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 supply unit
2. To compressor coupling
3. Tension of the accumulator
4. It is not used
5. Tension of the accumulator
6. Grounding

Press the button of the air conditioner and check as compressor coupling works. If coupling does not work, remove the switch of pressure of central air and close its contacts by a crossing point. If now coupling works, means, pressure in system too low or too high and system is necessary for examining 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 plusovy plug of the accumulator. If coupling does not work, means, it is faulty and is subject to replacement.

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

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