2. Faults
2-1. Power
Problems
No power on
outlet,
Fuse blows out.
Causes
- Power cordcut.
- Faultyconnectorinsertion.
• Faultyconnectionbetween 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 circuit 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 visuafiy.
- Check the input volt are with tester
(between power cord and products)
- Check the resistance
of power cord
with testerf (if it is 0_, it is shorted).
Measures
-Replace the components.
-Reconnect the connecting parts.
Reconnect
the connecting
parts.
;- Find and remove the cause of
problem(ex,
short, high voltage,
low voltage).
Replace with rated fuse.
Remarks
- Replace with rated
fuse after confirming
its specification.
- 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,
• If fuse blowns out
frequently, reconfirm
the cause and prevent.
