Partners Choice 632463 Core Ring Thermistor Ac

Product Description

The PARTNERS CHOICE 632463 is a core ring thermistor designed for residential split system air conditioners. This sensor mounts directly to the refrigerant coil and monitors coil temperature, sending resistance-based signals to the control board to regulate system operation and protect against freeze or overheat conditions. Licensed HVAC technicians typically handle replacement during a seasonal inspection or when diagnostic codes point to a failed or out-of-range thermistor reading.

This thermistor is intended for use in residential split system air conditioners. Confirmed compatible models include the PSA4BI-024K, PSA4BI-036K, and PSA4BI-048K. These units cover a range of residential cooling capacities and represent a common product family where this sensor serves as a direct OEM-style replacement component.

Key Features

• Ring-style mounting design seats directly onto refrigerant tubing or coil for accurate temperature sensing
• Provides resistance-based temperature signal to the main control board
• Supports freeze protection and thermal limiting functions within the system
• Designed as an OEM-style replacement for confirmed compatible model numbers

Compatibility

Confirmed compatible with the following residential split system air conditioner models: PSA4BI-024K, PSA4BI-036K, and PSA4BI-048K.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler and outdoor unit at the breaker before accessing internal components. The thermistor lead connections should be secured to the control board terminal as specified in the equipment service manual. Verify sensor resistance values with a multimeter against manufacturer specifications before completing reassembly.
