All installations and services must be performed by qualified service personnel.
2.101.0 Check to see if the condenser fan motor is excessively hot as to cause the
1)Loose wire connections.
2)Excessive current (amp) draw, possibly due to low operating voltage.
3)Bad motor bearings.
4)Excessively dirty coil causing restricted airflow.
5)Excessively hot air being pulled into unit.
6)Stalled fan due to blockage of rotation
2.101.1 Make sure wire leads to the motor are making good connections. A loose connection can cause an excessive current draw and overheat the motor.
2.101.2 Check for defective fan run capacitor. Use an ohmmeter on highest resistance scale (i.e. R X 100,000 scale) or continuity. Full needle deflection or no audible sound indicates the capacitor is open. Replace the capacitor.
2.101.3 Check for continuity of the motor windings, as the motor itself may be damaged.
2.102.0 Make sure the discharged hot air is not recirculating back through the coil fins.
2.103.0 A slight restriction in the outdoor coil might cause an excessive head pressure that over time may cause the compressor to function on
2.104.0 Check for refrigerant overcharge by excessive liquid and suction line pressures.
2.105.0 If the suction pressure is low, add charge to see if the pressure comes up to the specified value on the
2.106.0 Check line voltage to the compressor to see if it is excessively high or low.
2.107.0 A defective run capacitor can also cause the compressor to overheat. Check out the run capacitor.
2.108.0 The compressor may be drawing excessive current due to an internal defect such as severely worn or damaged bearings.
2.109.0 Possible causes of a high superheat (15 deg. F. or higher) could be a faulty expansion valve or an extremely low charge.
3.101.0 A low suction pressure that could indicate the system is low on refrigerant charge. However, first review the following items.
