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 21)
Separate the OLP from the
Compressor and check the
resistance value between
two terminals of OLP with
a Tester. (Figure 22)
