C.J. for Model Number JJW9527AAW My oven works fine but the display doesn't. I've replaced the oven control board but it still doesn't work. I then replaced the board, relay and still the display doesn't work. What can I do?
Answer Hello C.J., This sounds like the J1 harness is bad. You need to pull the J1 harness off of the display board and check for 12Vdc from terminal 1 to terminal 2 on the harness. Then test for 20Vdc from terminal 3 to 4. If these voltages are not there, verify the issue from the relay board. If the voltages are at the relay board, the harness has failed. If not, you have received a bad relay board. If the voltages are everywhere they should be, you have received a bad display board. Read More...
