Qps2C15md3 Refrigerator Compressor PTC Starter Overload Thermal Protector Relay A compact, purposebuilt PTC starter and overload thermal protector relay designed to help refrigerators start reliably and protect compressor motors from overheating and overload. The Qps2C15md3 combines the starting function of a PTC element with an integrated thermal overload protection/relay to reduce compressor wear, prevent damage, and minimize downtime. Key benefits Reliable starts: The PTC starter assists the compressor start winding to deliver a smoother, more consistent start under normal load and ambient conditions. Compressor protection: The builtin thermal overload protector interrupts current if the compressor overheats or draws excessive current, helping prevent motor burnout and costly repairs. Easy replacement: Sold as a directstyle replacement part for systems that use the Qps2C15md3 starter/relay, simplifying service and reducing downtime. Costeffective maintenance: Restores starting performance and protection without replacing the compressor, extending equipment life. Key attributes Model: Qps2C15md3 Functionality: PTC (positive temperature coefficient) starting element combined with an overload thermal protector and relay function for compressor motors. Compatibility: Intended for refrigerator compressors and refrigeration equipment that use or accept Qps2C15md3style PTC starter/overload relays. Check original equipment specifications and wiring before installation. Size and form factor: Compact unit designed to fit standard starter compartments and mounting locations used in refrigerator compressor assemblies. Construction: Built for reliable electrical contact and repeated cycling typical of compressor start/protect devices. Housings and terminals are made to withstand normal service conditions. Performance: Provides quick PTC start assistance and thermal response to temperature or current conditions to protect the compressor. Typical applications / use cases Household refrigerator : a failed or intermittent starter/relay in a domestic refrigerator to restore reliable compressor starts and overheat protection. Service and maintenance for refrigeration technicians: Carry as a common spare for onsite diagnostics and quick replacement when diagnosing start or overload faults. Small commercial refrigeration units: Use in compact refrigeration equipment where the Qps2C15md3 is specified or compatible to maintain reliable startup and lineside protection. Installation and compatibility notes Confirm that Qps2C15md3 matches the compressor's required starter/relay type and terminal configuration before installation. Disconnect power and follow safe electrical procedures. Installation should be performed by a qualified technician or person familiar with appliance service. Follow original wiring diagrams and mounting locations to ensure correct operation and protection. What this product solves Eliminates hardstarting or nonstarting compressors caused by a failed starter element. Protects compressors from overheating and sustained overloads that can shorten motor life. Offers a straightforward, serviceable option to avoid premature compressor replacement. Reliable starting and builtin thermal protection make the Qps2C15md3 a practical replacement part for compatible refrigerator compressors, helping restore proper operation and safeguard the motor during normal use.
