Panasonic NN-CT8905 Error code H97
« on: September 29, 2014,09:40:35 »
Hi folks,

Got and fitted a new identical inverter board to find on powering up, nothing much happened apart from a little rattling noise, and error code H97 was displayed.

I always use a moving iron ammeter with microwaves to see how things are going and current indicated was negligible.

Gather H97 usually indicates that the magnetron filament is O/C or there are loose wires about. Checked and filament is OK with no loose wires.

Guess Magnetron may be duff and caused the first inverter to pop - Any thoughts ? - Thanks - Chris.
