8.2. Troubleshooting of inverter circuit (U) and magnetron NEW H.V.

This oven is programmed with a self diagnostics failure code system which will help for troubleshooting. H97, H98, and H99 are the
provided failure codes to indicate magnetron and inverter circuit problem areas. This section explains failure codes of H97, H98,
and H99. First, you must program the DPC by pressing Clock

, Timer , Start , Power Level . Program unit for operation. H97,

H98, H99 appears in display window a short time after start key is pressed and there is no microwave oscillation.

Alternate way to troubleshoot oven with AC Ampere meter used
