Description
Motor starter relay module, 1 terminal, marked QP2-15 or QP2-22 (select rating), for some refrigeration units.
The QP2 relay series is a positive temperature coefficient (PTC) compressor start relay used in various compact refrigerators, freezers, and wine coolers (such as Eurotech, Tuscany, Trieste, Haier, Midea, Homa, LG, Hisense, Danby, and Russell Hobbs).
Key Specifications & Features
- Resistance: 15 ohms and 22 ohms (Ω) at room temperature, depending on version
- Function: Gives the compressor motor an initial boost to start spinning, then increases in resistance to cut power to the start winding.
Common Signs of Failure
- The refrigerator fails to cool or the compressor refuses to run.
- A recurring "click-clack" or buzzing sound every few minutes as the overload protector trips.
- Rattling noise inside the relay casing caused by a shattered internal ceramic PTC disc.
