Safety first: Unplug the unit before removing covers. Compressor and capacitor work can be hazardous.

Step 1 – Confirm settings: Make sure the unit is not in standby mode and that any timer or delay functions are off.
Step 2 – Listen for compressor: After turning on, listen for a low humming sound from the compressor. If it never starts, suspect a start circuit issue.
Step 3 – Inspect wiring: Remove the rear cover and check all connectors to the compressor, fan, and control board. Reseat any loose plugs.
Step 4 – Check for overheating: If the compressor is very hot to the touch and not running, the start relay or overload may be faulty. These are often integrated on small RCA units and may require replacing the compressor start device or entire compressor assembly.
Step 5 – Professional diagnosis: If wiring is intact and the compressor will not start, contact a technician. Compressor and start device testing require proper tools and experience.
