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.

If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

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

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.

My microwave turns completely off... Touch pad and lights inside... I have to wait 10 seconds to 10 minutes and then it turns back on and will ask if you want to set the clock. Sometimes it will let me...


Hi Ben,
This has got to be an intermittent power to the control PCB problem. The control board asking to set the clock means that the CPU has been reset by losing power. First, make sure that the problem is not the outlet by plugging in a small lamp or digital clock to see if it works intermittently or resets. Leave it plugged in for at least 24 hours.
(If using a lamp, put in a small 20 watt light bulb or CFL).
It could also be a bad connection to or at the fuse holder in the microwave oven. If all of the wiring and connections look good, it's most likely a bad connection on the control PCB probably around the transformer on the board. Be careful.......

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.

My fridgidaire microwave just completely lost all power out of the blue. Could it be a blown fuse in the microwave itself?


Hello,
It very well could be a blown fuse. I assume you checked power at the plug and checked the breaker. Also I assume and over the range micro. To get to the fuse you need remove the grille above the door then you should see a screw holding the control panel in place. Remove that screw and tip the panel out and you should see the fuse ( sometimes two) just inside the cabinet. remember to unplug or turn off the breaker before doing any repairs. you can goto - http://www.searspartsdirect.com/partsdirect/index.action - to find a parts breakdown and order parts. Good Luck

hi,
The F2 code is a keyboard failure. Since it's intermittent I would check for a loose wire/connection. open the control panel and reset the ribbon cable on the circuit board....

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

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.

It completely shuts off after 3 or 5 seconds of operation, it happens on all cooking times and power levels. no matter if the vent fan or light is on or off. The failure is intermittent and started like a...


Sadly, we hear of this over and over.

This is usually due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

GE had a campaign (but not a recall, mind you!) covering several models.

Details are in their bulletin at http://207.234.249.73/mwd/ge_mw_mag_kit_bulletin.pdf

Even if your model is not on the list, the same problem can occur, requiring a kit. I just think the difference is that GE has stopped paying for the repairs.

The parts kit (that GE used to pay for) is part # WB27X10489 and is shown here: http://207.234.249.73/mwd/wb27x10489_ge_mag_stir_kit.jpg
