Oven shuts down after approximately 15 -33 seconds.

If the microwave shuts down after a short time in micropower mode, conduct the following test.

The microwave oven must be set in test mode to activate the self diagnostic failure code system.

SELF TEST MODE

When oven is set in test mode place water load in oven, set micropower to high and time to one minute, press start.

H97, H98 appears in display window a short time after start pad is pressed and there is no microwave oscillation.
