ENGLISH Maintenance and Service Common Problems and Solutions Troubleshooting Tips save time and money! Review the chart below first and you may not need to call for service. Normal Operation • You may hear a pinging noise caused by water being picked up and thrown by the slinger fan against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency. • You may hear the thermostat click when the compressor cycles on and off. • Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from the outdoor side of the unit. • The fan may run even when the compressor does not. Troubleshooting COMPLAINT Fan motor will not run. CAUSE I No power I Power supply cord I Rotary switch I Wire disconnected or connection loose I Capacitor (Discharge capacitor before testing) I Will not rotate REMEDY • Check voltage at outlet. Correct if none. • Check voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open. • Check switch continuity. Refer to wiring diagram for terminal identification. Replace switch if defective. • Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal. • Test capacitor. Replace if not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged. • Fan blade hitting shroud or cross flow fan hitting scroll. Realign assembly. • Units using slinger ring condenser fans must have 1/4 to 5/16 inch clearance to the base. If it is hitting the base, shim up the bottom of the fan motor with mounting screw(s). • Check fan motor bearings; if motor shaft will not rotate, replace the motor. I Revolves on overload Fan motor runs intermittently. • Check voltage. See limits on this page. If not within limits, call an electrician. • Test capacitor. Check bearings. Does the fan blade rotate freely? If not, replace fan motor. • Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor. Owner's Manual 23
