The lower oven on our Jenn- Air duel fuel range, after pre-heat, will operate for 5 to 10 minutes before the bake lite begins to flash indicating an error. The diagnostic code display indicates '1d12'. I have observed the broil element during pre-heat and after the set temperature is reached and it does not go off. Is this a control unit problem or is there a less costly solution to this problem?
Thank you. Harvey
Answer Harvey, The "1D12" error code, indicates an issue with the oven temperature sensor 12001656 " 1D12 > Runaway temp (650°F), door unlocked". You'll need to check the sensor resistance (1050 to 1100 ohms) at room temperature. you'll also want to test the resistance at the clock connector (White/P21 across pins 5 and 7 on the harness connector). Both the elements "cycle" when the oven is in the bake mode, during both the pre heat and bake program. If there is constant power to the broil element after 15 or 20 minutes of a cycle, then consider the ERC 5701M796-60.
