After punching in settings and time and hit start i have to hit side of the microwave to make it work
For model number PVM1870SM3SS
Hello and thank you for writing.
It certainly sounds like it could be faulty or lose door switches PS237421 and PS237422 you should check the part(s) for signs of damage or test with a multimeter, and replace the part(s) as needed. It is recommended to replace both parts at the same time. We hope this helps. Please contact us anytime if you require further assistance.
GE profile microwave went dead while heating up a sweet potato. Had the unit for years.In your diagram, it shows 1 line fuse, but there are actually 2 fuses there when i take off the touchpad.
question: is the other fuse a spare or does the unit need 2?
i interchanged both of them and the unit still does not work.
i also bought 2 microwave fuses from home depot, but that didn't work either.
thank you.

Hello Russell, thank you for your question. Usually there is just one of each of the in line fuse, a thermostat and a diode in microwaves. If there are 2 line fuses in your unit we would recommend replacing them both. The other parts that could cause the unit to go dead are the Part #: PS239525 diode, Part #: PS239811 Thermal fuse. All three parts can be tested with a multimeter to determine if they are faulty or not. I hope this helps!

My fan turns on when I shut the door
For model number PVM1870SM3SS
Hello Duane, thank you for reaching out. Usually, this problem is caused by faulty door interlock switches or door switch operating latches. We recommend you replace the micro switch, part number PS237035, to fix the issue. We hope this solves your problem!
When you open the microwave door the microwave starts running by itself. It shuts off when you close the door. It turns back on when you open the door again. Tried unplugging and plugging back in but that did not help. Any ideas?
For model number PVM1870SM3SS
Hello, Thank you for your question. Looking at your model number you will need to replace this door switch- PartSelect Number: PS237421. This is the switch that stops the unit from running when the door it open. We hope this helps.

Turned out the issue was easily solved by replacing a single, inexpensive fuse.
First off, UNPLUG THE MICROWAVE.
The fuse is located under the plastic grill at the top of the microwave. It's held on by two screws. Once you've removed the screws and taken off the plastic grill, you go to the right side of the mic
... Read morerowave and remove another screw that holds a small metal grill in place. Removing the small metal grill is probably the toughest part of this repair. You kind of have to rock it back and forth a bit to get it to release. Once that's off, you can get to the fuse. I removed the burnt out one with a pair of needle nose pliers. I also put a small piece of cardboard under the fuse when I did this so I didn't accidentally drop it into the innards of the microwave. I did the same thing when I replaced the new fuse. I then plugged the appliance back in and made sure it worked. Once that was confirmed, I replaced both grills.
Noted on partselect.com that someone else with this problem, found it to be secondary door switch. There are three door switches in this model, but online info noted that one of the three might feel "soft" (in my case, one switch clicked in a rather "jiggly" way, the other two were strong decisive clicks.) To access the door switches on
... Read more this model was the only difficult part. First use a torx bit to remove the two torx screws below the latches inside the microwave. This frees the latching part inside, that holds the door switches, which you will remove after you take off the control panel. The top grill has to come off before you can remove the door panel. Remove the screws above the grill, on the microwave top cover, The grill on this model is covered with a panel that moves out when it vents. After removing the two top screws, the covered grill vent slides left to remove. Be careful, as the sliding tabs are plastic. Wiggle and jiggle it, to slip it off. Below the removed grill, is a small metal grill with one screw in lower center. Remove that screw, and wiggle that out. You'll then see the one screw that holds on the control panel. Remove this screw, and lift the control panel up to remove. Again, go slowly and gently, as the bottom tabs holding the control panel in, are also plastic and easily broken. Lay the control panel on something, (I used the coffee maker) and pull out the wire bundles tucked on the left, that are attached to the latching panel. Wiggle the latching panel gently to lift it up off of it's plastic tabs and pull it out towards you, so you can see the three door switches. Each switch (part number WB24X829) has a little black switch on it. Feel each switch with either your finger, or a screwdriver to see which one doesn't "click" strongly. The weak one is the one you will replace. The door switches are fitted into a tab, and plugged into their wires. Remove the defective switch, pull out the wires, and replace it with the new switch, plugging back the wires, and slipping it back into it's plastic tabs. Then put everything back together in reverse order. The entire job took me fifteen minutes EXCEPT for figuring out how to slide off the upper grill, which I have told you. A repairman would have cost $150, the part was $18. AND, there's a good chance, the other two switches will get "used up" in the next year or so as well, so I'll be ready next time. Thank you, Partselect, why work all day, to make money, only to give it to somebody else, for fifteen minutes of work. All I needed was the knowledge.
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 connec
... Read moretor 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.
