5. Screw must be tighten securely.
6. Install the heatsink onto the PCB by a screw and make
sure to apply extra solder between legs and PCB pattern
so that it's able to flow 15A or more main current.
7. Apply extra solder onto Q701 and Q702 legs and printed
foil pattern to be able to hold main large current of more
than 15A.
Service hint:
For easy removal of solder, apply some solder first than suck it
all.
8. How to test repaired Inverter PCB.
WARNING:
1. Do not test Inverter PCB with using any extention cable
Open gounding of inverter PCB is so DANGER.
2. Make sure to check no Bridge solder nor cold solder joint.
1. Install Inverter PCB into oven with screws securely, plug in
CN701, CN702 and CN703.
2. Insert AC plug through the Amper meter with specified
voltage.
NOTE: Current will be changed by the input AC voltage.
3. Operate the oven at High power setting for 1 minute.
4. Read
input
current
which
should
be
within
oven
specification.
NOTE: Input current will be decreased after a certain
cooking period.
5. Adjustment is not necessary when replacing transistors
You may adjust the preset volume control VR701 to meet
the specified input current when Transformer is replaced.
