Normal operation of
Compressor is
impossible or poor.
Separate the Relay Assy
from Compressor and
measure the resistance
between M and S with a
Tester or Whistone Bridge.
(Figure 21)
Separate the Relay Assy
from the Compressor and
check the resistance value
between two terminals of
OLP with a Tester.
(Figure 22)
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 ∞ .
