Although power/circuit breaker is on, there is no power to the control board. When pushing "Upper Oven" and "Start" a short beep, followed by a long beep, followed by three short beeps are heard.
I purchased two of the 4451042 fuse from you. Two questions: Is that the right fuse and if so do I have to remove the oven to get to the back to remove a cover over the lower oven area to change the fuse? Or can you tell me where it is located?
To access the fuse there is one of 2 ways to do this. The first way would be remove the control panel and try to access from the front and the other way is to pull the unit out from installation and remove the top to get to the fuse. You will want to also check on the control board from the P7 pin 1 to P4 pin 10 to see if there is 120 vac at this point. If there is then the thermal fuse is good and you would need to replace the control board which would be at fault.
I have this unit double oven, the light inside comes on but there is no power to the panel, I have checked the house breaker but still nothing , when I push the upper start button it starts to come on then beeps and shuts off. model RBD305PDB8, I have read on your site about the fuse can this be the problem ,Thank you
The most likely cause of the issue with the panel beeping but not having power would be the transformer. You will want to test the control transformer part number . To test you will check for 120 vac at the P16 connector pins 5 and 7 and check for 12-24 vdc on the P16 connection pins 2 and 3. If there is 120 vac to the transformer but not 120 vac out then the issue would be the transformer. If there is not 120 vac to the transformer then test for power on the P24 pins 3 to pin 1 and see if there is 120 vac and if there is then the control board is faulty. The transformer part number is 9760587.
If I need to replace a thermal fuse, how do I do that?
Answer Hello Jim. Access the back of the control board. Where the wiring harness comes into the board, you will see the old fuse in the harness. You remove the old fuse and install the new fuse into the harness of the unit.
