Clicking sound from compressor area; compressor tries to start but shuts off repeatedly and cooler does not cool.

Safety: Unplug the unit before touching compressor wiring.

• Check supply voltage: Use a multimeter to verify the outlet provides correct voltage (typically 115–120V). Low voltage can cause hard starting.
• Inspect and replace start relay: Remove the compressor start relay and overload. If burnt or rattling, replace with a Summit‑approved part.
• Allow cooling: If the compressor is very hot, let it cool for 30–60 minutes before retrying.
• Evaluate compressor: If a new relay does not resolve the issue, the compressor may be mechanically locked and require replacement by a sealed‑system technician.
