2. Faults
2-1. Power
Problems
No power on
outlet.
Fuse blows out.
Causes
- Power cord cut.
- Faulty connector
insertion.
- Faulty connection
between plug
and adapter.
- Short circuit by wrong connection.
- Low voltage products are
connected to high voltage.
- Short circuit by insects.
. Electricity leakage.
- High voltage.
. Short cimuit of components
(tracking due to moisture and dust
penetration).
Checks
- Check the voltage with tester.
Check visually.
- Check visually.
- Check the fuse with tester
or visually.
- Check the input volt are with tester
(between power cord and products)
- Check the resistance of power cord
with tested (if it is 0_;;_, i t is shorted).
•easures
-Replace the components.
-Reconnect
the connecting parts.
- Reconnect the connecting parts.
- Find and remove the cause of
probtam(ex, short, high voltage,
low voltage).
- Replace with rated fuse.
2-2.
Compressor
Problems
Compressor
- Faulty PTC.
does not
operate,
Causes
- Compressor
is frozen,
Checks
- Check the resistance.
Vlaue:_o is defective,
- If compressor
assembly parts are
normal(capacitor,
PTC, OLP),
apply power directly to the
compressor
to force operation.
(_
Auxiliary winding __
OLP
It starts as soon as it is
contacted.
•easures
- If resistance is infinite, replace it
with new one.
- If it is not infinite, it is normal,
- Check other parts.
- During forced operation:
- Operates: Check other parts.
- Not operate: Replace the frozen
compressor
with new one, weld,
evacuate, and recharge refrigerant.
• Refer to weld repair procedures.
Remarks
- Replace with rated
fuse after confirming
its specification.
• If fuse blowns out
frequently,
reconfirm
the cause and prevent.
