Tim Gray June 01, 2017 for Model Number WMH1162XVQ3 my microwave is arcing from my diode wire to metal frame?
1 Answer Tim, replace the diode, make sure when you attach the eyelet end to the cabinet frame, sand the area around the screw, and make sure everything is good and tight as possible. Also check and make sure there are no bare metal spots or arc marks on the cabinet frame or area, if there are make sure you touch up the areas with T/U paint. You also want to Carefully test or replace the capacitor. Read More...
Hugo E November 13, 2016 for Model Number WMH32519CB MICROWAVE, WHIRLPOOL Can't get your system to locate the magnetron part and price. Do you stock it?
Kim August 27, 2016 for Model Number MH8150XJB-1 Hi, I'm trying to find the location of the diode and determine if I must remove the unit from the cabinet to access it. I've removed the control panel and per a video looked to remove the metal plate above but it does not appear to be removable. According to the Tech Sheet, it appears the diode sits behind the cooling fan motor with the magnetron above it. Any suggestions on accessing the diode? Thanks!
1 Answer Kim, In order to replace the diode you will need to pull the unit down from installation and remove the cabinet. Once the cabinet of the unit has been removed the diode will be coming off of the capacitor. There may be a plate that would have to come off to access it on the right side but may be able to see it from the top. Read More...
Randy August 11, 2015 for Model Number MH3184XPB0 I have a Whirlpool MH3184XP microwave that does not heat. The last time I used it, I heard a loud crack (high voltage arc to ground?) a few seconds after I pressed run. All other operations (e.g. ventilation fan, control panel, turntable, underhood lights, etc.) seem to be working, just no heat. I tested the capacitor which seems OK. I understand it could be the diode. Where is this diode located? It is not in plain sight when I look behind the control panel.
1 Answer Hello Randy. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the transformer should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. All of these are +- 10%. If all the readings are proper and in range, replace the magnetron. The diode W11256462 goes from the capacitor to the frame of the unit. Read More...
Benny July 20, 2015 Where is a power diode located on a Maytag undercounter microwave. How do I replace it?
1 Answer Benny, If you unplug the unit and pull the unit down from installation. You will then need to pull the cabinet off the unit and discharge the capacitor. The diode is connected to the capacitor and screws to the base of the unit. Read More...
George February 28, 2014 for Model Number Maytag, made by Whirlpool, microwave Hello, my microwave starts and runs, but makes a loud humming noise and will not heat. I think it is the Diod. it reads 4.9 both ways on my ohm meter. I know it should only read one way, but I thought if it was bad it would read open in one direction. Do you think my diod is bad.

Mark February 14, 2014 for Model Number Emerson MW 8997B microwave oven I'm trying to find a replacement diode for this microwave Emerson MW8997B; diode #RG803. The search turns up 8 pages of diodes - but doesn't tell me which ones are actually appropriate for this model. How are diodes rated? amps? I don't want to buy one if its just going to burn up after one bowl of soup. Thanks.
1 Answer Hello Mark! Unfortunately, we do not carry parts for the brand Emerson and are unable to verify the correct replacement diode needed. Sorry about that! Read More...
John October 16, 2013 for Model Number 66568611991 What is involved in changing the magnetron bulb and the diode? Do l have to remove the microwave from the wall?
1 Answer Hello John. Yes, you will need to remove the microwave from the wall to access and replace the parts. You will disconnect the power and remove the outer cover off the unit. The be careful and discharge the capacitor on the unit. Now it is safe to remove the magnetron and diode from the unit and install the new parts. Make sure you discharge the capacitor first.
