    It is the "internal cooling fan" that stays on.. When microwave door is shut, "internal cooling fan" blows and the turntables turns with no light. Turntable also turns if any buttons are pushed like time set, etc Light does not go on if buttons are pushed.

    I have the same problem. I opened the door to put something in. The light got real bright and then went out. After that, light doesn't work and internal fan runs when the door is closed. Everything else seems to work, we just have to leave the door open to stop fan from running.

    Technician said that when light blew, it shorted the control board. Need to replace light and control board. Is this true? Obviously we need to replace light, but from reading this thread, it appears we just need to replace relay, or possibly relay board. Any ideas

    Same problem I have. My inside light has been out for a few months. Finally got around to replacing it. When I did, now the fan comes on and the light and turntable are also on when the door is shut. But a cup of water in there won't get hot.

    Which fan is it, the internal cooling fan or the hood vent exhaust fan?

    Also, when this happens, is the turntable turning?

    When I say internal
    cooling fan, I do not mean the hood vent exhaust fan which you can turn
    on and off manually.

    I'm instead talking
    about the internal fan which comes on automatically whenever you

    Fan, interior light and turntable would not stop running when I closed the door. However, the microwave did heat food. I followed the instructions to get into the control panel and tapped on the relays with a screw driver. Sounds crazy but it worked.

Looking at the schematic in the service manual here, I would say relay RY6 on the small sub PCB (relay board) has shorted contacts.

That's the relay that runs both the fan and turntable.

It's possible that it may be a bad connection or driving component on that board, but in my experience, it's virtually always a stuck relay.

The part number on the relay as shown in the photo is hard to read, but it looks like "OJ-SH-112LM".

I should have one of these or I can point you to one if you want to contact me with the exact number.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

Ours does this from time to time. I simply disconnect the power for a few minutes, close the door, and reconnect the power. Sometimes have to repeat the process one or two times, but it eventually works.

Have a look at this. Hopefully it's the same problem and solution for you as it was for me. I did not expect it to work, but it did and I have had no problems since.

Advantium 120 Keeps running

I've got this problem also.
The interior light on the oven died. We replaced it. Since replacing it the light stays on and the turn table turns.

Looking at the diagram, the "main relay" is what powers both. My guess is that it's stuck in the "on" position. Solution will be replace the relay.

Long term fix may be bigger relay.

Fan coming on unexpectedly

Frannie, this is the way the oven is designed. There is a thermostat in there that is normally open. The thermostat will close at approx. 140 degrees and start the fan. When the temps. cool to about 104 degrees the thermostat will open again and the fan will shut off. back.
