Doug J Prospect , KY December 04, 2016 Whirlpool wall oven that would not hold temperature or would seem to loose track of what the set point was Some on line research showed that the control board was probably OK -- however the RTD had most likely gone bad. The part I ordered and you sent appears to have solved the problem. The repair took about 15 minutes to complete. Only because some idiot at the factory taped the lead wire to the back of the cabinet -- so I had to pull the oven out of the wall to get to the wiring in the rear of the enclosure.
