LG Refrigerator Thermistor Assembly,PTC

The LG Refrigerator Compressor Starter PTC Thermistor Relay (Part Number: EBG62705806 / Model: QPS2-A33MC1) is an authentic original equipment manufacturer (OEM) replacement component designed for LG refrigerators. Mounted directly onto the compressor terminal pins, this Positive Temperature Coefficient (PTC) thermistor relay provides initial electrical current to the start winding, dropping its resistance to kickstart the motor and rapidly increasing resistance to cut off the auxiliary winding once the compressor reaches running speed.

Key Features

• OEM Precision Specifications: Factory-engineered by LG (Model QPS2-A33MC1) to deliver accurate resistance-temperature response curves for reliable motor starting.

• Solid-State Ceramic Disk: Internal high-reliability PTC ceramic element withstands frequent thermal cycling and electrical surges.

• Direct-Fit Plug-On Terminals: Outfitted with push-on female terminal sockets designed for direct attachment to compressor header pins.

Benefits

• Solves compressor non-starting issues, clicking sounds (overload tripping), or non-cooling conditions caused by a burned or cracked PTC starter disk.

• Protects the compressor motor windings from continuous high-current draw during startup.

• Direct OEM replacement ensures certified electrical safety and exact terminal spacing.

Applications

Designed specifically for select LG single-door and direct cool refrigerator models, such as GL-B181OBJB and GL-B181OFGB.

What's Included

• 1 x Genuine LG Refrigerator Compressor Starter PTC Thermistor Relay (EBG62705806 / QPS2-A33MC1)

Usage Instructions

1. Unplug the refrigerator from the main AC electrical outlet.

2. Access the compressor compartment at the bottom rear of the unit.

3. Remove the protective terminal cover housing over the compressor terminals.

4. Note the wire lead connections, then carefully pull the old relay off the compressor terminal pins.

5. Push the new LG EBG62705806 PTC relay firmly onto the compressor header pins, reconnect the wire harness leads, reattach the cover, and restore power.

Safety Instructions

• Disconnect main AC electrical power prior to opening cabinet covers or servicing internal components.

• Allow the compressor and old relay to cool before handling, as PTC components can retain heat after operation.

Care Instructions

• Keep the compressor terminal block area dry and free of excessive dust accumulation.
