If you have a gas furnace, it’s a good idea to understand what is normal and what is not when it comes to operation. This can help you identify the early signs of gas furnace problems so you can catch them and fix them quickly, ultimately preventing a total system failure. When you’re ready, call us to schedule your furnace repair in Plymouth, MN. Keep reading to learn everything you need to know about common furnace problems, including the signs of each one.
Blower Motor
If the blower motor inside of your gas furnace doesn’t work, heat can get trapped in the heat exchanger and never make it out into your home. This can lead to the system overheating and shutting down as a safety precaution.
When this happens, your furnace may continue turning on for heating cycles, although quickly turning back off again since the blower motor is not moving heat through the system. Sometimes, the blower motor gets jammed, and we have to do a little tweaking. Other times, we need to clean out the bearings and lubricate them to get the system working again.
Thermostat
It’s also possible that furnace problems are not actually furnace problems at all. Instead, you may be facing issues with the thermostat attached to your furnace. Your thermostat has the job of reading the indoor air temperature and signaling for your furnace to turn on when it dips too low.
But sometimes, it does not read the indoor air temperature correctly because of miscalibration or does not communicate to your furnace the way it should. This can result in your thermostat not turning on and off correctly for heating cycles. Many times, fixing a thermostat is as simple as recalibrating it, cleaning it out, or changing the batteries. Other times, we have to replace the thermostat entirely if it is older and outdated.
Ignition
We often see issues with ignition in gas furnaces. In this case, the blower motor may be working just fine to move air through the system, but the ignition is not working to create the heat necessary to increase the indoor air temperature.
Ignition problems can involve the gas valve, the pilot light, or both. Sometimes, safety mechanisms inside the heat exchanger prevent proper operation, and those need to be adjusted. No matter what the issue is, we can determine its root cause, fix it, and prevent it from happening again.
