998-1400-02 Copeland Thermistor & Bracket PTCR

The 998‑1400‑02 Copeland Thermistor & Bracket is an OEM PTCR start‑assist component used on Copeland compressors. This thermistor provides the correct resistance curve to help the compressor start smoothly without a traditional start capacitor. The included mounting bracket ensures proper placement and heat dissipation for long‑term reliability.

A failing PTCR can cause hard‑starting, intermittent compressor operation, or blown fuses. Replacing it with this OEM assembly restores proper starting performance and protects the compressor.

OEM Copeland thermistor + mounting bracket assembly used in PTCR‑based compressor start circuits. This component provides the correct resistance profile for Copeland scroll and reciprocating compressors that use a Positive Temperature Coefficient Resistor (PTCR) instead of a traditional start capacitor/relay kit.

This assembly ensures proper compressor starting torque, protects the motor windings, and maintains reliable operation in residential and light commercial HVAC systems.
