Why Won’t My Furnace Turn On?

What Is Causing Your Furnace Troubles?

A furnace that refuses to turn on is a real hassle — especially in the middle of winter. Furnaces are complex systems with several components that could be the cause of your breakdown. Is the flame sensor broken? Is the thermostat not working properly? Is there something blocking the gas line?

Our HVAC experts are here to get to the bottom of your furnace troubles and get your home feeling comfortable again.

Broken Flame Sensor

One reason your furnace may not be igniting is that the flame sensor is broken. The purpose of the flame sensor is to detect whether or not there is a flame present. If the sensor is not working properly, it will prevent the furnace from turning on. To fix this, you will need to clean or replace the sensor.

Faulty Thermostat

Your thermostat is the control center for your furnace. If it is not correctly reading the temperature of your home, it will be unable to communicate with the furnace, failing to heat your home. To fix this, you will need to recalibrate the thermostat or replace it entirely.

Clogged Filters

Another common issue that can prevent your furnace from firing up is clogged filters. Over time, dust and debris can accumulate in the filter, making it difficult for air to flow through properly. This puts strain on the furnace and can cause it to overheat. To fix this, simply replace the filter with a new one.

An Old Unit

Furnaces typically last about 15 years before they fall into disrepair and are in need of a replacement. If your furnace is on the older side and is beginning to require more frequent repairs, it may be time for an upgrade.
