MGmgsd Refrigerator Compressor PTC Starter QPS2-C4R7MD3 Overload Protector Relay Accessories 2

• 1.Principle: Starts with low resistance at room temperature. After powering on, it heats up, causing the resistance to spike and automatically disconnecting the start winding, with no mechanical contacts.
• 2.Usage: Suitable for small single-phase compressors like refrigerators and freezers, not ideal for frequent start-stop or heavy-duty equipment.
• 3.Selection: Resistance, voltage, and pin specifications must match the compressor’s original specs; do not mix or replace.
• 4.Issues: If damaged, the compressor may buzz without starting or trigger overheat protection; difficulty in restarting immediately after stopping is normal due to residual heat.
• 5.Operation: Keep it close to the compressor for cooling; wait 3-5 minutes before restarting after shutdown, and never short-circuit or use it while wet.
