3.
If the thermic protection (
1Q1
) does stay in the position
1
, check the winding of the compressor between
W1 & U2
–
V2 & U1-
V1 & W2
with digital multimeter and in case of infinity or 0 value change the compressor
.(picture1
without connection
)
Check the power supply (24) between
A1
and
A2
of the coil
1K5
with digital multimeter as electric wiring diagram of the
cooling unit
(picture 2)
5.
With power supply (24 V) between
A1
and
A2
of the coil
1K5
check the electric wiring
T12-T11
of the
Krivan
.(picture 3)
6.
If the electric wiring
T12-T11
are closed, probably the thermic protection of the compressor (krivan) is connected wait until

are closed and in the coil
1K5
there is no power supply,change the relay
1k5
.
