Question about Whirlpool GH7208XR Convection / Microwave Oven
2 month old convection microwave, turns on appears to work but stops at 9 seconds left and gives an error code #7
Behind the right front corner faceplate is a bag with the tech support info.
I used this and went through all the troubleshooting and got to the power inverter board. This board has the 2 red wires out of it that go to the magnetron. Instead of replacing the whole inverter module , I examined all the components on it. I found that there are 2 high voltage rectifier diodes attached to the transformer and 1 of them was not testing good. The diodes are UXC2B diodes.. Just clipped out the bad one and soldered in a new one.
Hope this helps..

My Whirlpool had the same problem (F7). I removed the keyboard assembly, revealing the relay board behind it. I wiggled each of the relays and found one that was loose. I unscrewed the relay board and inspected the solder joints on the other side. Two pins of the loose relay had broken solder joints. I resoldered the joints and re assembled the microwave. It has been working fine since the repair.

Is that F7 or just 7?
F7 would indicate a bad keypad or a problem on the control board.
Being only 2 months old, I would contact Whirlpool customer service for support here: http://whirlpool.com/custserv/index.jsp
