2. RELAY ASSY (PTC AND OLP)
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.
