    That is what I did and it is working fine now, though I had a hard time finding where the fuse is and how to take it out and place another to replace it.

No power to viking microwave unit.tripped fuse in house and than reset fuse but doesnt work.


Check to see if you have a "reset" button on your microwave, or even just by pressing the "clear" button first. Check to see if you have a "master" or "red" reset or "test" button nearest to your microwave on a light switch and reset that if applicable. You could also check to see if your unit has a fuse and replace that. It's possible when you tripped the fuse in the house you might have blown the fuse in the microwave.

What does a small d mean on the digital display? The microwave is not warming food. The model number is GH7145CFQ. Thanks


I'm assuming you mean model GH7145XFQ1?

It may be in "demo" mode or the door may not be shut properly, or the door switch or door switch mount may have a problem.

The owner's manual for the GH7145XFQ1 (here) doesn't address this.

I would suggest that you unplug it for a couple of minutes, then plug it back in and set the clock. The is called a hard reset, and it may be what it needs.

If it still does this, then the door switch or its mount have a problem.

Our file on door switch trouble is here.

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

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Good luck.

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.

Microwave won't turn on. Seems like it is not getting power. I checked breaker. I am looking for a fuse. You know where one is? It is a GE Spacemaker(2 yrs old) model # JVM1440WH04


  • Make sure that the microwave is plugged into a grounded outlet. It must be a 3-prong outlet.
  • Make sure the clock is set.
  • Check to see if a programming sequence was entered. Sometimes improper programming or a program sequence such as delay start can cause the touch panel to be non-responsive. Unplug microwave or turn off house circuit breaker for 30 seconds. Plug back in, or reset circuit breaker, and try reprogramming unit.
  • Check the house circuit breaker or fuse box. If the microwave is DEAD and there is no display and nothing works- the problem could be a blown fuse or tripped breaker.

No power from Whirlpool.


IF YOU HAVE THE MICRWAVE PLUGGED IN AND THE CIRCUIT BREAKER TRIPS IMMEDIATELY WHEN SET,
CHECK THE DOOR HOOKS THAT TRIP THE DOOR SWITCHES. BOTH SHOULD BE SPRING LOADED. THERE SHOULD BE TWO HOOKS ON THE DOOR. IF O.K., CHECK THE DOOR SWITCHES. THERE ARE AT LEAST THREE. IF ONE OF THEM IS SHORTED CLOSED,
THE MONITOR SWITCH WILL CAUSE A DEAD SHORT ACROSS THE FUSE. THE FUSE MAY BE HOLDING BETTER THAN YOUR CIRCUIT BREAKER.
