3.2 PIPING SYSTEM CONDENSER COIL FAN CAPILLARY TUBE MOTOR COMPRESSOR TURBO FAN EVAPORATOR COIL Figure 17 is a brief description of the important components and their function in what is called the refrigeration system. This will help you to understand the refrigeration cycle and the flow of the refrigerant in the cooling cycle.
3.3 TROUBLESHOOTING GUIDE In general, possible trouble is classified in two kinds. The one is called Starting Failure which is caused from an electrical defect, and the other is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application. Unit runs but poor cooling. Ineffective Cooling Check cold air circulation for smooth flow. Dirty indoor coil (Heat exchanger) Check outdoor coil (heat exchanger) & the fan operation. Check heat load increase. Clean condenser.
Fails to Start Check power source. Check circuit breaker and fuse. Check control switch setting. Gas leakage of feeler bulb of thermostat Check control switch. Compressor only fails to start. Fan only fails to start. Improper wiring. Drop of power voltage. Improper thermostat setting. Defect of fan motor capacitor. Defect of compressor capacitor. Loose terminal connection. Capacitor check. Irregular motor resistance ( ). Irregular motor insulation ( ). Improper wiring.
COMPLAINT Fan motor will not run. CAUSE REMEDY No power Check voltage at outlet. Correct if none. Power supply cord Check voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open. Rotary switch Check switch continuity. Refer to wiring diagram for terminal identification. Replace switch if defective. Wire disconnected or connection loose Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal.
COMPLAINT Compressor will not run, but fan motor runs. Compressor cycles on overload. Compressor cycles on overload. Compressor cycles on overload. Insufficient cooling or heating Excessive noise CAUSE REMEDY Thermostat Check the position of knob. If not at the coldest setting, advance the knob to this setting and restart unit. Check continuity of the thermostat. Replace thermostat if circuit is open. Capacitor (Discharge capacitor before servicing.) Check the capacitor.
