Normal operation of
Compressor is
impossible or poor.

Separate the PTC-Starter
from Compressor and
measure the resistance
between No. 5 and 6 of
PTC-Starter with Tester or
Whistone Bridge(Figure 16).

Separate the OLP from
Compressor and check
resistance value between
two terminals of OLP with
Tester (Figure 17).

Observation value is

220V/50Hz : 33

Ω

No defrosting.

Poor cooling.

Position the Cam Shaft
to the point of first "click"
sound and check the current
flowing between terminals
No. 1(brown) and
No. 2(bright orange).
Next, position the Cam Shaft
to the point of second "click"
sound and check the current
flowing between terminals
No. 1(brown) and
No. 4(black).
(Figure 18).

Turn the Cam Shaft.

Shake about 3 times with
holding the Cam Shaft and
body softly.
