Several things could happen that cause your furnace not to ignite or turn on. Some of them have to do with the furnace itself, and others have to do with the power supply to the system. In a lot of cases, all that is needed is some seasonal maintenance. Read further to find out some of the reasons why your furnace won’t ignite at your home in Frisco, TX.
Tripped Breaker
In this case, your furnace won’t turn on at all. If the breaker tripped because of a surge or something similar, then resetting it will do the trick. If something’s wrong that’s causing the breaker to trip, then you’ll need an expert’s help.
Clogs in the Gas Line
Sometimes, debris can get into the gas line. You’ll need heating repairs from an expert to get your furnace going again.
Igniter Not Working
Even though they last a while, furnace igniters can be delicate. They’re usually made from ceramic or silicone compounds. They eventually wear out, and it won’t light if your igniter doesn’t work.
Dirty Burners
Debris and dirt on or in the burners will interfere with smooth lighting. Sometimes, the furnace won’t light at all. Having an expert clean them will get your heating system going again.
Flame Sensor Not Working
When it’s working, the flame sensor sends a minuscule electric current to the furnace board when flame touches it. It tells the system that the flame is burning safely.
If the flame sensor isn’t working, then it won’t send the current. The flame will then turn off. Two of the reasons that the flame sensor won’t work are if it’s dirty or if it’s worn out.
