Check the Furnace’s Filters

Filters are essential components of every furnace. They keep your furnace clean and may even extend its lifespan. If your furnace has been running non-stop for a while and the filters are dirty, they can cause your furnace to overheat and shut down. When this happens, the furnace will stop running, and you’ll notice that it’ll be very hard to get it going again. When cleaning the filters, make sure that you do it so that they are completely dry before putting them back into the furnace. If they are damp, they can cause your furnace to break down once again. To clean your filters and make sure they’re ready to go, use gloves and a vacuum cleaner to remove all the dirt and debris accumulated in them. When you’ve finished, place them back into their correct positions and ensure they are properly secured. They should be placed toward the back and above the motor.

Check Your Thermostat

The thermostat is the heart of your furnace. It’s what makes the entire system work. It will be impossible for your furnace to start if it’s broken. You should check it to see if it’s not very accurate. If it is, you’ll need to replace it. If your thermostat is digital and has a wireless connection, check for any issues with the wiring or the batteries. If you don’t see any issues, you can reset it and see what happens. If your thermostat is not digital, or you see issues with it, you’ll need to replace it with a new one.

The Furnace’s Blower

The blower is the furnace part that blows air through the system and heats the house. If it has been used a lot and it’s broken, you’ll need to replace it. To do that, you should shut off the power to the furnace and remove the covering. You can then access the blower and remove it. To put in the new blower, do the opposite and ensure that you put it in the right way. When replacing the blower, make sure that you check the motor’s RPM and ensure it’s within the proper range. You can remove the blower and then take the motor out if it’s not. Then, use a screwdriver to adjust the speed to make it higher or lower. You can then put it back together and put the blower back.

The Burners and Gas Valve

If your furnace has been on for a long time and you see that the burners aren’t lighting up, it might mean that the gas valve is broken. If that’s the case, you’ll need to replace it. To do that, shut off the power to the furnace and remove the covering. You can then access the gas valve and remove it. When you’ve removed the gas valve, check the connections. If they are loose, tighten them. To replace the gas valve, you need to be careful. Make sure that you buy the right model and replace it with the same kind. If you don’t, you can make the problem much worse. Make sure that you install the new valve in the right way.

The Furnace’s Electronic Control

The furnace’s electronic control is the part that makes the furnace run. If it’s broken and can’t get it working, you’ll have to replace it. Before you do, however, make sure that you turn off the power to the furnace. When replacing the furnace’s electronic control, you need to make sure that you buy the right model. If you don’t, you can cause the problem to get even worse. Once you’ve bought the new one and opened the control box, remove the old one and put the new one in its place.
