Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and also took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!

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 directions(+-). 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.

Our maytag microwaive sounded like a thrashing machine when running!

  • Customer: William from East Wenatchee WA

Over a period of a year or so, our over the stove microwaive oven started sounding like a thrashing machine every time we turned it on and got progressivly worse. The repair service wanted nearly half the cost of the appliance to just come out to take a look. I removed the oven from the wall cabinet, removed the cover and discovered that the cooling fan blade had come loose from the motor shaft and was hitting the casing. I ordered the fan motor assembly from you folks, replaced the faulty fan, and the problem was resolved at about one half of the cost of a service call.

Fan motor and magnetron did not come on, but every thing else did.

Problem would come and go. Found service schematic inside unit. Perform all the suggested tests. One possible solution was the primary interlock switch shown on the schematic and a check found the switch stuck. It would free up some times but would stick again in the open position. Ordered switch which was a simple plug in unit.

I thought that if I went one more time to visit my son, and the microwave tray was still gone (due to their having broken it), I would just order the part MYSELF!! So, that is what I had to do. They have been without this for at least 3-4 months........ Well, it was sitting at my door in less than 48 hours after I ordered it! Easy, easy, easy..........thank you!

1. Removed cabinet screws (10-15?). 2. Removed cabinet. 3. Removed top interlock switch which actually was not defective. The press clip connection appeared as if it had been arcing for quite some time and the corrosion created resistance sufficient to prevent the current from getting through the switch. 4. Replaced switch anyway but broke plastic retaining clip despite every effort not to do so. Reset broken clip with super glue. 5. Reassembled cabinet and appliance is in good working condition.
