LG GR-382R - Ptc & Olp

6-2 PTC AND OLP
YES
NO
Normal operation of
Compressor is
impossible or poor.
Separates the PT
from Compressor and
measure the
resistance between
No. 5 and 6 (only
RSIR Type) or No. 4
and 5 of PTC with a
Tes ter or Wheatstone
Bridge (Figure 22).
Observation value is
220V/50Hz: 22 W ±30%
115V/60Hz: 6.8 W ±30%
240V/50Hz: 33 W ±30%
127,220V/60Hz:22 W ±30%
Check the other
electric components.
Separate the OLP
from Compressor and
check resistance value
between two terminals
of OLP with a Tester.
(Figure 23).
Replace PTC.
The Resistance value
is 0 or several
hundreds W
The value is ?
Check other electric
components.
Replace OLP
