4.13.1. Electric chain of coupling of the compressor of the air conditioner

GENERAL INFORMATION

Contacts of the relay of the compressor of the air conditioner

1. To the power control unit
2. To coupling of the compressor
3. Accumulator tension
4. It is not used
5. Accumulator tension
6. Grounding

Press the button of the air conditioner and check as coupling of the compressor works. If coupling does not work, remove the switch of pressure of air conditioning system and close its contacts by a crossing point. If now coupling works, so pressure in system too low or too high and system needs to be examined in a specialized workshop.

If coupling still does not work, check whether tension on coupling contacts moves. If tension moves, connect contact of coupling of the compressor directly to the plus plug of the accumulator. If coupling does not work, so it is faulty and is subject to replacement.

If tension does not move on contacts of the compressor, check the corresponding safety locks. If safety locks as it should be, remove and check the compressor relay (see rice. Contacts of the relay of the compressor of the air conditioner).

When the relay is removed, and ignition is included, on contacts of the 3 and 5 nest of the relay there has to be accumulator tension. Connect contacts by the 2 and 3 crossing point, and check whether coupling works. If it still does not work, so conducting in a compressor chain is punched.
