Numbers rubbed off your old part?
Ask us to find it
Send us your unit's model number and a photo of the plate. A real person will find the part for you.
What it does
It proves there is a flame. No signal, and the furnace shuts the gas off for safety.
Clean it first
A light cleaning fixes many sensors. Replace it if the rod is bent or worn, or the white porcelain is cracked.
Gas safety
Turn off power and the gas valve first. If you smell gas, leave the house and call your gas company from outside. Read the guide.
