Concord plus 80 ignitor


Hello experts,

I'm looking all over the web to purchase a flame sensor/spark ignition for a 1997 Concord HVAC unit. This part has three prongs. Two are for the ignitor and the other is the flame sensor, all in one.

Can someone please help me locate this ignitor....please. We're freezing.

I can post a pic if necessary...

The sensor/ignitor looks similar to this one.

My only concern is....will it work on my particular furnace if I went and purchased it?

No and it may be dangerous. The position of the spark is CRITICAL for it to have proper ignition. you may end up with delayed igniton, flashback of the flame and a small explosion if it is not correct. also your house ins and fire inspector may have a issue with it. what is wrong with it? unless the porcelain is cracked or very black and conducting electricity to ground they last 4ever with careful cleaning with steel wool.

Yuri,

Thanks for your reply. I know my ignitor is defective because it wasn't sparking at all until I cleaned the 3 dirty prongs. Now it lights more often but it often takes three or four times for the sparks to finally occur and gas to finally light. I'm not sure what else I can do to avoid the issues with lighting.

the spark generator (transformer) in the circuit board may be getting weak and producing a poor spark or the prongs are too far apart/not set to the factory specs.
