Refrigerator PTC Starter QP-02 4.7 Ohm Triangle Black Component for Compressor Motor Start Relay Replacement Part
Refrigerator PTC Starter QP-02 4.7 Ohm Triangle for Compressor Replacement

This PTC starter is a service component designed to replace a faulty start relay on refrigerator compressors. When the compressor motor needs an initial boost, the PTC element provides a timed current surge and then reduces resistance as it heats, allowing the motor to run normally. The QP-02 model is a common triangle-shaped unit with a 4.7 ohm rating suitable for many domestic fridges.
Features and Construction

The starter is built around a PTC ceramic disc housed in a compact plastic casing. Its design focuses on reliable electrical performance and straightforward mechanical fit.
Material and Build
The PTC element is the core active component, carefully rated at 3-4.7Ω to match compressor start requirements. The external housing is moulded in black plastic that provides insulation and protection.
Size and Practical Fit
The triangle shape corresponds to the standard mounting pattern found on many refrigerator compressors. The unit weighs only 3g, making it easy to handle during installation.
Uses and Placement

This component is intended for service and repair use, particularly when the original starter has failed or is suspected of causing a no-start condition.
Event or Professional Use
Repair technicians will find this starter a convenient drop-in replacement for common compressor models. It is suited for service calls where a quick, reliable fix is needed.
Everyday Home Use
Homeowners with basic electrical knowledge can replace a faulty starter themselves, restoring their refrigerator's cooling function without calling a repair service.
Benefits and Buying Value
Choosing a correctly rated PTC starter helps ensure the compressor starts reliably and prolongs the life of the appliance.
Reuse and Low Maintenance
The PTC starter is a passive component with no moving parts, meaning it rarely needs attention after installation. Replacement is only necessary if the starter fails.
Why Choose This Product
This QP-02 model offers a specific 4.7 ohm rating and triangle form factor that matches many common refrigerator compressors. Its lightweight, compact design makes storage and fitting simple.
