Question about Whirlpool GH7145XF Microwave Oven

1 Answer

GH7145XFB microwave hood

I have the above listed model that had a problem where it would lose power intermittently and then come on by itself. Lost power completely one time, took it down and brought it in for service and when they went to look at it at service, it was working again. Was cooking dinner the other day and had just heated up a cup of coffee, and when I went to do baked potatoes in the microwave, there was NO POWER to the unit at all. I cant get the inside light to come on, the digital display, the fan for the vent, etc. I have checked the outlet that it was plugged into and it works fine. I tried plugging it into other outlets and NO POWER to the unit still.

Is there some sort of in line fuse for the unit? Could it be the main power converter, etc? Any suggestions would be greatly appreciated as this is a great microwave--when it works correctly.

Thanks,

John

There is an internal fuse, and also a couple of thermostats, and I would be suspicious of the thermostat on or near the magnetron.

There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It helps with troubleshooting.

My frigidaire Gallery microwave model #FGMV174KFA will intermittently lose power completely. After a while, it will beep and come back on, giving a message "enjoy your oven." Right now I'm not enjoying...


There could be a connection problem in the electrical outlet the microwave is plugged into or anywhere in that circuit all the way back to your electric breaker panel. It sounds like the microwave is losing power and resetting. WARNING: Any type of electrical work should only be completed by persons qualified to do so.

The oven has no power. The outlet is hot. The unit will power up intermittently, but as soon as you try to turn it on it loses all power.


This is a safety feature of the microwave. Unplug it and leave the door open for about 10 minutes and it should work again with no problems.
P.S. My kids overheat mine all the time making pop corn.

Our GE Spacemaker Microwave (Model No. JVM1650) intermittently kicks off while heating and resets itself so that we have to reenter the time and date. Is this a Magnatron failure?


Saw something like this happen when a magnetron gasket was bad and Rf energy was interfering with the control board. Could also be a connection problem in the power circuit, acting like it was unplugged momentarily. Heavy draw from the High Voltage circuit when in cook mde. Eric

Kitchenaid microwave hood combo KHMS155LSS


First, do not leave this machine plugged in until it is serviced. If this is a KHMS155LSS, there is a very high probability that you have a keypad short. This defect can cause the machine to start on its own at ANYTIME; while you are on vacation or at work or at night while you are sleeping etc. Contact Whirlpool Customer Service and ask for Safety Dept immediately. They will most likely send A&E (Sears) out to fix it. Although they will fix the problem, if the keypad fails again, the underlying logic self start defect is still present. You should be under warranty if it is above model. Please be polite, insistent, but polite. With KitchenAid's pathetic quality in recent years, their customer service reps get more then an earful. Also, please go to the Consumer Product Safety Commision website at www.cpsc.gov and post a Report Unsafe Products report. This will help get this model recalled before someone loses their home or life. I almost had a fire this past Monday, Labor Day, 9/7/09 when my machine self started at 3 AM with a package of bacon left in it to thaw at room temp for the morning. What a smokey mess. Chinese made garbage. Shame on Whirlpool. Long live Hobart!, please buy back KitchenAid and bring back the lost quality.

Not certain of model # (built in micro/hood combo)


It may be that the magnetron is overheating and causing the magnetron thermostat to trip.

The fuse may be loose in its holder or may have loose end caps.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

The hot steam could have caused the microwave oven's thermostat to open. Or it may have gotten into the controls.

You should always use the vent or hood fan when boiling on the stove top.

Just stop working


A microwave can be dead for many reasons.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.
