Normal operation of
Compressor is
impossible or poor.
Separate the PTC-Starter
from Compressor and
measure the resistance
between No. 5 and 6 (only
RSIR type) or No. 4 and 5 of
PTC-Starter with a Tester or
Whistone Bridge.
(Figure 37)
Separate the OLP from the
Compressor and check the
resistance value between
two terminals of OLP with
a Tester. (Figure 38)
Observation value is
220V/50Hz : 22Ω±30%
115V/60Hz : 6.8Ω±30%
240V/50Hz : 33Ω±30%
127, 220V/60Hz : 22Ω
±30%
The resistance value is 0
or serveral hundreds Ω.
The value is ∞.
Check another
electric components.
Replace OLP.
Check another
electric
components.
Replace
PTC-Starter.
