Question about Whirlpool MH7140XF Microwave Oven
I have a whirlpool microwave that is mounted over a stove. It's model Number is MH1170XSS-0 . Up until last week it worked perfectly, NOW it wont heat anything. It seems to work perfectly, but reads "DEMO". I cannot figure out how to take it off DEMO mode.... WHAT DO I DO?
The manual says "while in standby mode, press and hold the '3' key on the keypad for 3 seconds until 2 tones sound and the 'DEMO' icon appears. Repeat to turn demo mode off."
You can download a copy of the manual here:
