Question about Thermador MBYB Microwave Oven

1 Answer

Microwave turns itself off after a couple of seconds

Our microwave, model MBY, turns itself off after a couple of seconds---doesn't matter what power setting it's on. The microwave is 5 years old.

Any ideas?

    The problem is the push-on connector on the upper door-latch switch; if the plastic around this WHITE 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 blades
    on the switch before reconnecting as the heat has likely left a burnt coating.

Whirlpool GH5184XPS-7 microwave oven dead, no power.


The problem is in the magnetron or the inverter board.

GE Microwave stops running


Mostly with GE I find this to be bad connections at the fuse holder or a bad fuse due to a bad fuse holder. It will break connection and reset the unit when the connection gets hot and expands and then opens and stops power from getting to the unit.

GE microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

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.

Panasonic Microwave only works for 37 secs no matter what time setting


If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

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!

Micrwave does not heat, and turns off by itself before time


Unplug the Microwave and remove the outer cabinet. Inside the cabinet will be a thermal insulated fuse, looks like the old buss fuses for early model cars but white. Replace that with the correct fuse which can be found at Lowes or Home depot and see if that solves the problem. Be careful not to touch any capacitors if they are in there.
