Chase C Tulsa , OK July 13, 2015 Oven not reaching correct temperature (tepid) I originally thought the RTD probe (temp probe) had become damaged or un-calibrated. Replacing the RTD sensor did not fix the problem. I replaced the controller & everything worked perfectly! Problem Solved! The control board is incredibly easy to replace. Almost anyone can do it. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
