1) Connect the motor with the run capacitor directly in the
circuit. If the motor does not work it has to be replaced.
2) In case the motor works but the current drawn is too
high it is necessary to see if the motor is shorted
checking all connecting cables.
Compressor
Before carrying out the test all cables must be
disconnected from the compressor, and its motor must be
checked to be sure that its windings are not shorted and/or
interrupted. Then:
1) Put a lead of the test circuit in contact with the
compressor body in an unpainted area in order to check
the insulation.
2) Put one of the leads on terminal “C” and the other one
on terminal “S” of the compressor in order to check the
continuity of the start winding.
3) Secure one of the leads on the compressor terminal “C”
and the other one on terminal “R” of the compressor in
order to check the continuity of the run windings.
Check that winding resistances correspond to the figures
given in the table 2 and that there is no ground leakage.
