Controls & Electrical

The Controls & Electrical category covers the components that power, protect, and control HVAC systems. From control boards and relays to contactors, capacitors, transformers, and switches, these parts are essential for reliable system operation and accurate diagnostics.

Whether you’re troubleshooting no-start conditions, intermittent operation, or communication faults, this section helps you quickly locate the electrical and control components that match your service workflow.

• Control boards & modules for system logic and sequencing
• Contactors & relays for switching motors and compressors
• Capacitors & transformers for proper voltage and motor performance
• Pressure, limit & safety switches for equipment protection
• Electrical accessories including wiring, terminals, and fuses

Always verify equipment model, voltage, amperage ratings, and wiring configuration before ordering. Electrical and control components are system-critical—follow manufacturer guidelines and safety practices during installation and testing.

Pro tip: Controls, boards, capacitors, and contactors are high-demand service parts with strong margins—optimize listings with clear specs and compatibility notes to reduce returns.
