Sadly your microwave has done it's last cooking. The mechanism you need to make it cook again would cost you more than a replacement microwave.

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

My magnatron went out on my 2003 model ge replaced the part but I had to pay the labor.Mine had a ten year warranty on parts.

yes the turn table turns, everything works, but no heat.

there are 2 fuses inmicrowave 1 for ac input 1 for high voltage transformer that will trigger the magnetron "for heating"

remedy;
uncrew the unit
replace fuse near the transformer this fuse.. usually enclose with plastic casing..
then test..


causes of blown fuse
improper ventilation

door micro switch open/need to replace / if that open the magnetron will not power no heat will produce.
