Common Fixes

• Air conditioner compressor struggling to start
• Low voltage or brownout conditions
• Compressor humming but not engaging
• Frequent breaker trips during startup
• Hard starting in high‑temperature or high‑pressure conditions

️ Installation Instructions

• Disconnect power before servicing the unit
• Locate the existing run capacitor in the electrical compartment
• Connect the two wires from the PSA6 in parallel with the run capacitor (one wire to each side)
• Do NOT remove any existing wires from the run capacitor
• If all terminals are in use, attach using the included “piggy‑back” terminal
• Secure wiring and restore power to test compressor startup

This hard start kit provides a powerful boost for compressors under heavy load, restoring reliable startup performance in PSC air conditioning systems.
