Question about Whirlpool MH6140XK Microwave Oven

4 Answers

Is a Magnetron something I can replace myself?

My 3 year old unit stopped working - the repairman said teh magnetron was bad and the motor that rotates the tray was bad too (strange coincidence?)

Anyway, Whirlpool will give me teh Magnetron free and 50% off a motor so its only $35 - but the labor (including the $69 service call I allready paid for) will be close to $300! Well, a brand new unit at Lowe's is less than that.

So, I was thinking if they would send me the parts, is this something I could do myself? Or, at least find someone who can do it for less than $300? I will never buy whirlpool again, BTW!

    Thanks for discussing this issue. I looked up the cost of the magnatron AP3846818 and it is $91.94 and the motor is AP3846818 for $44.84. Both parts were not in supply and installation at home by a technician could run the bill up significantly.



    Ouch!!!!!!!! Will price counter top and use this one as a cabinet for storage.

    I have a new Over Range Whirlpool microwave Model MH1160XSQ-0 that is 24 months old with less than 24 hours of usage (I travel ALOT). Everything works as usual except the food stays cold. The troubleshooting guide is pointing to the magnetron not working. I see the part can be ordered, however I am wondering if diagrams are available and is this like a plug and go part replacement something I can do? I would be interested to know how many problems similar to mine exist. I just think it's quite odd the microwave has been used so little and this part goes out? Thaxs.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya: http://tinyurl.com/yzjozk

You can find helpful exploded view diagrams and order parts (if needed) by entering your full model number here: http://tinyurl.com/gv383

Also, Whirlpool models have a handy mini-manual inside behind the control panel keypad that is very useful.

If Whirlpool will actually send you the magnetron and motor (not to the servicer on your behalf) then you're really in luck. I'd be very surprised.

Had EXACT same symptoms on this model: Here is my solution-

***UNPLUG UNIT***
Take off the front vent (screws on top).
Take off the control panel (1 srew at top, then lift up and out). There are 3 switches that are activated by the door latches. The top switch has heavier wires going to it.(BTW There is a wiring diagram and troubleshooting packet in the bottom of the control panel) The top switch was faulty, which allowed everything to operate except the turntable and magnetron, and NO, they wouldn't coincidentally fail at the same exact time. YOU HAVE A BAD SWITCH. (Jerseyhelp, SOUNDS LIKE TECH EITHER MISSED THE BAD SWITCH OR IS TRYING TO RIP YOU OFF) You can order one at http://www.appliancepartspros.com/partsearch/model.aspx?model_id=266300 for about $10 (I followed link from THIS site, this is NOT my site)

You can also obtain this type of switch locally. Push back on the plastic tab holding the switch and it will swing up and out. Use needle nose pliers to pull on the connectors to remove the wires, NOT the wires themselves. I had a similar switch on hand that was rated at lower AMPS, so I put it in the bottom switch position (runs less current on that part of circuit) and moved the bottom switch to the top position. The middle switch is wired opposite the other 2, you cannot use it in the top or bottom position! stay out of the top cover and you will be relatively safe
as long as you keep the unit unplugged while working on it.

Hope this saves you a service call or purchase of a new unit. BTW my unit ran 7 years before failing. The switch had just gotten hot and eventually wore out, wouldn't even click when depressed. To ensure you get good contact on the replacement switch, crimp the connectors a bit with your pliers before installing on the switch. A loose connector will cause overheating (of the wire harness, not your popcorn) and poor operation

    Hi, I read your article/reply on fixYa regarding a whirlpool magnetron issue. It was very helpful, although, my turntable does work, just no heat. Do you think it is something I can fix myself? Micro only 2 yrs old :( Thanks, Heather

THE_JD is exactly right!
My microwave went out, no turntable and no magnetron operation.
I had already torn the microwave apart, looking for blown fuses, AND checking the switches, etc. I was just about to call a repairman to get an estimate on a new magnetron when I found this article.
After reading this I re-checked the switch with my Ohm-meter and there lay the problem.
I opened the switch and filed down the connectors and bent them over a little, and voila! Problem solved. Cost=$0. That switch wears out because it has higer voltage electricity going through the connectors and the arcing wears the connectors down.
Thanks!

    I was just wondering if any of you heard a band when the switch went out?

    If you hear a bang and the breaker tripped then you may need a capacitor, a microwave fuse, and possibly a magnetron. Make sure to look for wires that may have arced to the frame and or thermal cutoffs that may be no good while the case is open. I am a handyman and can repair such things with free parts salvaged out of disposed microwaves and cheap labour.

Without any known event, the microwave clocked no longer keeps time and the microwave does not heat up food. The timer works and the tray rotates, but no heating.


You have 2 systems inside your microwave, one is working, one is not.
The working one has the electric motor to drive the turntable and the timer.
The other system includes the "magnetron", which is the heavy unit that makes the microwaves to cook the food.
A repairman can check the magnetron to see if it has failed, and there are a few units that have a replaceable fuse that could be blown.
You will not want to try to fix it yourself, without a good knowledge of such things, as there is often a capacitor inside, which can shock you really bad if you touch it in error.
God bless your efforts.

Stopped heating


The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts, then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

Microwave stopped heating


I had the same oven for one and a half years and had the same problem. Had the sears repairman come out and he said the magnetron burned out and needed replacing for $285. It was never under warranty with the warranty that came with oven. I couldn't believe it! We had an independent repairman look at it and he found a design flaw that causes the magnetron to blow. If you replace the matnetron (megnatron?) it will work for awhile, maybe, but then just need to be replaced again. It's cheaper to buy a new microwave. In fact, I got out our old microwave that's over 20 yrs. old and still works--just isn't as fast and as new ovens. Good luck!

Carousel stopped turning


The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

Sanyo Microwave EM-G4775 - doesn't heat up......


It's probably a loose connection at the magnetron or a bad magnetron.

If it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

Some manufacturers (in the US anyway) will send you the magnetron to do it yourself. If nothing else, you can save about $75US by taking it to the shop yourself.

Apparently you're in the UK, judging by the model number.

Not working


HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Microwave dish/tray rotates intermittently.


If the turntable is not turning, you will get hot spots and uneven heating.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

Microwave not working, please suggest


Your magnetron tube has failed. According to the warranty on the Profile Series microwave ovens, the magnetron is covered for 5 years from the date of purchase, but labor is not included. I would call GE Customer Service and when they ask for the model number (which begins with JVM) and the serial number, be sure to give the date of purchase as the date you closed on your house. If they insist upon charging you for a service call and labor, I would call my builder's Customer Service Department and demand (very nicely) that they intervene with GE to waive the service and labor charges. That worked for me (Lennar Homes).

3 year old unit, oven works, microwave does not


hi,

You may need a new magnetron, contact sharp or the store you got it from; most microwaves have a 3-5 year warranty on the magnetron. If it's not in warranty, find a good appliance repairman, this is a difficult and dangerous repair job.

Does the turntable rotate? If everything but this works (except no heat), you probably have a bad door switch. Here's a discussion of what's involved in replacing it: http://www.fixya.com/support/t267796-kenmore_microwave_hood_combination_over

If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
