Customer Question
My furnace is not...

My furnace is not igniting. The blower motor runs for a bit and the I hear a clicking sound, and then it sounds like the gas starts going just before it all shuts down. I am thinking I need a new ignitor?

Contractor's Assistant: Did you check the furnace's filters?

Yes, the filters have recently been replace. The air flow is good.

Contractor's Assistant: Do you plan on doing the work yourself?

If possible. I am a little handy and can replace capacitors and small ancillary pieces like that. I would not be comfortable beyond those types of things.

Contractor's Assistant: Anything else we should know to help you best?

I do have the model number, if that is helpful.

M​ost likely the problem is the gas valve is either shorting out, or has an internal problem. If the ignitor is coming on and the flame is igniting, the ignitor is basically doing its job, and something else is causing the gas valve to shut off quickly. This is usually from a direct short or no power to the gas valve.

D​oes the ignitor glow orange and then click off after about 40 seconds?
