How To Troubleshoot An Overheating Furnace?

A furnace is an integral part of your home's HVAC system, working tirelessly to warm the air in your home, circulating it, and maintaining a cozy environment for you and your family. While a furnace is designed to handle heat, like all machines, it has its limits.

Pushing your furnace beyond these limits could lead to overheating, causing several problems and disrupting your home's heating equilibrium.

An overheated furnace is more than just a nuisance; it is a serious problem. In most cases, an overheating furnace will automatically shut off, leaving your home uncomfortably cold. Furthermore, the furnace would likely have sustained severe damage by the time it reaches this stage, necessitating emergency furnace repair.

In this comprehensive guide, we'll delve into the telltale signs that your furnace is overheating, and how you can troubleshoot these issues. We'll also discuss the steps to take when you need furnace repair in Vancouver, Burnaby, Surrey, Coquitlam, Langley, Maple Ridge, Port Moody, Richmond, British Columbia, and what actions you should take if the furnace continues to malfunction.

Identifying The Symptoms of an Overheating Furnace

Your furnace may give off certain signals when it's overheating or on the brink of overheating. Being vigilant and responding to these early warning signs can save you from a heating disaster in the cold months. Let's take a look at some of these symptoms:

Factors that you can observe in your furnace to identify overheating problems - Ariana Heating & Air Conditioning Ltd

Burning Odor

If you notice a burning scent that's not the typical smell of dust being burnt off when you first turn on your furnace in the fall, you might have a problem. This burning smell could indicate that your furnace is overheating, possibly due to a blocked filter.

Humming Noise

If your furnace is making a humming sound, it could be a sign of a problem with the blower motor. If the blower motor isn't functioning properly, the furnace won't be able to disperse heateffectively, leading to complications. Other noises could also indicate that your furnace is on the brink of overheating.

Furnace Shuts Off

If your furnace shuts off and then fails to turn back on, even when the temperature in your house dips below the set temperature on your thermostat, it's likely that your furnace may have overheated.

Understanding these common furnace problems can be less intimidating once you know how to identify potential issues and understand the steps required for furnace troubleshooting. Armed with this knowledge, you can save time and money by knowing when to seek professional help and ensure that your home stays warm and comfortable this winter.

Steps To Troubleshoot An Overheating Furnace

  1. Adjust the Thermostat: Lower the thermostat to its minimum setting.
  2. Disconnect The Power: Turn off the power to the furnace at the fuse box.
  3. Control The Gas Supply: If you're using a gas furnace, turn off the main gas supply valve, but leave the pilot gas supply on.
  4. Relight The Pilot Light: If the pilot light was extinguished, relight it using a match.
  5. Reconnect The Gas Supply: Now that the pilot light is on, you can reconnect the main gas supply.
  6. Press The Reset Button: Locate the reset button, which is usually red, and press it. You may need to hold it down for about 30 seconds.
  7. Reconnect The Power Supply: Reconnect the power supply to the furnace.
  8. Reset The Thermostat: Reset your thermostat to your preferred temperature.

While these steps may seem straightforward, it's essential to note that attempting to repair your furnace without the proper tools, training, and certifications can expose you to the risks of electrical and burn injuries.
