General Electric Refrigerator PFSF2MIXBBB Ice maker not making ice

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 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 GE refrigerator water filter is an OEM replacement part responsible for ensuring the quality of the water dispensed on GE Profile top and bottom freezer refrigerators. It is responsible for purifying the water before it reaches your glass or ice maker, providing you with clean and safe drinking water directly from your refrigerator. To maintain optimal water quality and ensure the filter's effectiveness, it is recommended to replace the filter every 6 months or when the rated capacity of 750 gallons is reached.

Over time, the water filter can become clogged with sediment, reducing its effectiveness. Regular use and the accumulation of minerals and contaminants can lead to the need for replacement.

Symptoms of a bad water filter include:

• Reduced water flow from the dispenser
• Ice cubes with an unusual taste or odor
• The filter indicator light staying on
• Visible particles in the water or ice

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models. For the best performance, it is recommended to replace the water filter every six months or as indicated by the filter change light on your refrigerator.
