Compressor The compressor is located at the front of the refrigeration unit, beside the condenser. If the
compressor is causing excessive noise, check the mountings to ensure there is no damage to
the rubber or the washers, nuts and screws.
Before replacing the compressor, check all plug connections and ensure the compressor
electrics are operating correctly (see “Compressor Electrics” on page 41). The compressor
must be supplied with consistent voltage over 220 volts, ensure the voltage does not drop at
start-up. If the voltage does drop, ensure the unit has a direct power supply (not from a
multi-box or extension cord). Generally a faulty compressor may have a distinct hissing sound
and run with a very hot body temperature. Only replace the compressor if the capillary and gas
charge are first confirmed as absolutely correct (see “Servicing and Diagnosis Overview” on
page 32).
If replacing the compressor, move the evaporator tub and condenser fan assembly out of the
way to create space for brazing and to access the compressor bolts.
4. Attach to the replacement motor.
• Ensure that the flexible cord points towards the bottom of the evaporator tub once reinstalled.
• Take care to re-cable tie the fan and temperature probe flexible cords back onto the mounting
bracket to prevent high frequency vibration.
5. Fit fan blade, ensuring it is centred within the evaporator shroud. Tighten the screw to the fan motor
manufacturer’s recommended torque setting (see Table 11 above).
6. Reassemble unit and test for correct operation.
Procedure 35: To replace the fan motor (continued)
IMPORTANT
To eliminate possible vibration noise, ensure no pipes touch
the evaporator tub bottom surface, evaporator tub support
legs, plastic base, and condenser assembly (see image
above).
