Learn How to Troubleshoot Common Furnace Problems

Learn How to Troubleshoot Common Furnace ProblemsDuring the long Alberta winter, one skill that can’t be undervalued is the ability to troubleshoot furnace problems. If you can quickly figure out the problem with a non-working or poor-performing furnace, you’ll be that much closer to fixing it or calling in professional help. You don’t want to be left without heat when the temperatures fall below freezing, nor do you want a heating system that struggles to maintain comfortable temperatures. Least of all, you want to avoid the safety hazards associated with a faulty combustion furnace.

If your furnace stops working, or won’t turn on, check to see whether it’s getting power. If a circuit breaker has tripped, reset it. Also look at the thermostat to make sure that it’s set to “heat,” that the temperature setting is above the room temperature, and that it has fresh batteries.

If none of these troubleshooting steps addresses your furnace problems, check the pilot light to make sure that it’s lit (in an older furnace). If repeated attempts to light the pilot are unsuccessful, or if something appears amiss with the electronic ignition (in a modern furnace), call a professional to perform a repair.

If furnace problems are preceded by loud rattling or banging in the furnace, especially near the blower motor, the problem may be a loose or disconnected part or slipped belt. While some handy homeowners may be able to replace the belt, other issues with parts likely will need professional service.

Popping or small explosions from the combustion chamber may be caused by dirty or clogged burners, igniting the air in small bunches rather than largely and smoothly. A furnace technician should be called in.

If the furnace is working but not heating adequately, there are multiple possible culprits, including a dirty air filter, leaky ductwork, an aging furnace and more. Each has a different solution, ranging from changing the air filter to replacing the furnace. You can minimize furnace issues by scheduling annual preventative furnace maintenance.
