems could be caused by pockets of air that are trapped in the furnace, which is usually due to decreased water flow or a build-up of sludge from corrosion or limescale. Be sure to rectify it or call a professional to rectify it.

Check the Thermostat of the Furnace

Among the issues that cause the furnace to stop working properly are thermostat malfunctions. The thermostat is the control device that determines when as well as how much heat the furnace will produce. You will need to remove the thermostat cover and gently clean components especially the switch contact surfaces and the bimetallic coil.

Check for Blown Fuses, Tripped Circuit Breakers and Lose Wires

Blown fuses, tripped circuit breakers or lose wires are all problems that you can easily fix. You will need to replace the fuse if it is blown, reset the circuit breaker if it is tripped and tighten the screw terminals if the wires are loose.

Evaluate the Pilot Area and Thermocouple of the Furnace

A clogged pilot opening could also cause the furnace to malfunction. You will therefore need to check the pilot area and then clean out all blockages if there are any. Also check if the thermocouple of the furnace is in good condition. Make sure that it is tight enough to make the pilot stay lit.
