Product review (5 stars): whirlpool ignitor
My oven would not stay at the desired temp and I didn't want to pay for a service call, labor and part so I bought this item and the oven sensor and with the help of a few U-tube videos, I installed the parts myself. It's been about 40 days since I  installed the parts and my oven still bake foods at the desired temp. I think I paid 60 for both items. Tools needed was a Phillips screwdriver, and a socket wrench. Very easy to install. Dont touch the ignitor or wear gloves while installing.
