4 SIMPLE WAY OF H.V. INVERTER/MAGNETRON
TROUBLESHOOTING
Purpose:
Simple way
(3/37 seconds rule)
of identifying whether it’s Magnetron, Inverter, or others.
Set-up:
The unit under question is connected through the Ammeter as shown below.
Procedure:
Follow the matrix table below to identify the problem source.
Note:
Do not replace both Inverter board and Magnetron simultaneously and automatically without going through this
procedure.
Power will:
Ammeter reading is:
To do:
Remedy:
Shut off in 37 seconds
after “Start”.
1. Between 0.5A and 1.0A.
Check and repair open magnetron circuit Open magnetron wiring between Inverter
and magnetron terminal.
2. Between 1.0A and 2.0A.
Check continuity of D702 in Inverter PCB.
1. D702 shorted
Replace
