Why Is My Pilot Light in Concord, NC Going Out?

Your furnace’s pilot light acts like an ignition switch that helps you operate it and keep your home warm. Knowing how to light it is essential, but you also need to know why it goes out. These are some common reasons why your pilot light in Concord, NC goes out and won’t stay lit.

Thermostat Problems

First, consider all possible issues with the thermostat. If the batteries are dead or too low, the furnace can shut down because it can’t keep track of your home’s temperature. Make sure it’s turned on and ready to go.

Poor Gas Flow

A poor flow of gas will change the color of the pilot light from bright blue to white or yellow. When it doesn’t have enough fuel, it will keep going out. A technician should check the gas line for clogs, and make sure you have enough fuel to run the furnace.

Drafts

Since the pilot light sits so low to the ground, it’s common for it to go out when drafts pass by. This is especially true if you forget to replace the cover after changing the filter or doing any other work. Any wind that reaches it can make it go out.

Dirty Valve

Another minor problem that affects the furnace is a dirty valve. The valve surrounds the pilot light and can accumulate dust and debris during the off-season. Turning off the furnace and cleaning the area around it should help.

Bad Thermocouple

If none of these problems affects the pilot light, it’s likely caused by a bad thermocouple. It may suffer damage that causes it to tilt to one side or damage that breaks it, or it may be dirty. Replacing this part requires professional heating services.

Considering the problems mentioned above will help you find out why your pilot light goes out. Call our team at Dulin Mechanical Services, Inc. to fix or perform any other HVAC service you may need in Concord, NC.
