3 Odd Reasons Your Furnace Isn’t Starting

Your furnace is pretty reliable and powerful. It springs into action every time you need it, but it can run into trouble from time to time. The problems don’t always present in a normal way, though, and it’s important to know what to look for so you can spot those uncommon furnace issues.

While these problems all result in furnace repair in Eugene, OR, it’s good for you to know whether or not the problem you’re facing is a real threat to your furnace, or if it’s just a minor inconvenience. Let’s talk about that.

Your Thermostat Could Be the Culprit

Your thermostat has a very basic function: it detects the air temperature in your home, and then sends an “ON” or “OFF” signal to the furnace. Your furnace doesn’t know what the specific temperature is; it relies on the thermostat for its orders.

If your thermostat is on the fritz, it could be confusing your furnace, and make it look like your furnace simply isn’t working properly. If your thermostat is hardwired, try checking the calibration. If it’s a wireless unit and has batteries, slide it off its dock on the wall and change the batteries, then return it to its spot.

If neither of these approaches solve the problem, or if you don’t know how to calibrate your thermostat in the first place, you can always call us to come out and help.

Your Flame Sensor Is Clogged

The flame sensor on your furnace has an important and pretty straightforward task: detect the flame. If there’s no flame, it shuts off the flow of gas, otherwise it would just leak into the air and cause a fire hazard. The flame sensor is a simple component, but it can get clogged with soot and not work properly.

Instead of the flame being detected, your furnace just keeps attempting ignition to no avail. Simply put, a dirty flame sensor is a small problem that leads to a major disruption. In many cases, this needs to be removed and cleaned, then replaced. That’s a job for your HVAC technician.

Exhaust Pipe Blockage

We don’t have to explain why it’s bad to have your exhaust clogged, but we can explain how: leaves from nearby trees, dust that builds up over time, soot, and even birds’ nests. If your exhaust is clogged, your system should shut off by itself immediately. There are fantastic safety features at work within your furnace, but then it can be confusing as to why your furnace starts up and stops shortly after.
