3 Most Common Furnace Failures – Garrison & Garrison

Furnace Failures

Heating failures in the dead of winter are no joke, especially when coming from the source that heats your whole home: your furnace. However, not all furnace failures require a call for professional repair. Check out these common furnace failures to see if you can fix the problem yourself before needing to call your local heating company.

1. Thermostat

Nowadays, most homes have modern thermostats that run off batteries. Many times, when your heat hasn’t turned on in a while, you may find that your thermostat batteries have died. Replacing the batteries on your thermostat can be done easily. Simply remove the thermostat from the base plate, find the battery port, swap the batteries out, and replace the thermostat to its base. Once the thermostat turns back on, your heat should too.

2. Filters

Filters prevent dust, pollen, mold, and other airborne particulates from circulating through the air in your home. If your filter is clogged, it’s likely you’re not experiencing sufficiently comfortable temperatures in your home. Severely clogged filters can even prevent air flow and drive up your energy bills. Fix this issue by changing your filter regularly: every 1-3 months.

3. Igniter

When your furnace is signaled to turn on, natural gas or propane is ignited in the burner. This is the flame that heats your home when your furnace is running. As your system ages and the igniter lights thousands of times, it will eventually wear out. Unfortunately, at this point, there’s nothing you can do besides replacing it. 

Regular preventative maintenance includes inspection of parts such as this to predict when they are on the brink of failure. This way, you have the option of fixing the problem before having to go without heat.
