TROUBLE SHOOTING GUIDE
Following the procedures below to check if the oven is defective or not.
1. Check grounding before checking trouble.
2. Be careful of the high voltage circuit.
3. Discharge the high voltage capacitor.
4. When checking the continuity of the switches, fuse or high voltage transformer, disconnect one lead wire from these parts
and then check continuity with the AC plug removed. To do otherwise may result in a false reading or damage to your meter.
(TROUBLE 1) Door shut, timer set, but no cooking takes place.
D oes the fan m otor work w hen you
shut the door and turn the timer?
D oes the
fuse blow ?
C heck continuity of interlock
m onitor switch with door shut.
R eplace prim ary, secondary
interlock sw itch and interlock
m onitor switch.
R eplace fuse and check
continuity of both interlock
sw itch's contact and m onitor
sw itch's contact w ith door
partially open until monitor
sw itch contact.
R eplace prim ary, secondary
interlock sw itch and interlock
m onitor switch.
D isconnect one side of the
lead wire connected from
transform er to the high voltage
capacitor, and operate oven.
R eplace high
voltage
capacitor.
R eplace high
