Why won’t my furnace turn on? There’s nothing worse than coming home on a cold winter day to find that your furnace isn’t working. If you’re like most people, you probably don’t know how to fix it yourself. We’ve put together this troubleshooting guide to help you figure out why your furnace won’t turn on.
We’ll walk you through some common problems and provide solutions for each one. So, we’ve got you covered whether your furnace is completely dead or just not turning on!
Furnace Switch Is Turned OFF
You should examine the furnace power switch if your heating system doesn’t turn on. The power source for the furnace is the switch, normally placed on the side of the appliance. It looks like a light switch. Ensure that the switch is in the “on” mode, and then wait for your furnace to start. Your furnace won’t operate if the switch is in the “off” position.
Check Your Circuit Breaker
A furnace that won’t turn on can also result from a tripped circuit breaker. The circuit breaker is located in your home’s electrical panel and controls the power to your furnace. If the furnace has a tripped circuit breaker, switch it back to the “on” position. Then, wait for your furnace to start. If the circuit breaker trips again, your furnace may have a more severe problem. In this case, you should call a professional for help.
The Thermostat Is Turned OFF
If your furnace is not turning on, it could be because your thermostat is off. To check this, look at your thermostat and see if the display is lit up. If it’s not, then the power to your thermostat is probably turned off. To turn on the power, find the switch that indicates “on” or “off.” It’s usually located near your thermostat. Once you’ve found it, flip it to the “on” position. Then, wait for your furnace to start.
Loose or Damaged Thermostat Wiring
If your furnace still doesn’t turn on, there may be a problem with the thermostat wiring. Thermostat wiring can become loose over time, which can cause problems with the furnace. Check all the wires going to and from your thermostat. Make sure they’re all securely connected. You may also need to replace damaged or worn-out cables. If you’re unsure how to do this, call a professional for help.
Gas Line Problems
Check to see whether the gas is on. By looking at the shut-off valve outside, you may verify this. Switch on another gas-burning equipment, such as the stove, to see whether the gas is on and functioning correctly.
Check whether the furnace’s gas supply is clear and open. If it seems that the gas line is not the problem, the gas flows to other appliances.
According to some theories, your furnace could not have enough fuel to burn when the gas supply is interrupted.
Call a professional to assess the problem and leave your house immediately if you smell gas or think there is a leak.
Faulty Pilot Light
The pilot light is a small flame that ignites the gas in your furnace. If your pilot light is out, then your furnace won’t be able to turn on. To fix this problem, relight your pilot light. The process varies depending on your furnace, so consult your owner’s manual for instructions. Once you’ve relight your pilot light, wait for your furnace to start.
If you’re thinking, “why won’t my furnace turn on?” This troubleshooting guide is for you. These are just a few of the common reasons your furnace won’t turn on.
