When winter descends on Bremerton and surrounding areas, you can expect your home’s furnace to run quite often. However, by no means should be running all the time. If you notice that your furnace continues to run even when your home has seemingly hit its target temperature, it might be caused by one of these issues:
- Thermostat’s settings or wiring
- The furnace’s fan limit switch
- A dirty furnace or air filter
Learn more about why these issues can cause your furnace to keep running, even when your home is at the right temperature.
Your Thermostat’s Settings or Wiring
One of these is an easy fix while the other will require professional assistance. If you have set your thermostat’s fan setting to “On,” the fan is going to run all the time, no matter what temperature the thermostat might be set at. You can easily change it over to “Auto” to fix the problem. If the wiring in your thermostat has shorted out, then the thermostat will not be able to properly communicate with your furnace. A trained HVAC professional can replace the wiring to remedy the issue.
Your Furnace’s Fan Limit Switch
The fan limit switch is the component that tells the blower when to turn on and off. If this switch becomes faulty or is on the manual setting, it isn’t going to automate the process how you would expect. The switch is easy to find — it’s located just inside the furnace panel, giving you an easy opportunity to check it.
Dirty Furnace or Air Filter
When your furnace’s air filter becomes overrun with dirt, dust, and debris, it can cause the unit to overheat. This will kick on the fan to cool it down. To avoid this fate, replace your furnace’s air filter or clean it off if it’s a reusable model. You can also remove the panel from your furnace and vacuum out the dust.
