CAUTION
Before measuring the compressor motor windings resistance, measure the
resistance of the multimeter probes by holding the probes against each other. If the
measured resistance is NOT 0 Ώ, this value MUST be substracted from the measured
winding resistance.
4 Measure the resistance between the compressor motor windings U-V, V-W
and U-W.
Result: All measurements MUST be approximately the same.
Compressor motor winding
measurements are correct?
Yes
No
5 Measure the continuity of the U, V and W wires between the compressor and
the PCB. If no continuity, correct as needed, see
6 Connect the Faston connectors to the compressor wire terminals U, V and W
