Question about Whirlpool Microwave Ovens

Open Question

Whirlpool microwave oven model; MH7130XEZ-1 (built Jan 1998). My microwave is totally blank. Verified that I have power to the unit, but no display or no fuctions operate. Is there a power fuse internally that might have blown? or is it likely that the circuit board has fried?

I have a 13yr old above-range oven which quit when my wife cooked food in an aluminized foil wrapper (a small fire ensued!). This oven has 3 thermal protection units, on the magnetron, the chassis and on top of the food cavity. This last one had failed open, and since it's in series with the magnetron thermal protection unit and the main relay, nothing would work. MAT electronics sell the units for less than $4, but my problem now is to pick one with the appropriate temperature cut-off. They range from 200 to 300F.

Generally, the most common causes of a failure to heat are:

 

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

SOURCE: GE model JE2160BF03 no power. Blown fuse.

They are put out when something metal is put inside and cooked for a few min. They are also put out with power surge. It protects your mag tube. Plus they just go bad sometimes. Could be a number of reasons but these are the most common.

if unit won't heat, then there is a problem with either the magnetron or the diode. if its the magnetron, the microwave will sound almost normal. if its the diode, it will make a humming sound

Turned light on. Several minutes later the light


Your unit may employ a switching power supply and these have a tendency to cease operation without warning and servicing these may require training and a piece of specialized equipment.
With the unit unplugged, after an hour or two, it is safe to open the housing and check for an internal fuse which could have failed.
If typical, these will be in a tubular ceramic housing about 1 1/2" long and 1/4" in diameter and can be purchased at most hardware stores.

Service to Whirlppol MH7130xez-1, circuit breaker popped then unit went dead


water may have leaked inside unit causing a short.the transformer output is about 1400 volts that feeds a large capacitor. a direct short can blow the transformer instantly or any support parts without time to burn something. creating little or no smell. I never sujest that a person
to try to repair a microwave oven because
the capacitor can still be charged and very lethal.

Door


The door part# is 4359542 if you need the part number. If you need to know how to replace the door check up by the upper hinge on the inside of the door should be a plastic piece that you can remove so if you lift the door off of its hinges. You may or may not need to remove the grill above the door to raise the door high enough
