  • Page 31: Basic Test Procedure

    8 Basic test procedure  8.1 Defective compressor  Compressors are single phase, depending on the model unit. All compressor motors are permanent split capacitor type using only a running capacitor across the start and run terminal. All compressors are internally spring mounted and externally mounted on rubber isolators. 8.1.1 Compressor wiring test Remove compressor terminal box cover and disconnect wires from terminals.
  • Page 32 The reason for compressor inefficiency is normally due to broken or damaged suction and/or discharge valves, reducing the ability of the compressor to pump refrigerant gas. This condition can be checked as follows: 1. Install a piercing valve on the suction and discharge or liquid process tube. 2.

    connected in series with the common motor terminal. Should the internal temperature and/or current draw become excessive; the contacts in the overload will open, turning off the compressor? The overload will automatically reset, but may require several hours before the heat is dissipated. 8.1.7 Checking the internal overload 1.
  • Page 34 8.2.3 Hermetic compressor replacement. The following procedure applies when replacing components in the sealed refrigeration circuit or repairing refrigerant leaks. (Include Compressor, condenser, evaporator, capillary tube, refrigerant leaks, etc.) 1. Recover the refrigerant from the system at the process tube located on the high side of the system by installing a line tap on the process tube.
  • Page 35: Fan Motor

    1. Recover all refrigerant and oil from the system. 2. Remove compressor, capillary tube and filter drier from the system. 3. Flush evaporator condenser and all connecting tubing with dry nitrogen or equivalent, to remove all contamination from system. Inspect suction and discharge line for carbon deposits. Remove and clean if necessary.
  • Page 36: Capacitor

    1. Determine that capacitor is serviceable. 2. Disconnect fan motor wires from fan speed switch or system switch. 3. Apply "live" test cord probes on black wire and common terminal of capacitor. Motor should run at high speed. 4. Apply "live" test cord probes on red wire and common terminal of capacitor. Motor should run at low speed.

    and then gradually move back to infinity. 4. Reverse the leads of the probe and momentarily touch the capacitor terminals. The deflection of the pointer should be two times that of the first check if the capacitor is good. 5. Repeat steps 3 and 4 to check fan motor capacitor. NOTE: A shorted capacitor will indicate a low resistance and the pointer will move to the "0"...
