TROUBLESHOOTING GUIDE 3.1 OUTSIDE DIMENSIONS 20-3/32" (499mm) 14-3/8" (366mm) 24" (610mm) 3.2 PIPING SYSTEM CONDENSER COILS FAN CAPILLARY TUBE MOTOR COMPRESSOR TURBO FAN EVAPORATOR COILS : REFRIGERANT FLOW Following is a brief description of the important components and their functions in the refrigeration system. Refer to Fig. 18 to follow the refrigeration cycle and the flow of the refrigerant in the cooling cycle.
www.sylvane.com 1-800-934-9194 3.3 TROUBLESHOOTING GUIDE In general, possible trouble is classified in two causes. 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/or improper application. Unit is running but cooling is ineffective Ineffective Cooling Check cold air circulation for smooth flow. Check outdoor coil (heat exchanger) & the fan operation.
www.sylvane.com 1-800-934-9194 Fails to Start Check power source. Check circuit breaker and fuse. Check control switch setting. Check control board Only compressor fails to start. Only fan fails to start. Improper wiring. Drop in power voltage. Improper thermostat setting Defect of fan motor capacitor. Defective compressor capacitor. Loose terminal connection. Check capacitor. Irregular motor resistance ( ). Irregular motor insulation ( ). Improper wiring Replacement.
www.sylvane.com 1-800-934-9194 COMPLAINT Fan motor will not run. CAUSE REMEDY No power Check voltage at outlet. Correct if none. Wire disconnected or connection loose Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal. Capacitor (Discharge capacitor before testing.) Test capacitor. Replace if not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged. Will not rotate Fan blade hitting shroud or blower wheel hitting scroll.
www.sylvane.com 1-800-934-9194 COMPLAINT Compressor will not run, but fan motor runs. CAUSE REMEDY Voltage Check voltage. See the limits on the preceding. page. If not within limits, call an electrician. Wiring Check the wire connections, if loose, repair or replace the terminal. If wires are off, refer to wiring diagram for identification, and replace. Check wire locations. If not per wiring diagram, correct. Capacitor (Discharge capacitor before servicing.) Check the capacitor.
www.sylvane.com 1-800-934-9194 COMPLAINT Compressor cycles on overload. Insufficient cooling or heating Excessive noise. REMEDY CAUSE Voltage Check the voltage. See the limits on the preceding page. If not within limits, call an electrician. Overload Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.) Fan motor If not running, determine the cause. Replace if required.
