Microwave not heating anything? everything else work

Judging from the model and without looking it up I expect that unit has an inverter. If it is not the Switches and you have replaced the mag, the inverter is the power supply for the mag to work so either mag not getting power from inverter or inverter not getting signals from main PCB Timer board.

Same thing has happened to me. My brother in law seems to think it cant be fixed. Bought it Dec 2008 so no warranty.

Were you able to get anythihng out of morphy richards?

I just had the exact same problem. :( Did you find anything out?

The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

Hello t_sumner4756,
Everything else can work perfectly fine but if it doesn't generate microwaves to heat your food than it is not working ( you knew that anyway).. Unfortunately, and in most cases when you microwave stops working in that manner..the components at fault are either the Magnetron, Filament PS or a High Voltage Capacitor..What that means is that you are probably better off just replacing the entire appliance rather than attempting to repair it. If it is a year old or less, bring it back to where you purchased it and have them replace it.. I am sure that is not what you wanted to hear but when the cost to repair exceeds the cost to replace... it just isn't worth repairing.. Plus.. there is an element of danger associated with these kinds of repairs...
Regards,
Rick

In most cases, this is a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here.

We're happy to help and we appreciate your thoughtful rating of our answer.

at highvoltage section wiring may bae problem, check wiring and connectrors of magnetron and capacitor and transformer.

check magnetron, and related circuit...
