Description

This thermistor assembly service kit replaces a failing temperature sensor to restore accurate temperature monitoring and control. Ideal for systems that need a direct-replacement sensing element and connector harness. What it does:

• Senses internal temperature and sends a signal to the control board for proper cooling/heating regulation.
• Commonly used when a unit reports incorrect temperature, runs too long, cycles frequently, or shows related error codes.
• Helps prevent overcooling or insufficient cooling caused by a faulty sensor.
• Replaces a damaged or intermittent thermistor connection that can cause inconsistent performance.

What's included:

• One thermistor assembly service kit (sensor with attached harness/connector as pictured)

Install notes:

• Disconnect power before starting work to avoid shock or equipment damage.
• Handle the sensor and wiring gently; avoid touching the sensing tip with bare hands or contaminating it.
• Route and secure the harness to match the original path; ensure connectors fully seat.
