Furnace Won’t Stop Running? You’d Better Go Catch It!

Hey there, folks! It’s that time of year again when the leaves fall, the temperature drops … and furnace problems become, well, a problem.

But what do you do when your furnace is on a never-ending marathon, refusing to give itself a break? (Which may mean it soon gets a break.)

Fear not, because today, we’re diving into the mystery of the perpetually running furnace, and how you can put a stop to it.

1. Check Your Thermostat: First things first, head on over to your thermostat. Is the fan set to “on”? It might sound obvious, but sometimes the simplest solutions are the best ones. A fan set to “on” will keep running. But if the fan is set to “auto,” or, if you even turn the thermostat “off” to troubleshoot and it still runs, it’s time to move on to the next step.

2. Relay the Message: In this case, the culprit might be a malfunctioning relay switch. What’s a relay switch, you ask? It’s like the traffic cop for your furnace, directing when the fan should turn on and off. If this switch goes rogue, it can cause your fan to run continuously. Time to call in the professionals at Mechanical Man (cue the superhero music) to fix that switcharoo!

3. Blown Fuse Blues: Much like your holiday lights, furnaces can also experience blown fuses, and when they do, it can cause the fan to run continuously. To fix this issue, you’ll need to replace the fuse. But remember, safety first! Make sure to turn off the power to your furnace before attempting any fuse-fiddling.

4. Duct Dilemmas: Your furnace might be running non-stop because of ductwork issues. If there’s a leak or damage in your ducts, the furnace may struggle to reach the desired temperature, which can result in the fan working overtime. Inspect your ducts for any visible damage or loose connections. If you find any issues, it’s time to get those ducts in a row (pun intended), with Mechanical Man’s help.

5. Squeaky Clean Filters: Lastly, a clogged air filter can also cause your furnace to overwork itself. When filters get dirty, they restrict airflow, making your furnace less efficient. This can lead to the fan running longer in an attempt to reach the set temperature. Make sure to change your filters regularly to keep your furnace in tip-top shape.

So there you have it, folks! When your furnace goes into overdrive and won’t quit, check your thermostat, inspect the relay switch, investigate your fuses, examine your ducts, and change those filters. Or, to really get the issue fixed, call the experts at Mechanical Man.
