Dehumidifier powers on but compressor never starts, only fan runs

Safety: Unplug the Camry dehumidifier and wait a few minutes before accessing the compressor area.

Steps:

• 1. Listen for clicks: When the unit calls for dehumidification, listen for repeated clicking from the compressor area, which suggests start device issues.
• 2. Access compressor: Remove the rear panel to expose the compressor. Take off the terminal cover.
• 3. Inspect start components: Check the compressor start relay/PTC and overload for burn marks or melted plastic. Replace if damaged.
• 4. Test continuity: With a multimeter, verify continuity through the overload and relay according to their specifications.
• 5. Wiring check: Ensure all wires are firmly attached to the compressor terminals and not overheated.
• 6. Evaluate compressor: If new start components do not help, the compressor windings may be failing, requiring professional replacement.

Note: Compressor replacement is usually not economical on small dehumidifiers; consider unit replacement if out of warranty.
