Why Won’t My Furnace Ignite?

A malfunctioning furnace can become a hassle during Wheat Ridge, CO winters. There are several things that could be causing your furnace to not ignite, but there are a number of fixes available. Read on to learn about some potential problems that could make your furnace fail to ignite.

Circuit Breaker Problems

In some cases, the reason your furnace will not ignite is because something caused the circuit breaker to trip. Power surges can cause an electrical overload in the circuit, which results in the circuit shutting off as a protective measure. This prevents the circuit from providing heat to the furnace, however.

Lack of Gas

Sometimes, when technicians perform heating services in your home, they will temporarily shut off the gas line for safety reasons. In some cases, they may forget to switch it back on, which results in your furnace not receiving the gas it needs to function. A quick turn of the gas valve should remedy this issue.

Faulty Ignition Sensor

The furnace’s ignition sensor is a safety feature that will cut off the gas supply if the burner does not ignite properly. This is to prevent gas buildup that could become dangerous. If the furnace has not received any cleaning in a long time, dirt can accumulate in the burners and cause problems with ignition.

Malfunctioning Flame Sensor

The furnace’s flame sensor normally regulates the amount of heat produced, but sometimes it may malfunction and turn off the flame by accident. This normally acts as a safety measure, but it may shut down the flame even when it isn’t supposed to.

As you can see, there are a variety of things that can cause issues with your furnace. Because furnace repair can be a tricky process, it helps to have a professional come and inspect your furnace.
