What to do if McQuay MAC 150 C Chiller compressor does not start?

  If the McQuay Chiller compressor doesn't start, several factors could be at play. First, check the power supply to ensure it's active. Also, inspect the fuses and circuit breakers; replace any blown fuses and reset breakers after fixing the underlying fault. A tripped safety mechanism could also halt the unit; identify the type of safety shutdown, correct the issue, and then restart. Loose wiring is another potential cause; check wire connections and tighten any loose terminal screws. If none of these resolves the issue, the compressor itself may be faulty, and you should contact your local dealer.

  If your McQuay Chiller isn't providing sufficient cooling, several factors could be responsible. Begin by checking the thermostat setting and reset it to a cooler temperature if it's set too high. Other potential causes, such as a dirty condenser coil, insufficient refrigerant, improper water flow rate, or contaminated water in the system, require contacting your local dealer. Also, make sure that there is no obstacle blocking air inlet or outlet of the unit, and remove it if there is any.

  If the compressor on your McQuay Chiller isn't starting, begin by checking the power supply to ensure it's properly connected.

Other potential issues include defective contactors or coils, which may need repair or replacement, tripped safety devices (determine the cause and correct it before restarting), or loose wiring (check and tighten all connections). If none of these steps resolve the issue, the compressor itself may be faulty, and you should contact a local dealer.
