Question about Jenn-Air M439 Microwave Oven

1 Answer

Most of the LED display is inop

I have a Sharp R-1405 over-the-range microwave. Most of the LED elements on the display are out, probably from cooking steam getting into the unit. Is it the display itself, or the control board? Also, what's the part number for each so I can order a replacement?
Thank you.

    Sir,

    The complete model number as indicated on the sticker, and in the owner's manual, is R-1405.

    Thank you for your help.

    I cannot see the oven temp because the LED display is so dim. The clock LED works fine, right next to it. Help!

MICROWAVE OVEN MODEL R-1405 THE INDICATOR NUMBERS ON FRONT PANEL DO NOT WORK WHAT DO I NEED TO FIX PROBLEM?


A faily common problem. You need a new display panel to fix that. The display panel comes separate from the control board.

The display no longer lights up


VFDs (vacuum fluorescent displays) are tricky, most likely you are looking at replacing the entire board. This contains the display and the entry key plus their logic. If you open it up check the connections for cold soldier joints, beyond that it's probably time for a new oven, much cheaper!

Noisy microwave not cooking


Is it making a louder than usual; buzz or hum when you try to cook?

If so, I would suspect a shorted high voltage diode ore a bad magnetron.
