Portable Insignia AC displays P2; unit may limit cooling or shut down intermittently.

Safety first: Unplug the unit before draining or opening panels.

Steps to address P2:

• 1. Drain both ports: Some Insignia portable models have upper and lower drain ports. Drain water from both to fully empty the system.
• 2. Inspect drain hose (if used): Ensure any attached drain hose slopes downward continuously with no kinks or loops that can trap water.
• 3. Clean internal tray: Remove the rear panel and locate the upper condensate tray. Clean out any buildup that could block the drain outlet.
• 4. Check upper float/sensor: Verify that the upper float moves freely and that its wiring is intact. Replace the float switch if it remains in the “full” position even when the tray is empty.
• 5. Test operation: Reassemble, restore power, and run the unit in COOL mode. If P2 reappears quickly, further inspection of the internal drain routing or sensor circuit on the main PCB may be required.
