Common Questions

What is the typical ohms reading for a 767A-374 ignitor?
A functional 767A-374 silicon carbide ignitor usually shows a resistance between 40 and 90 ohms at room temperature. An "open" or infinite reading on your multimeter confirms the element has failed and requires immediate replacement.

Can I touch the black element during installation?
No. Avoid touching the silicon carbide heating element with your bare hands. Skin oils create hot spots that lead to premature failure. Always handle the part by the ceramic base or use clean gloves.

Does this ignitor include a plug connector?
This specific 767A-374 model comes with stripped ends, allowing it to be hardwired or connected using the ceramic wire nuts often found in service kits, making it a versatile choice for field replacements.
