THERMOSTAT WB27X10864

I was preheating this oven when it suddenly shut down and had no power. After checking breakers and finding that there was power to the outlet, I purchased a ceramic fuse and replaced that. It didn't help. Then I ordered part #PS2339856 THERMOSTAT(PLATE) and we replaced that (the old one tested bad), but the oven still would not power on. Those were the quick and easy potential fixes that only involved removing a couple of front panels.

My husband is a retired electrician, so I trusted him to work on this. After doing quite a bit of research, we learned that there is yet another thermostat deep in the bowels of the machine that apparently prevents the oven from overheating. That seemed to fit the situation, because the oven was very hot when it shut down.

We took the oven down (mounted over the range and very heavy!) and opened it up. Using PartSelect's very helpful diagrams (In this case "Interior Parts 2") we located and removed the part labeled "27," which is #PS1016683 THERMOSTAT. The old one tested bad, so I ordered a new one.

Lo and behold, it worked! This is a very expensive oven -- in the range of $600 -- so I'm very pleased that this $20 part and several hours of research and work were able to repair it.
