Replaced the igniter. Before the fix, the oven would warm up to the set temperature (say 400 degrees) then because of the weak igniter the burner would not relight for a long 20-25 minutes, oven would cool down (to around 250 degrees) so items would not cook thoroughly or on time. Now this 20 year old oven works like new, fires up the oven burner in 30 seconds and maintains temperature right on the money. Replacing the igniter was very simple thanks to your videos. Just two Philips screws mounting the igniter and the quick disconnect for the wire. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
