The problem is the push-on connector on the UPPER door-latch switch; if the white plastic around this connector is brown (burning), the connection is going bad.

Cut the three white wires back about 1 inch and strip; obtain a new push-on and solder the three white wires into it-- a crimp is NOT sufficient for three wires into this little connector (defective design). Also clean the two blade on the switch before reconnecting as the heat has likely left a burnt coating.

If you try to heat something for a minute , the microwave will turn on for about 15 seconds then shut off . It doesn't even seem to warm the food.


It may need a reset. You can do that by unplugging the power for a minute or two, then plugging it back in and setting the clock.

If it still fails, you may have a failing cooling fan or a problem on the control circuit board.

Goes to cooling down and shuts down -Thermador MBY


It sounds like the magnetron is overheating. There can be several causes:

- the vents are blocked
- the outside outlet of the air duct is damaged or has an animal nest in it
- the filters need to be cleaned (if grease filters) or replaced if charcoal filters
- the magnetron is failing

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

Microwave turns itself off after a couple of seconds


Q - My microwave seems to shut off every once in a while, what might be wrong?
A - Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt.
Q - The fan in my microwave oven is not running will this hurt my microwave?
A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace.
Q - My microwave blows the fuse inside itself as soon as I push the start button.
A - Usually a shorted high voltage capacitor...see components section.

Door not latching


One of my friend who can fix almost anything is coming once a year to fix all that is broken and not working. It has become a yearly routine. This works out way more cheaper than trying to fix all these "wonderful" appliances myself!

Thermador model CM302UB displays error F34 when microwave is in use for morwe than 2 minutes


There are two main possibilities. The first is that the main circuit boards in the oven are not being properly cooled. The second is that there arere are some components that have become thermo sensitive, and are acting with heat.

Check to make sure that the vent fan is working properly. Check to see if the vent hole in the rear of the oven is clogged with a lot of dust. If there is dust, clean it out.
