The oven and grill don't even work
Expert:  KevinWhiteJA replied 6 days ago.

Thank you. This indicates an issue with the High voltage circuit of the appliance. I believe the magnetron is faulty and will need replacement. When you turn on the Microwave it starts and then magnetron kicks in however, if control detects magnetron has not started to heat it will turn itself off or even trip the circuit. When magnetron is faulty usually the Invert board is replaced as well. The parts are available for £121 (Magnetron)+ £127 (Power module) +repair charges (£99 if you book Siemens). Looking at the age of this appliance and cost of repair, it is better to buy new one then to spend this amount on repairs. Sorry about the bad news.
