RESTARTING A “STUCK” THREE-PHASE COMPRESSOR PROCEDURE
|25. Turn power off. Use the capacitor discharge tool (Figure SP-8-6) to discharge|
any capacitors in the unit. Locate and tag the wires connected to the
compressor motor terminals as shown in Figure SP-9-22, View A. (Refer to
the unit wiring diagram.)
|Leads connected to the compressor terminals are identified.|
|26. Disconnect the wiring connected to any two of the compressor terminals.|
Reconnect these two wires as shown in Figure SP-9-22, View B, so that two
legs of the three-phase input power are reversed.
|Wiring (leads) connected to any two compressor terminals are reversed.|
|Turn on the unit power.||Compressor starts as a result of the phase reversal. Proceed to step 28.|
|28. Turn power off. Use the capacitor discharge tool (Figure SP-8-6) to discharge|
any capacitors in the unit. Reconnect the two wires interchanged in step 26 to
their original connection points (refer to the unit wiring diagram).
|Compressor is wired according to the unit wiring diagram.|
