SOURCE: Microwave does not heat

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

Here is a helpful link you or someone you know can use for test help, but read their safety warnings first:

Maytag microwave mmv4205bas key pad is not functioning properly

It could be that the buttons are worn out. You'd need to replace the keypad to fix it, which will likely cost about as much as a new microwave. See if you can get it fixed under warranty, also, try cycling the power, it's always worth a shot.

Easytronic deloghi microwave, all electrical functions working ok but does not warm food. please help

Please check the start button if its functional. The timer must be counting once you press the start button. Check also the air filter if it has dirt and dusts . Some ovens are equipped with sensors that disabled the unit once the air filter becomes dirty.

Microwave Display

Have you tried unplugging the unit for several minutes and then plugging it back in?

The oven's microprocessor receives the input commands from the front panel switches and it also drives the digital display.

Since the switches work and the oven works, the microprocessor appears to be functioning fine. I would say you have a defective display or a power supply issue that powers the display.

Unfortunately, you'll need to take it to be serviced.

Please let me know if I can be of further service to you.

Good luck!
