General Electric Refrigerator PSC23MSWCSS Won't start or doesn't start

The Compressor Start Device is an OEM replacement part for GE refrigerators. This start device is responsible for powering on and initiating the refrigeration compressor during each cooling cycle. 

Causes of a bad start device can include wear and tear over time, exposure to fluctuations in power or voltage that can damage electronic components, or accidental damage that impairs the device's ability to reliably power the compressor.

Symptoms of a bad start device include: 

• The refrigerator not cooling properly or only cooling intermittently
• The compressor not turning on at all or making unusual sounds when powered on  
• Warm air blowing from vents inside the refrigerator or freezer sections
• Frost or ice building up in areas it typically would not  

This OEM GE 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.
