General Electric Refrigerator PSS23MSTCSS Frost buildup

The Defrost Thermostat is an OEM replacement part designed for use in GE refrigerators. This component acts as a safety device in the refrigerator's defrost system, preventing the freezer from overheating during the defrost cycle. It works by monitoring the temperature of the evaporator coil and turning off the defrost heater when the coil gets warm enough, thus safeguarding the freezer from getting too hot.  

Causes of a bad defrost thermostat can include corrosion, a blown fuse inside the thermostat, or wear and tear over time, which can lead to malfunctioning of the refrigerator's defrost system.

Symptoms of a bad Defrost Thermostat include:

• Frost buildup on the back wall of the freezer
• The refrigerator is not cooling properly
• The freezer is cold but the refrigerator is warm
• The defrost heater not turning on

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Defrost Heater Kit is an OEM part for GE refrigerators. It is designed to prevent frost and ice buildup within the freezer compartment by heating up at regular intervals to melt away any accumulated frost. For 12-inch glass tube heater use WR51X10055.

Symptoms of a bad Defrost Heater Kit include:

• Buildup of frost or ice on the freezer walls or around the evaporator coils.
• The refrigerator or freezer section becoming too warm due to blocked air vents by ice.
• Frequent cycling or longer running times of the refrigerator compressor.

Causes of a bad defrost heater can include failure of the heating element due to wear or a burnt-out component, malfunctioning sensors that regulate the defrost cycle, or electrical issues preventing the heater from activating.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Temperature Sensor is an OEM replacement part for GE refrigerators, designed to accurately monitor and relay the temperature inside the refrigerator and freezer compartments to the electronic control board. By detecting the slightest changes in internal temperature, the sensor allows the control board to make real-time adjustments to the cooling system, activating the compressor and fans as needed to maintain optimal conditions for food preservation.

Over time, the temperature sensor can fail due to electrical issues, exposure to moisture, or general wear and tear. A malfunctioning sensor can lead to improper temperature regulation, affecting the efficiency of the refrigerator and the freshness of stored food.

Symptoms of a bad Temperature Sensor include:

• The refrigerator or freezer not maintaining the set temperature 
• The appliance running continuously or more frequently than normal
• Inaccurate temperature readings displayed  

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 

The Ice Door Assembly is an OEM part for GE refrigerators. It is integral to the ice dispenser system, controlling access to the ice chute. This component ensures the efficient delivery of ice cubes or crushed ice when activated and seals off the chute when not in use to maintain the freezer's temperature and prevent frost buildup.

Symptoms of a bad Ice Door Assembly include:

• Frost or ice buildup around the dispenser area
• Ice escaping from the dispenser when not in use
• Failure to dispense ice
• Noise during operation indicating misalignment or malfunction

Causes of a bad Ice Door Assembly can include mechanical wear from frequent use, failure of the spring mechanism or solenoid that operates the door, or damage to the sealing surfaces that leads to air leaks.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Ice Dispenser Solenoid is an OEM replacement part for GE refrigerators. It is a crucial component that controls the flow of ice from the ice maker to the dispenser chute.

Symptoms of a bad ice dispenser solenoid include:

• Failure to dispense ice from the dispenser
• Ice getting stuck or jammed in the dispenser chute
• Continuous flow of ice even when the dispenser is not activated

Causes of a bad solenoid can include electrical malfunctions, physical obstructions preventing proper operation, or simply wear and tear over time.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.
