That sounds like it would be a 220V 50Hz model. I would assume you're using it with the correct power source or if needed, the right power transformer and/or adapters. I'm curious how you solved the touchpad control problem? When troubleshooting, I always first check an area that was worked on before if I know about it. That being said, the most common causes of the problem you describe are: - defective door switch (probably the upper one) - defective door switch mount - loose and tarnished connection at the FA terminal of the magnetron (disconnect, tighten, burnish, and reinstall) If you have sufficient experience and/or information, you can do it yourself, but I a microwave uses and produces voltages that can be instantly lethal. These areas can be safely checked if the oven is disconnected from the wall and the high voltage capacitor is properly discharged. Information on discharging the capacitor and testing these parts is available from various sources on the Web. Door switches can be obtained from a local appliance parts store. Good luck and be safe.

How do I get the heat to work?

Hi Marc, there is no 'heat' per say with microwave ovens as one would find in a convection oven. Microwave ovens operate by generating electromagnetic fields (within the microwave band) that causes water molecules in the food item to vibrate/rotate creating friction/heat - within the food item as opposed to the surrounding space (this would be convection)

Sharp microwave r95stm not heating

This a common problem, the likely cause is a bad magnetron "heats food" and is the heart of the microwave oven, if the item is five years or more, cheaper to replace.

Sharp R-340H Microwave has power but does not heat food. Carousel working.

The magnetron is the likely problem, "heats food" the other two items to check is the high voltage capacitor and diode. It usually is cheaper to replace.

My delonghi 800w microwave oven works but does not heat up food

If your handy with getting the cover off and looking inside... check the obvious.
I suspect :
If both microwave and Heating elements dont work, then I will assume the magnetron is ok, ans we are dealing with a high voltage issue... and you will need at best... a volt meter and or neon troublelight...
moust appliances have a simple schematic inside... I would start with the heating element first... trace wiring back to circuit board... usually one side of the heating element is connected to the white wire (neutral) and live (Hot) side is controlled thru the circuit board... so finding the neutral should be easy... then trace with neon light or voltmeter...

I know easy for me to say... but with everything else working... it doesnt seem to be the microprocessor that controlls the unit...

Btw, I’m available to help over the phone in case u need at

My microwave sounds like its working but is not heating food

More than likely, what has failed is called a "Magnitron" and you can find them online and replace, you may have to take your unit out verify what model it is, and sizes. but yes fixable.
