Safety: Unplug the unit. Compressor circuits carry high voltage; if unsure, call a technician.

Steps to troubleshoot:

Check settings: Set humidity to the lowest setting (e.g., 30%) and ensure the unit is not in defrost or standby mode.
Listen for compressor: When the unit calls for cooling, listen for a click and a low hum. No sound may indicate a control or relay issue.
Access compressor compartment: Remove the rear or side panel to expose the compressor, start relay/PTC, and capacitor.
Inspect start components: Look for a cracked or burnt start relay and a bulging or leaking capacitor. Replace with GE-specified parts if damaged.
Test compressor (advanced): With power disconnected, remove the relay and test compressor winding resistance between terminals. If windings are open or shorted to ground, the compressor is bad.
Control board: If compressor and start components test good, the main control board may not be sending power and should be replaced.

Note: Compressor replacement requires a licensed technician and specialized tools.
