MW4371G Samsung Microwave - Instructions

I ordered a microwave cooking tray from PartSelect; userfriendly site; and within two days, my part was delievered and easily installed. Thank you PartSelect!

replace new tray with no tools needed

none

Took out broken piece
Called GE Parts to order replacement
Upon arrival, opened package, took out new part, inserted it where old part had been.

Opened the microwave door and put the new plate on the carousel. Duh!

I ordered on tuesday right before Thanksgiving and was sick my tray plate broke with a house full of company comming for the holiday and no microwave low and behold i ordered on tuesday and it was at my door on wednesday what a shock i will forever be a loyal customer thanks part select!!!

Just placed the new tray in the microwave. Simple as that.

It was easy. went to GE website and click onto parts replacement. Placed my order and within three business days the new glass tray arrived. How easy was that....

Removed control panel, discharged HV capacitor. Removed old diode, tested to confirm failure. Replaced part. Other than the removal of the panel swapping the part was almost as easy as replacing a light bulb.

I removed the outer cover and exposed the inner workings. I watched a video on partselect.com to show how to remove and replace the Diode. I followed the instructions and it was very easy to replace.

Unfortunately, the diode was only part of the issue. I ended up replacing the High Voltage capacitor and Magnetron also. Those were a little more complicated but still easy to do.

Now the Microwave works just like new! Cost me less than $100 for all parts.

The high voltage tired was shorted. I replaced it with a new one, but that did not solve the problem.

You can test the high voltage tired with a voltmeter and a 9 V battery. Search Search for it on YouTube.

You can also test the high voltage capacitor, the high-voltage transformer, and the magnetron with a multi meter. Search for the procedures on YouTube.

I tested all these high-voltage components with a low-voltage multi meter, and they all checked out OK (after replacing the diode). However the microwave still did not heat food.

When working on a microwave it is important to unplug it and also discharge the high voltage capacitor. The capacitor has a 10 megaohm resister to automatically discharge itself, but it may have failed – – so discharge it manually.

In the end I ordered a new microwave.

Snipped four corners off inspection panel,removed one phillips screw and two elect. Connections. Reverse process.

Other tools that are usefull long needle nose pliers, long thin blade screw driver and small magnetic flashlight. Place the microwave on a work bench and remove the case it cover 3 sides. Place the microwave on a chair so it can stand with the controls up. You are replacing the lower door microswitch. The switch is located behind the control panel in the lower part of the area. The switch is several inches inside this area and your hands will not fit. Take care when moving wires and a couple of sensors. Use the thin blade screwdriver to release a tab holding the switch in place. Do not break this tab. Take the needle nose pliers and remove the switch. Put the wires on the new switch, open the door a short distance so a door lever moves enough to put the microswitch back into the bracket.

Just open door and install the new cooking tray in the grooves.

Pretty easy tear down and assembly once I removed it from cabinet (built in micro)
