My husband and I replaced the igniter module, following directions we found online. We removed the old one, replaced it with the new one, and thankfully everything is working great!
I had to remove the two separate components of the gas burner unit, each had two screws. I lifted then tilted the lower portion of the burner unit to allow access to the underside of the igniter. I removed the wire and then with an offset screwdriver I removed the single screw that held the igniter in place. I reversed the steps to install the replacement, very quick fix.
I was also very pleased with how quickly the order was processed and the part was delivered, only three or four days with standard shipping.
