General Electric Refrigerator PFS22MISBBB Won't start or doesn't start

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. 

This PTC start relay and overload protector assembly mounts on the compressor. It manages compressor start-up and cuts power if overheating occurs. Replacing a failed start device may restore normal cooling and stop repeated clicking from the compressor area.

• Controls compressor start-up through a PTC start device that disengages after the motor is running
• Overload protector interrupts power if current draw or temperature is excessive to protect the compressor
• Visual clues of failure can include heat damage or a burnt odor around the start device

• Disconnect power and allow the compressor to cool before servicing
• Note wire positions; transfer wires and install the assembly on the compressor pins in the same orientation
• Ensure terminals are fully seated; do not force if fitment differs from the original
• If present, reconnect any external run capacitor exactly as originally routed

This condenser fan motor circulates air across the refrigerator condenser to help remove heat and support efficient cooling. Replacing a faulty motor restores proper condenser airflow and can prevent temperature rise and compressor overwork. What it does:

• Spins the condenser fan to draw air across condenser coils, aiding heat dissipation
• Helps the compressor run efficiently by preventing condenser overheating
• Common symptoms of failure: refrigerator or freezer running warm, motor not running, humming, or loud/abnormal fan noise
• Can cause longer run cycles and higher energy use when airflow is restricted or stopped

• Disconnect power to the appliance before starting any repair
• Handle the fan blade and condenser fins carefully to avoid damage
• Verify wiring and mounting locations match the original; secure all connectors and fasteners
