8.3. Troubleshooting of inverter circuit (U) and magnetron
This oven is programmed with a self diagnostics failure code system which will help for troubleshooting. H95, H97, H98 and H99
are the provided failure codes to indicate magnetron and inverter circuit problem areas. This section explains failure codes of H95,
H97, H98 and H99. First, you must program the DPC into TEST MODE, press Timer/Clock
pad twice
→
Press Start
pad once
→
press Power Level
pad once. Program unit for operation. H95, H97, H98, H99 appears in display window a short time after
[Start] pad is pressed and there is no microwave oscillation.
Alternate way to troubleshoot oven with AC Ampere meter used
H95, H97, H98, H99 appears in display window a short time after [Start] pad is pressed and no microwave oscillation with AC
Ampere meter used for troubleshooting.
