Running light blinking	Call service for failed components

2. Compressor stopping and starting with short running time.

Possible Causes	Response
Incorrect temperature setting	Set 55°F to 60°F
Incorrect voltage	Check for voltage
Failed thermistor	Check thermistor by placing it in ice water and measuring resistance.
Failed components	Check compressor windings, start relay and overload protector.
Improper condenser airflow	Check for condenser fan
Dirty condenser	Clean condenser
Overcharge of refrigerant	Call service for removing refrigerant
Discharge or suction pressure too high	Call service for OEM information

3.Fan motor running but compressor is not

Possible Causes	Response
Incorrect power supply	Check for proper voltage
Incorrect or loose wiring	Check all wiring and connections
Failed components	Check start relay, start capacitor, overload protector and compressor.
Liquid refrigerant in the compressor	Call service for OEM information

4. Compressor running but fan is off

Possible Causes	Response
Fan blade bond	Check for proper clearance

Failed motors	Call service to check for open or shorted windings.

5. No cooling but compressor and fan are running

Possible Causes	Response
Evaporator airflow restriction	Check for airflow through evaporator
Refrigerant leakage	Check for loss of refrigerant
Refrigeration system restriction	Call service to check for restrictions

6. Temperature too high or unit running too long

Possible Causes	Response
Improper evaporator or condenser airflow	Check for air restrictions
Dirty condenser	Clean condenser
Iced evaporator	Defrost and reset temperature
Malfunctioning fans	Check both fans
Improper seals	Check door gasket and opening
Improper area to be cooled	Check for excessive load or incorrect installation
Low voltage	Check power supply
Operating 60Hz unit at 50Hz (or vice versa)	Use proper unit (60Hz for the Americas, 50Hz for the rest of the world)
Sealed system problem	Call service to check for loss of refrigerant or restrictions
Undercharge or overcharge	Call service to add or remove refrigerant

7. House circuit tripping

Possible Causes	Response
Incorrect fuse or breaker	Check for proper fuse or breaker
Incorrect or loose wiring	Check all wiring and connections
Failed components	Call service

8. Noisy operation

Possible Causes	Response
Mounting area not firm	Add support to improve installation
Loose parts	Check fan blades, bearings, cabinet washers, tubing contact and loose screws
Compressor overloaded due to high ambient temperatures or airflow restriction	Check for airflow blockage
Malfunctioning components	Call service to check for internal loose components, inadequate lubrication or incorrect wiring
