James Hello. I have a JKP90SP4SS General Electric Microwave Oven Combo. The microwave is giving me trouble where the fan was running when door was open. I replaced all 3 door switches and the fan still runs with door open and microwave does not work. Oven seems to be fine. Now there is no display on the microwave portion of the control board, just oven portion. Do I replace the board or should I explore getting a new line fuse, part WB27X10388? Thank you. - Jay
Answer James, Based on the fact you have already replaced the switchs you are likely to have a relay on the board that is stuck closed. Based on this info you will need the board and the fuse. Read More... Answered by AppliancePartsPros.com | Monday, September 9, 2019
