Model RBS275PDB12. I had a recent Power Failure. Since the oven has malfunctioned. When placed on bake the preheat timer does not display. At 350, the baking element gets warm. At higher temps the heat icon displays, the element gets hot, but then after a few minutes the heat icon goes off and element cools. On broil, the broil element glows red. I did not verify how long it stays on. The baking element ohmmed out correctly and so did the oven sensor (it ohmed at 1100 with digital meter set on 2000). With the meter set a 200, I did not get a reading for the oven sensor. What else should I check? My guess is that the control board or micro computer is bad. but not sure. Thanks

Rob, sounds like it was just installed. You need 240V on this unit. On the terminal block in back where the power hooks up, it should read 240V across the two outer terminals and 120V from each end to center terminal. Im ruling out the thermal cut out because you never used it. I would start with the power source first. The display sounds like it's getting the 120V it needs to funtion, but I don't think your making the loop for the 240V needed for the bake and broil. Catriver.

On these older ovens ther is usually always 120 volts on the elements at all times.
If you check across the element ends with it in bake you should read 240V. If not, there is a problem with the control. With the voltage drop you describe, it sounds like you are losing power on one line of voltage coming to the element.
Post back to let me know what you find out or if you have any questions.

F2 Oven over temp - exceeded 590F with door in unlocked position or 990F with door locked If actual temp condition occurred, look for welded relay contacts or high resistance connection or any cause in the oven temperature sensor circuit
