Question about Whirlpool GH7145XF Microwave Oven

1 Answer

Whirlpool microwave GH7145XFseems to have shorted out. Is there a circuit breaker somewhere on the oven itself that can be reset? History: Trying to turn off the oven light when the door was open, I tripped the door latch manually but the whole oven shut down. I must have shorted something though there was no flash or noise or any other indication except all oven power shutting off. The dedicated circuit breaker in the basement had tripped. I reset it. Still no power on the oven. What can I do to fix this?

There should be a line fuse inside, and a less likely culprit would be the oven cavity thermostat.

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.

Whirlpool microwave GH7145XFseems to have shorted - mini_manual_behind_grille_small.jpgAt our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you don't find your mini-manual, or if you want to look at it before removing the controller, you can download it here (just enter your full model number without dashes).

Accessing the oven cavity thermostat for testing and possible replacement will require you to remove the oven from the wall and take off the outer cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download Whirlpool owner's manuals and installation instructions here.

If both of those components are bad, it may be a damaged control circuit board.

We can repair that for $39.95 in most cases, or you can buy a new "microcomputer" circuit board (part number 8169379) here for $146.66.

Microwave oven no power


The main fuse is probably blown.

When replacing, try to determine the cause.

if it has a bad door switch, then the monitor/short switch also must be replaced. On an inverter, replace the power relay as well.

If the fuse holder is not holding the fuse securely, then it will heat and blow.

A failing component in the high voltage circuit can also cause the problem.

How do you reset a whirlpool wall microwave oven


A reset may not correct your symptoms, which you did not reason, but here is how to do a "hard reset".

Unplug the oven's power cord or turn off its circuit breaker for about a minute, then plug it back in (or turn the breaker back on), then set the clock.

Whirlpool GH5184XPS Microwave Oven F7 error, trips circuit breaker


Check the high voltage capacitor, it normally shorts, "discharge with screwdriver" unhook one side and set meter to ohms. Check high voltage diode tied into one side of the capacitor, "unhook from chassis ground" set meter to ohms and check for short, sometimes cracks, "must be replaced" If the diode is open meter does not have enough forward bias to check.

My maytag microwave blew the ciruit breaker a several times last night. I reset the circuit breaker each time. Then the last time, I reset the circuit breaker and the microwave did not get power back....


If there's no other appliance on that circuit, then please stop trying to use the microwave. You could be dealing with a dead short, and those sometimes leave people,,,DEAD!

I would be really cautious about trying to use it anymore without checking it first for a direct short.

You need to allow the circuit breaker more time to reset, flip to off and give it 2 minutes, then turn it back on. You should feel the distinctive click, as well as hear it if it's working properly.

Circuit breakers can go bad after repeated failures within a circuit.

The outlet could also be damaged now, but normally it's the circuit breaker getting too hot with repeated failures.

If there are a number of other items on the same circuit, then try the microwave in a plug that you know has no other items being used at the same time, preferably while wearing heavy duty leather insulating gloves to protect yourself from any possible shock. If the circuit breaker blows, you've got a possible electrical short within the microwave.
Good luck!

Does the rf375pxdw whirlpool range have a fuse or reset button? burners and oven does not work. there is power from the 220 plug into the range and the clock operates but not the 220. I checked circuit...


No reset buttons or fuses. Find the circuit breakers for the unit, it should be a double breaker with at least 40 Amp rating. Push it to the off position HARD (make sure not to pull the breaker out of the panel doing that). Turn it back on. Check voltage in the range power outlet. It should measure 220-250 Volts between the right and left connectors, and 110-125 Volts between the center and each side connectors. If not - problem is in the wiring or breaker. If you get those voltages and the range is still not working - problem is in the range itself. Check for shorted and loose wires.

Oven has been working fine. Heating a cup of coffee it just stopped dead. No display. Nothing. Power to outlet working fine. Is there a reset somewhere?


Mine did this when my wife had it on full power for over 10 minutes. We left it set for 15 or so minutes and it came back on. It did the same thing when my niece was heating a liquid with some metal in it. It eventually came back on. There must be a thermal circuit breaker inside the unit. Yours may have a fuse or some sort of circuit breaker inside it, that needs replacing or resetting. Then again some units have a fuse that goes out when the Magnetron shorts out, or goes bad. This would require replacing the Magnetron as well as the fuse.

Unit not getting power


These machines seem prone to having a bad magnetron. Look for a circuit breaker near the power cord entry point. If tripped, reset and try to heat a cup of water. If it makes a loud buzz and then pops the breaker again, the consensus view is a bad magnetron. This is one repair that is recommended to send out. (~$150). You need to evaluate the probable cost vs a new machine.
