Carousel tray drive coupler broke

  • Customer: BRIAN from PERRY OK
  • Difficulty: Easy
  • Time to Complete: Less than 15 mins
  • Tools Required: Screw drivers
  • 27 of 34 people found this instruction helpful
This coupler has a tab on it that keeps you from being able to push it straight down onto the motor from the inside of the microwave.
Turn off the breaker to the microwave or unplug it. Remove five screws that hold the bottom cover of the microwave. The cover will hinge down and hang on tabs at the back.
Unplug the wire connector on the drive motor by pulling it straight off. Remove one screw that locks the drive motor in place. Turn the motor slightly to unlatch it from its mounting tabs.
Place the new coupler into the opening inside the microwave. While holding/turning the coupling with one hand, insert the motor shaft into the coupling. It will only fit one way. Press the motor and coupling together until the motor can be latched into its mounting tabs. Secure motor with screw and install bottom cover.

Take 2 screws off on top of the microwave, remove the small grill, remove the old charcoal filter, replace it with the new one put the grill back on, that is it, very easy. I change the filter every 6 months.

Turntable won't move, no heat -but light and fan ok.

  • Customer: Sean from San Jose CA
  • Difficulty: A Bit Difficult
  • Time to Complete: 15 - 30 mins
  • Tools Required: Screw drivers
  • 19 of 22 people found this instruction helpful
Remove the 2 Torx-15 screws at left of control panel. Work the control panel out by pulling slightly to the left first - it is engaged to the slotted holes to the right.

Remove the door's upper switch by lifting the tab and pulling out the switch carefully. To install the new switch, you may have to remove 2 philips screws holding the plastic assembly where the switches are mounted to the metal frame.

Diagrams on the website are misleading b/c the switch shown up on top of the other 2 switches is the switch w/ the NC (upper) terminal while you'll need the NO (lower) terminal for this repair (symptoms are: turntable won't move, no heat -but light and fan ok). I should have called before ordering the part (had to pay shipping twice)...

Once I got the right part, it works just like before.

This lamp does not have easy access

  • Customer: Walter from Midvale UT
  • Difficulty: A Bit Difficult
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers

This is the second time that this lamp hase gone out. It is located in a small space in the top of the microwave and you need to remove the top front pannel, then take a screw or two out of a metal shield and bend the shield up to get your hand into the compartment where, if you know how, you can reach in and lift out the reflector shield that the lighbulb is plugged into and remove the old one and plug in the new one. The first time was hard to figure out how to do it but the second time wasn't bad because I knew how to do it.

Glass turn table made loud noise while turning then stopped turning

This repair could not have been easier! The website was great at helping to identify the problem and the part needed. Users discribing how they did the repair gave me the confidence to do it myself. I got the part the day after I ordered it, installed it and my microwave was a good as new! It was as simple as unscrewing seven screws to remove the bottom of the microwave. Then two more screws to remove the part. Unplug the broken drive, plug in the new one and screw everything back together! Don't forget to unplug your microwave before you begin.

Great website!

All electircal functions worked except the heating mechanism

A great place to start is to reveiw the posting from "Marla From Arlington TX" posted on 8-3-09. It provides an excellent description of the process that you will need to follow. The only additional thing that I would add is to check the contacts on the switches. In my case I found that all three of the switches had a small build-up of corrosion. I used sandpaper to clean the contacts. Because none of the switches had a "soft" click to them, it was hard to identify the bad one. I basically picked the worse looking one and then cleaned the contacts of the other two. I'm not sure if I actually even had a bad switch or if they all just needed cleaning. Whatever the case, it worked. I would suggest checking the contacts first. You may get away with not having to replace any of the switches. And in my case what makes me think that it may have just simply been dirty contacts is that the heating mechanism would engage every now and then. It wasn't dead 100 percent of the time. It's worth a try anyway.

First, I waste $65 by calling some "REPAIR" service. They showed at home and charge me that just to tell me
Second, I researched on the web and ordered a part, which was not the issue. I waste abnother $72
Third, I found Part-Select and got the right answer: the Diode was the problem. Ordered the part form Part-Select and it FIxed it !!!

Note: I did not buy a new microwave because this one is mounted on the wall and it will cost me +$800 just the lowest price.

Microwave Fan Turned on When Door Was Opened

  • Customer: Bishop from Coupland TX
  • Difficulty: Easy
  • Time to Complete: 30 - 60 mins
  • Tools Required: Screw drivers

To get to the switches you need to remove the metal cover/housing of the microwave, by first removing several screws that hold it in place, and then sliding the cover towards the back of the unit. You'll find the switches in some plastic holders above the door-open button, and it's its easy to see how the mechanism engages/disengages the switches when the door is opened and closed.

If it is not obvious which switch is bad, in our case the bad switch felt "soft" when we pressed the switch button with our fingers. A good switch has a firm "click" when pressed.

The switches are easy to replace - pop out the old switch (no tools required) and pull off the electrical connectors. Then pop in the new switch and reattach the connectors.

No heat in the microwave

We purchased our Microhood oven about 4 years ago along with the extended warranty package offered thru home depot. Within one year, the problems began. Each year the secondary switch would go bad rendering the microwave useless. If you have 3 small children like we do, you tend to use it a lot. We sure take the microwave for granted.

Each time G.E. would fix the problem at no charge. Ths time - the warranty had expired and GE wanted to charge us $80.00 for service call plus parts and labor. We estimated the cost to run at least $150.00 or more.

To top it all off, GE was going to have a service tech avail for over 2 weeks. This is poor customer service and completely unaccceptable.

Because this was a recurring problem, I figured it was the same part that had being going bad since we purchased the appliance. I decided to order the part "secondary switch" myself and attempt to fix the microwave on my own.

I ordered the part last Tuesday, the part arrived last Friday. Within 10 minutes I had the microwave apart, replaced the part and had the microwave back in working order.

PartSelect saved me over $100.00.

We are very satified with PartsSelect, I would recommend them to anyone

I looked up the parts of the microwave on Part Select to see if there might be something I might be able to do myself. I found that the Cooking Tray drive motor was the problem. I ordered the part and got it the very next day. I loosened the 6 screws to the lower part of the microwave and then the two screws that held the part in place. I removed the element and pulled the wire plug from the element, placed the new element back in with the screws, repluged the wire, placed the lower cover back to the microwave, tested the microwave out and, is still working quietly as if it were new. Thanks to part select.com it was easy.

rotating glass tray was grinding and not turning.

I first took the filters of the exhaust and then removed the screws on the bottom of the combination microware hood fan. Once the 6 retention phillips head screws were removed from the bottom of the microwave, and the hinged bottom "door" lowered the motor was exposed. I removed the motor by removing the two phillips screws and unplugged the motor. The hardest part was finding a replacement on the net because most shops did not give enough details or pictures to know if a part was exchangable or a replacement. Partselect.com listed the parts, motor voltage, and had pictures so that I was comfortable with ordering. The part arrived the day it was scheduled to and I simple reversed the process and within 5 minutes I had the microwave motor in and back together. It is nice to do business with a place that also gives you a returns policy upfront.
