When I turn on my bottom oven to bake or broil the elements start to heat up but the electronic control turns off within 45 seconds or so. What part do I need for the repair? Are all parts still available for this model?
You will want to do a voltage test at the terminal block. Pull the unit out and access the terminal block. Check from the black to white for 120 vac. You will want to power the unit on to the bake cycle and watch the voltage to see if there is a voltage drop. If there is a voltage drop of more than 10 percent then the issue will be the supply power to the unit, either in the power cord or home electric. If there is no power drop at the terminal block then do the same test from L1 to neutral on the control board and if there still is no voltage drop then the issue would be the control board. If there is a voltage drop of more than 10 percent then it will be caused by the wiring in the L1 circuit which you will want to trace the wire back to the terminal block to find a loose or broken wire. If the clock WB27K5047 is the issue, the part has been discontinued by the manufacturer with no replacement.
