| 3c. Motor windings shorted or motor shaft stuck, open selector switch, defective control. | 3c. Check for open or shorted motor windings, open selector switch, or control. | |
| 4. No cooling, compressor and fan motor running. | 4a. Airflow restriction. | 4a. Check for airflow through condenser and evaporator. |
| 4b. Sealed system problem. | 4b. Check sealed system for loss of refrigerant or restrictions. | |
| 5. Insufficient cooling, compressor and fan motor running. | 5a. Improper airflow. | 5a. Clean or replace air filter. Check for air passage restriction or obstruction. Check for dirty condenser, or evaporator. |
| 5b. Sealed system problem. | 5b. Check sealed system for loss of refrigerant or restrictions. | |
| 5c. Operating 60 Hz unit on 50 Hz current. | 5c. Advise customer that the unit should be operating on a 60 Hz electrical supply. | |
| 5d. Low voltage. | 5d. Check power supply (see 1b). | |
| 5e. Improper seals. | 5e. Insulating seals out of place or missing on unit. Doors or windows open. | |
| 5f. Improper use/size for area to be cooled. | 5f. Excessive load. Advise customer if load is excessive, or installation is incorrect, or inadequate. Instruct on proper operation of controls. | |
| 5g. Fan speed too slow. | 5g. Check for wrong motor, blower wheel, or fan blade. Check for binding of fan blade, blower wheel, or motor shaft. Check for low voltage and correct capacitor. | |
| 6. Compressor stops and starts. Too short running time. | 6a. Incorrect voltage. | 6a. Check for proper voltage. |
| 6b. Temperature control set too warm. | 6b. Instruct customer. | |
| 6c. Failed thermistor or thermostat. | 6c. Check thermistor by placing it in ice water and check resistance (see chart on page 4-1). | |
