There are electrolytic filter capacitors on the control board which, due to age, can weaken, causing some bizarre results.

We've repaired several of these boards successfully, upgrading the capacitors and relays at the same time. It runs $39.95 and comes with a one-year guarantee.

They're the same as the Whirlpool RM286- and RM288-type models.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can also find helpful exploded views here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

How do I set the clock on a Panasonic microwave nn-e271wm

To set the clock, you need to press Timer/Clock twice. Then press the 10 Min keypad several times until you get to the correct hour. Then press the 1 Min keypad as needed to get to the closest 10 minute period below the current time. Finally press the 10 Sec keypad several times to reach the current time. Then press Timer/Clock once to exit the time set feature.

Panasonic has the manual for the NN-E271WM on their downloads page: http://www.panasonic.eu/Downloads/en_GB/popup.html . Enter the model number and then click View. You will need to accept the Panasonic Terms Of Use and click View again. The direct link to the manual is currently http://tda.panasonic-europe-service.com/docs/2z5845f124z3z39cabz656ez706466z25z9709ff8b3ba329b0c218b9bf248a6442e93022b3/tsn3/data/ALL/NNE281BMBPQ/OI/912715/NN-E271WME281BME281MM.pdf . See page 21 in the manual (23 in the PDF) to see the procedure.

I hope this helps.
