Troubleshoot Your Furnace Ignition

Furnace repairs can be very complicated tasks if you don’t know what you are doing. It’s not unusual for a homeowner to take their furnace completely out of service and leave it sitting for weeks until they return to find that the furnace has ignited and burned down. There are ways that you can avoid these disasters and hopefully, you can catch it before this happens so you won’t have to worry about having your furnace blown to pieces. Keep reading to learn how to troubleshoot your furnace before it goes up in flames.


turned off the power furnace

The first thing that you need to do is ensure that the power to your furnace has been turned off. You can do this by flipping the switch on the furnace. If there is a sign on the box indicating that the furnace has been left on, then you should also assume that it has just been turned off. Take note of where the furnace goes up and down so that you can identify the switch so you can go up and flip it yourself.


turn off the main power supply

Next, check to make sure that the power to the furnace has been turned off as well. This way, you won’t have to run any wires or fuses. If your furnace ignites and burns down, you will have to locate the area where the power is coming from and you have to turn off the main power supply to get it running again. If you are replacing the furnace, you should consider purchasing a kit that has a transfer switch that allows you to manually switch the furnace on and off from anywhere in the house. If you don’t have this type of transfer switch, then you may need to install an actual furnace switch on each panel to shut it off from the main panel and shut it off from the main room.


stop the fire with water

One possibility is that the actual fire may be starting to burn in the furnace. If so, then you may want to try to stop the fire with water. If the fire is not getting extinguished, then it may be time for you to actually call the Fire Marshal. The Fire Marshal will be able to either cut off the supply of gas to the furnace or to actually put out the fire.


the wires have actually come loose and are starting to cause a fire

You can usually easily detect where the loose wires are and then you can cut them with wire cutters. If the wires are located in areas that you can’t easily access, then you may be forced to hire a professional to take care of the problem. A professional will either use pliers to pull back on the wires, or he will use a tool that is like a pair of wire strippers. It is important to know that both methods should work before you try to cut the wires.


As long as you do all of these things, then you should have very little to worry about. If the ignition is still functioning, then you may want to check to see if there are any other problems with your furnace. However, if your furnace has already started to burn out, then it is safe to assume that the problem is the ignition.
