no heat
this problem started two months ago when my micro quit heating up, after all the research most agreed it was the magnetron. taking the micowave apart is not to difficult just make sure you bag all the screws accordingly. the high voltage area is on the right hand side behind a panel. caution there is a capacitor that will bite if your not

careful, need to short the circuit between the two connectors with an insulated screw driver it will make a small pop or let it sit for awhile and it will discharge by itself. The magnetron worked for two days then quit, after more research i took it apart again and tightened up all the connections. Worked great on the bench but when i got it back up on the cabinet two dayslater kaput again. so again i take it down and replaced the two cheapest parts in the high voltage system, magnetron thermst fix, and h.v diode. benched tested it this time for 3 days cooking anything that i could think of, worked great. its been one week now afer installtion and it is still working.

This magnetron in your microwave creates the radiation needed for cooking or warming your food. It is located inside the main cavity, typically near the transformer or waveguide. When the magnetron becomes defective, your food may not heat up properly or heat up at all. Additionally, buzzing or humming sounds may be noticeable while the microwave is in operation. With a malfunctioning magnetron, your microwave loses its primary function. To remove it, you first need to unplug your microwave from its outlet. Before touching any components, discharge the capacitor by placing a screwdriver, with an insulated handle, across the two terminals of the capacitor. Once the capacitor is discharged, replace the current magnetron by disconnecting it from any wires and removing any mounting screws or clips. This magnetron is sold individually and is supplied directly from the original equipment manufacturer.

This authentic high-voltage capacitor stores and supplies electrical energy to the magnetron so that your microwave can heat up your food. It is a cylindrical component located inside the control area of the microwave. If the capacitor malfunctions, you may hear buzzing or humming noises, witness sparks or arcing inside the microwave, or experience inconsistent or no heating of your food. As microwaves use high voltage, exercise extreme caution during the repair process to avoid injury. Even when unplugged, the capacitor retains a significant electrical charge. To replace it, start by unplugging the microwave and removing the glass turntable and support before proceeding. Refer to the user guide for instructions on accessing the capacitor within the cabinet. Discharge the capacitor by creating a short circuit between each terminal and between each terminal and the chassis. Do so by using a pair of insulated-handle needle-nose pliers to simultaneously touch both terminals. Alternatively, you can use a well-insulated screwdriver, touching one terminal and gently sliding it forward to the other terminal, holding it there for a few seconds. Avoid touching the metal part of the tool and be aware that this can result in a loud and startling popping sound. Once discharged, you can safely disconnect the wires and remove the mounting fasteners. Please note that this OEM replacement part is sold individually.

Sparks and loud hum from oven
1. I went to the internet to find the service manual for the Maytag microwave.
2. I opened up the oven and started measuring the resistance of the diode, capacitor, transformer, and magnetron between terminals and then to ground. The transformer and magnetron were well within the resistance limits. The diode was shorted in both direc ... Read more tions(+-). The capacitor was fully open in both directions -- high resistance.
3. I ordered the 2 parts, installed them, and ran the oven. Worked perfect first time.
4. Reinstalled oven and worked ever since (1 week so far).
5. The secret was that the transformer had a load hum. I figured the transformer was OK. The magnetron had no short between filaments and ground to filaments. The only two left were the diode and capacitor. The first two are about $200 -- almost the value of a new microwave. The $70 repair was well worth it. If the first two were still bad, then tempted to buy a new oven.

My microwave began suddenly making a loud humming noise while cooking food.
My microwave began suddenly making a loud harsh humming noise while cooking food. I did not let it go on long enough to know if it cooked the food or not. I did some Internet research and learned that it was likely the Magnetron. The test for this was to run the microwave for at least a minute on the lowest power setting and see if the no

ise cycled on and off. It did, so I (actually, my wife) ordered the part from partselect.com using the model number. I was successful in replacing the part, and we are back to microwave popcorn and quick defrost for a price that was less than a service call, however, it was time consuming, required a large work area, and access to 5 out of 6 sides of the unit. So proceed at your own discretion
Caution:
The first thing in every set of repair instructions was to discharge (short-circuit) the capacitor, as it may store large (as in lethal) amounts of electricity even when it is not connected to a power source. I had never done this, but found these instructions:
“Discharging your microwave's capacitor is absolutely essential in preventing injury to your microwave, your tools, and yourself. A capacitor stores a large amount of electricity even when your microwave is unplugged, and it must be discharged before beginning any repair.
A capacitor is discharged by creating a short circuit between each of the two capacitor terminals, and between each terminal and the chassis. The chassis is the metal mounting (bare metal surface) of the capacitor. Read these directions thoroughly before you proceed.
With your microwave unit unplugged, touch the blade of a well insulated screwdriver to one terminal. Gently slide the screwdriver forward until it reaches the other terminal, holding it there for a few seconds. Be aware that this often results in a loud and startling 'POP'.
Repeat this procedure in order to create a short circuit between each capacitor terminal and the chassis (bare metal mounting plate surface). This same method can be applied to a capacitor having three, and not two, terminals.”
I had not run my microwave in over a week, and then while my part was shipping, left my microwave 'unplugged' for more than two days, and my capacitor apparently discharged itself, although I did go through the above procedure carefully and completely - just in case.
Step-By-Step:
1. You must remove your microwave from the cabinets - it is impossible to repair otherwise. This is best accomplished with 2 strong people - my wife and I made it work, but wished for another guy.
a. While supporting the microwave, remove the two screws coming down through the cabinet above.
b. Lift the rear of the microwave as much as possible, then tilt the front down - there is a clip high on the left side, as well as the hinge/clips on the bottom.
c. If you do not lift it off the wall all at once, you may have to lift the rear even farther to remove it from the hinge/clips on the bottom.
Important Note: Always beware of the microwave door, if it is bent or broken and cannot retain a seal, the microwave not function as a safety feature to keep from releasing microwaves.
2. Remove the vent cover on the top/front of the microwave - be careful, it's plastic.
3. Remove the vent cover and light panel on the bottom of the microwave - this is several screws and some simple wire clips.
4. Remove the "shell" (top and sides) of the microwave - this is several more screws on the back. Make sure to remove the plate that is holding the cord in place on the top.
5. Remove the interface panel by the screws on the top (which had been hidden by the vent cover) - the wires can remain attached, just slide it aside.
6. Remove the metal cover on the right side at the rear; this will expose the Magnetron and the Capacitor. Remember to immediately test and discharge the capacitor!
7. After you discharge the capacitor, remove the other cover plate and the support bracket - in case you haven't noticed, this is a time and space consuming operation.
