This is a doubble oven and I only have been using the top smaller oven for the past 7 years. Today I turn on the bake button, set to 350 and after 2 or 3 minutes I noticed that the top element was on and the bottom element did not get red or hot. I shut it down and try again and the same thing happened again the bottom did not get hot . Does thes mean the bottom element burned out ? Please respond. Thank You.

ANSWER Hi Johnny. Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. Remove at least one wire from the element and ohm between the 2 terminals. If you get 0-ohms or infinity(too great of a measurement) then the element part # 74004105 is open. Place the ohm meter to Beep/ohm setting, this will only work at 50 ohms and under. Then check the element terminals one at a time to element mount screws/ground. If you get 0- ohms or an audible steady beep then it is shorted to ground. Disconnect one wire from the element. REMEMBER -THIS WILL BE A LIVE VOLTAGE TEST. Place the meter on the 300 vac scale. Place one meter lead on one end of the element. Then with one lead disconnected, place the meter lead into the terminal end. Use elect. tape around the temporary connection for safety. Then place the clock command for bake and see if after the upper clock bake relay clicks and you should have 240 vac at the meter. If you only have 120 vac then the clock is bad. Make sure you are getting 120 vac to ground from the terminal block lead to the one side of the bake element. If not then inspect the wires / connections from there. If you have the 240 volts. then the element is needing replaced. Thank You.
