LG GR-282MF - PTC and OLP; Defrost Timer

6-2 PTC AND OLP
Normal operation of
Compressor is
impossible or poor.
Separate the PTC
from Compressor and
measure the
resistance between
No. 5 and 6 of PTC
with a Tester or
Whistone Bridge.
(Figure 24)
Separate the OLP
from Compressor and
check resistance
value between two
terminals of OLP with
a Tester. (Figure 25)
Observation value is
220V/50Hz : 22§ +30%
115V/60Hz : 6.8§ +30%
240V/50Hz : 33§ +30%
127, 220V/60Hz :
