Replaced two sensors(one in each oven). So far, seems to be heating ok. I was worried that the temperature control would have to be replaced. Had trouble getting one of the screws holding the sensor, to unscrew. Ended up cutting the screw, other than that, the operation is pretty straight forward. The oven does have to be removed from the cabinet. Lucky the power wire had enough lead to pull all the way out. Remember to cut power at circuit first. Saved probably $300.00 doing it myself.
