Frigidaire 242278801 Refrigerator Thermistor Assembly

Product Description

The FRIGIDAIRE 242278801 is a refrigerator thermistor assembly designed to monitor air temperature inside the refrigerator compartment and relay that data to the main control board. The control board uses this signal to regulate cooling cycle frequency, preventing overcooling and reducing unnecessary compressor run time. Licensed appliance technicians and qualified service pros install this part when a refrigerator exhibits temperature inconsistencies, runs continuously, or fails to maintain a stable setpoint. It is a direct OEM-style replacement that restores accurate temperature sensing in the refrigerator section.

This thermistor assembly is suited for residential refrigerators where precise compartment temperature monitoring is required. When the sensor fails or drifts out of calibration range, the control board loses accurate feedback, which can result in food spoilage, frost buildup, or erratic compressor cycling. Replacing the thermistor assembly restores the closed-loop temperature control the system depends on for reliable operation.

Key Features

• Monitors refrigerator compartment air temperature and reports readings to the control board
• Regulates cooling cycle frequency based on detected temperature fluctuations
• Helps prevent overcooling and unnecessary compressor runtime, supporting energy efficiency
• OEM part number 242278801 ensures correct fit and function
• Direct replacement for restoring stable temperature control in the refrigerator section

Compatibility

Designed as an OEM-style replacement thermistor assembly for compatible FRIGIDAIRE residential refrigerators. Verify fit against your model number before installation.

Installation Notes

This part is typically installed by a licensed appliance repair technician. Before beginning any work, disconnect power to the refrigerator at the outlet or circuit breaker and allow the compartment to reach a safe working temperature. Handle the thermistor leads carefully to avoid damaging the connector or wire harness. After installation, restore power and confirm the control board is reading temperature correctly before returning the unit to service.
