Re: No heat or fan movement

Probably a bad door switch or door switch mount.

I'd check to make sure you don't have a door switch that isn't functioning properly. Also, might be a control panel or control panel interface issue.

Microwave timer works but will motor will not run/cook.

If everything works on the unit, but you do not receive any heat or possibly the turntable does not turn you have a faulty magnetron (controls heat) and a faulty motor (controls turntable). You would require service on the unit, if parts are available. Some microwaves are so small in cubic foot size, that manufacturer's do not have parts available for purchase/repairs.

Mbbs 01 thermador micro oven: timer counts down, lights go on, but no heat, no fan and turntable does not turn. is it a fuse?

Key clue is table does not move---All microwaves with a table have a lever switch that is engaged when door closes--only can get at from inside the unit----it prevents the unit from operation if door not closed.

What happens from closing door a lot is the switch with a lever arm can come loose or even if snapped into a plastic holder break out of the holder.

IF this it is not too expensive a repair.

I would strongly consider replacing the microwave oven, prices have dropped considerably. The problem you are describing is in the keypad controller board.

Food won't heat up

Hello, I had the same problem, and just fixed mine. Start by turning on your microwave (on mine, the light turned on and timer worked, but the fan nor the plate turned)... push the door upward and see if the microwave turns on... (mine did). so far so good. open the door and take the upper hinge cap off with flat head screwdrive. take the door off and place a small washer on the bottom hinge, put the door back on. your microwave should be good now. essentially, the door just needs to be pushed up a bit so it will work.
good luck, hope that works for you...

Microwave turns on, but no heat or turntable movement

The problem is that the magnatron is not getting power. Chance is that if could be a bolwn fuse inside the unit. If the fuse don't fix it then that leaves the charging diode, capacitor or the magnatron, or high voltage xformer of which without technical epertize I would not recomend attempting to replace. good luck
