The condenser coils are usually located under the refrigerator. They dissipate heat from the refrigerator as refrigerant passes through them. If debris accumulates on the coils, the refrigerator will have to work harder to remove the heat. If the coils are significantly dirty, the refrigerator will run constantly in an effort to cool down. Your refrigerator’s condenser coils should be cleaned twice a year. 

If the refrigerator runs constantly, the defrost thermostat might be defective. Several times a day the defrost heater turns on for a few minutes to melt away any frost that may have accumulated on the freezer or refrigerator evaporator coils. In order for this to work, the defrost thermostat has to sense that the coils are cold enough. If the coils are cold enough the defrost heater will turn on. If the thermostat is defective it may not be able to sense the temperature of the coils and then w

The defrost heater assembly turns on several times throughout the day to melt away any frost that may have accumulated on the evaporator coils. If the defrost heater assembly is defective, the refrigerator will not defrost, and frost will continue to accumulate on the evaporator coils. If the evaporator coils are frosted over, the refrigerator will work harder to remove the heat. As a result, the refrigerator will run constantly in an effort to cool down. 

If the Refrigerator runs constantly the door gasket may be torn or defective, or if the door is not shutting tightly warm air can enter the the refrigerator and cause the evaporator coils to ice over. This happens because humid air from the room is drawn into the refrigerator through the opening at the gasket. As the humidity comes in contact with the cold evaporator coils it condenses and freezes. Normally the defrost system removes this frost and ice. However, if the door gasket is defective 

If the refrigerator runs constantly, the evaporator fan motor might have failed. Every refrigerator has a set of coils called an evaporator. The refrigerator may have one or more evaporator fan motor(s) depending on the model and evaporator locations. The evaporator fan motor circulates the cold air from the coils thru the compartment. If there is only one evaporator it is in the freezer side. If the fan is not working, no cold air will get to the refrigerator compartment. 

 If the refrigerator runs constantly, the defrost control board might be defective. The defrost control board monitors several conditions and determines how often to run the defrost cycle. If the board fails, the refrigerator will not go into the defrost cycle. Eventually, ice will build up on the evaporator coil and then the refrigerator and or freezer will not stay cold enough. 

 If the refrigerator runs constantly, the defrost timer might be defective. Two or three times a day the defrost timer is supposed to turn on the defrost heater to melt away any frost that may have accumulated on the freezer evaporator coils. If the timer is defective it won't advance and won't turn on the heater. 

If the refrigerator runs constantly, the main control board might be defective. A few times a day the control board is supposed to turn off the cooling system and turn on the defrost heater to melt away any frost that may have accumulated on the freezer evaporator coils. If the control board is defective it could cause the system to never cycle into defrost. 

If the refrigerator runs constantly there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. The condenser fan motor draws air over the condenser coils to cool them. The condenser fan motor is located underneath the refrigerator near the back. Pull the refrigerator out from the wall and remove the access panel to access it. 

 The cold control is a temperature-controlled switch that supplies power to the compressor and fan circuits in the refrigerator. If the compressor and fans are operating normally but not running often enough or long enough to maintain the correct temperatures in the fresh food and freezer sections, then the cold control may be defective or out of calibration. Normal fresh food temperatures are in the 38° Fahrenheit range with the control set to mid-point.

 In models that use an Electronic Control, a thermistor or temperature sensor may be used to monitor fresh food and freezer temperatures. The sensor is a small capsule like device that is protected by a plastic shield and will vary in resistance depending on the temperature. The control board uses this information to turn on the compressor and fan circuits as well as to operate the damper control on some models. 

The defrost heater assembly turns on several times throughout the day to melt away any frost that may have accumulated on the evaporator coils.

To determine if the water supply tube is frozen, disconnect the tube at the bottom of the door and blow air through it. If air does not pass through, this indicates that the water supply tube is frozen. If the water supply tube is frozen, thaw it out. In addition, ensure that the freezer is kept at the proper temperature. The freezer temperature should be kept from 0-10 degrees Fahrenheit. If the freezer is too cold, the water line may freeze. 

 The water inlet valve opens to supply water to the dispenser. If the water inlet valve is defective, or if the water pressure is too low, the water valve will not open. The valve requires at least 20psi to function properly. Make sure that the water pressure to the valve is at least 20 psi. If the water pressure is sufficient, use a multimeter to test the water inlet valve for continuity. If the water inlet valve does not have continuity, replace it. 

 The dispenser control board governs most of the functions of the dispenser system. If the control board is faulty, it may stop supplying power to the entire dispenser system. If only one dispenser part is not working, test each of the dispenser components before testing the control board. It is more likely that a single part has failed. If the entire dispenser system is not working, the control board is more likely to be at fault. 

 The dispenser switches send voltage to the dispenser. If one of the dispenser switches is defective, the dispenser will not work. To determine if a dispenser switch is defective, use a multimeter to test each switch for continuity.

 The door switch turns off the ice and water dispenser when the refrigerator door is open. If the door switch fails, the dispenser will not turn on. To determine if the door switch is defective, use a multimeter to test it for continuity. 

 A clogged water filter can restrict the flow of water to the dispenser and prevent the dispenser from working properly. The water filter should be replaced about every six months to maintain proper water flow and ensure water quality. 

 If the defrost drain is frozen, the water will overflow the drain trough and drip down to the bottom of the compartment. This water can eventually leak onto the floor. Check the defrost drain to determine if it is clogged or frozen. If the defrost drain is frozen, thaw the ice.

The water filter head might be cracked, or the seal may be torn or missing. Inspect the water filter housing for cracks.

The water inlet valve opens to supply water to the dispenser and icemaker. If the water inlet valve is cracked or has a loose fitting, water will leak from the valve. 

Inspect the water tank assembly for any leaks. Be aware that the leak may be very small and hard to find. If you discover a leak, replace the water tank. Do not attempt to repair the water tank—glue will not stick properly to the plastic of the tank. 

Self-defrosting refrigerators are equipped with a drain pan. The drain pan collects the water that melts from the evaporator coils. In order to evaporate the water in the drain pan, the condenser fan blows warm air from the condenser coils across the top of the drain pan. Because the condenser fan evaporates the water from the drain pan, the drain pan does not have to be emptied. However, if the drain pan is cracked, it will leak water as the defrost cycle is running. 

 The water filter might be not fitted properly on the filter housing. If the water filter is not fitted properly, water may leak from the filter.
