4.12.2. CONDENSER COMPONENTS REPLACEMENT
- Access the refrigeration group as escribed above.
- The condenser is in one block (A).
- Dismount it lifting and shifting the motor fan block (B).
- Separate the different parts (C).
4.13. MOTOR CHECKING
To check the motor electrical circuit integrity, continuity between phases has to be checked.
As there are three wires, such a measurement has to be carried out alternately, at the terminals of two of
them, choosing the third one as common.
The two resistance values obtained referred to two successive phases (as the state circuit is star-
configured). Check that :
1. The two values are identical (allowable difference ± 0.2 Ω).
2. The two values are not lower than 7 Ω (± 0.2 Ω).
3. There is no discontinuity.
If there is no conformity to condition 1, the motor can run erratically.
If there is no conformity to condition 2, the motor can run irregularly with over heating.
If there is no conformity to condition 3, the motor cannot run.
