why did my furnace stop working
There could be a variety of reasons why your furnace stopped working. Here are a few common reasons:
- Thermostat: If your furnace isn’t turning on, the first thing to check is your thermostat. Make sure it is set to “heat” and that the temperature is set higher than the current room temperature. If your thermostat has batteries, make sure they are fresh.
- Power: Your furnace may have lost power due to a tripped circuit breaker, a blown fuse, or a power outage. Check your circuit breaker box to see if any breakers have tripped or fuses have blown. If your furnace has its own on/off switch, make sure it is turned on.
- Pilot light: If your furnace runs on gas, the pilot light may have gone out. Follow the manufacturer’s instructions to relight the pilot light.
- Dirty air filter: A dirty air filter can cause your furnace to stop working. Check the air filter and replace it if it’s dirty.
- Faulty parts: Your furnace may have a faulty part such as a faulty thermostat, blower motor, or ignition control module. In this case, you may need to call a professional HVAC technician to diagnose and repair the issue.
It’s important to remember that furnaces are complex pieces of machinery, and there could be many reasons why your furnace stopped working. If you’re unsure about how to troubleshoot your furnace, it’s always best to call a professional HVAC technician for help.
