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
(only RSIR Type) or No.
4 and 5 of PTC with a
Tester or Wheat stone
bridge. (Figure 22)
Separate the OLP from
Compressor and check
resistance value
between two terminals
of OLP with a Tester.
