7. TROUBLESHOOTING 7-1. Check before and after troubleshooting WARNING Hazardous voltage can cause ELECTRIC SHOCK or DEATH. Disconnect power or turn off circuit breaker before you start checking or servicing. 7-1-1. Check power supply. ● Check that voltage is in specified range (±10% of the rating). ● Check that power is being supplied. 7-1-2. Check lead wires and connectors. ● Check that coating of lead wires is not damaged. ● Check that lead wires and connectors are firmly connected.

7-2. Air conditioner does not operate. 7-2-1. Circuit breaker trips (or fuse blows). A. When the circuit breaker is set to ON, it is tripped soon. (Resetting is not possible.) ● There is a possibility of ground fault. ● Check insulation resistance. If resistance value is 2MΩ or less, insulation is defective (“NO”). Wall outlet (Receptacle) Power plug 1 Circuit breaker Window type air conditioner Power supply Ground WARNING * Set circuit breaker to OFF. 1 Pull the power plug out of the wall outlet.
PAGE 34
B. Circuit breaker trips in several minutes after turning the air conditioner on. ● There is a possibility of short circuit. • Check capacity of circuit breaker. Replace with suitable one (larger capacity). NO Capacity of circuit breaker is suitable. (Only for heat pump model) • Measure resistance of 4-way valve's winding. • Measure resistance of fan motor winding. • Measure resistance of compressor motor winding. 7-2-2.

(Only for heat pump model) • Check PCB Ass'y . (Power pack) 7-3-2. Electric heater does not work.
PAGE 36
7-3-3. Only compressor unit does not run. A. Check setting temperature. COOL mode HEAT mode (Only for heat pump model) Is room temperature too low ? Is room temperature too high ? NO NO Try to lower setting temperature by thermostat knob cooler. Try to raise setting temperature by thermostat knob warmer. B. Check compressor and electrical parts. Overload relay is working. (OLR) • Check compressor motor capacitor. YES • Measure resistance of compressor motor winding.
PAGE 37
7-4. Air conditioner operates, but abnormalities are observed. 7-4-1. Operation does not switch from HEAT to COOL (or COOL to HEAT). (Only for heat pump model) • Measure resistance of 4–way valve's winding. OK Check PCB Ass'y . (Power pack) 7-4-2. Poor cooling or heating. • Measure temperature of suction and discharge air of air conditioner. Temperature difference is small. Possibility of gas shortage. Charge refrigerant gas (R22).

8. CHECKING ELECTRICAL COMPONENTS 8-1. Measurement of Insulation Resistance Power plug ● The insulation is in good condition if the resistance exceeds 2MΩ. Ground Probe 8-1-1. Power Cord and Unit Insulation tester Clamp the grounding prong of the power plug with a lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the two power blade. (Fig. 1) Fig.
PAGE 40
8-2. Checking Motor Capacitor Remove the lead wires from the capacitor terminals, and then place probes on the capacitor terminals as shown in Fig. 4. Observe the deflection of the pointer, setting the resistance measuring range of the multimeter to the maximum value. Multimeter The capacitor is “good” if the pointer bounces to a great extent and then gradually returns to its original position. The range of deflection and deflection time differ according to the capacity of the capacitor. 8-3.
