or failing to start despite receiving high-voltage input at the 5-pin connector

the VAL3518 (also identified as VAL03518) ensures precise fluid control and reliable system isolation during routine maintenance or critical compressor repairs

Copeland 998-0540-00 Limit Switch R-134A Reduced Hysteresis: Flexible material propertiesThe Copeland 998 0540 00 220F Limit Switch is a critical thermal protection component designed for commercial refrigeration and HVAC compressor safety. This discharge line thermostat monitors internal temperatures to prevent compressor overheating, effectively acting as a high limit cutoff. Engineered with a 220F trip point, the switch triggers when the discharge gas temperature reaches the safety threshold, interrupting the control circuit to protect
