This will be the 4th time I have replaced the Hi Limit thermal fuse. I also replaced the Blower motor last time. Whenever I clean the oven we blow this thermal fuse. What else can be wrong with the oven? Do I need to replace something else? The last time the repair man was here he told me not to use the auto clean, simply hand clean. I did not buy a self cleaning oven to hand clean it. Any suggestions?
Answer Tommie, You also need to check the oven door and door gasket. Open the oven door as far as possible, if the door goes past a 90 dgr. angle, then you will need to check and replace the door hinges and receivers. Also check and make sure the door gasket isn't damaged or allows air to enter the oven cavity. Lastly you want to check and make sure the installation is correct. Improper air flow in and around the wall oven can cause the oven to heat erratically and cause the thermal fuse to open.
After running (attempting to run) the self clean cycle, thermal fuse blew and power to oven went out. I replaced the fuse but still have no power to the oven!! And suggestions?
With the control board not coming on you will want to check the transformer for the display. The part number is 9760587 and you can test it by doing a voltage test. You will test for 120 vac at the P16 connector from pins 5 to 7 and check for 12 to 24 vdc on pins 2 to 3 of the same connection on the control board. If there is 120 vac to the transformer but no voltage out then the transformer is bad. If there is no power to the transformer then you will want to check from P19 pin 1 Black to Pin 3 White to make sure that there is 120 vac at this point. If not then check at the terminal block to make sure that there is 240 vac across the outer pins and 120 from each of the outer pins to the center terminal. If there is not correct voltage check the breaker. If there is proper voltage at the control board but no power to the transformer then the control board is faulty and would need to be replaced.
