When you adjust the thermostat to heating mode, you expect warm air to blast out of the vents, easing your winter chills. But, wait, your furnace isn’t turning on! You try knocking the temperature up, but still, nothing happens. As the reality of your situation begins to settle in, you worry about your pipes freezing, your kids catching a cold indoors, and having sleepless nights without any heat.

Before you enter full panic mode, consider these reasons why your furnace isn’t turning on and then schedule prompt heating repair from Renville County, MN, technicians.

Malfunctioning Thermostat

Often, the reason a furnace doesn’t kick on is that the thermostat hasn’t been switched from “fan” to “heating.” Make sure yours is set to heating, and the temperature is set high enough. If this doesn’t fix the problem, there could be an issue with the internal components of the thermostat. A licensed professional will need to work on the repairs to get it working properly.

Unlit Pilot Light

When the pilot light goes out, the furnace will not turn on. Check that the light is lit and that it stays on. If it keeps extinguishing, there may be a problem with the assembly or sensor. A service technician can quickly resolve this issue.

No Power

Whether you have an electric or gas furnace, it needs power to work. If you’re having furnace problems, check the circuit breaker to see if a fuse was blown. Then, make sure none of the wires have been chewed on by rodents.

Dirty Filter

You may be surprised, but even something as simple as a dirty air filter can prevent your furnace from kicking on. While troubleshooting the furnace, double-check that the filter is clean. If it isn’t, replace it so your heating system can have sufficient airflow.

No Gas Supply

You may have turned off the gas valve during the summer as a safety precaution but then forgot to turn it back to the “on” position. If it’s closed or only partially open, your furnace will not get a sufficient amount of gas and will then not kick on. Make sure you open the gas valve before cranking up the heat.

Faulty Blower Motor

If the furnace’s blower motor is malfunctioning, the furnace will not kick on. You can tell if there’s an issue with the blower motor by looking through the inspection window on most furnaces. If the light inside this window is green, the blower is working correctly. If it is red or not on, there’s something wrong with the blower, and it should be inspected by a professional.

Full Condensate Pan

Your furnace has a condensation pan that collects excess water. When this pan becomes full, the furnace will not turn on. It may seem like you can fix the problem simply by draining the reservoir, but it became full in the first place because there is a blockage in the drainage pipe or the condensate removal pump went bad. A certified HVAC technician should be contacted to perform repairs.
