Portable Koldfront air conditioner shows P2 and stops cooling; fan may continue.

Safety first: Turn off and unplug the unit before draining.

Steps to clear P2:

• 1. Identify mode: Check if the unit was in heat or dehumidify mode; P2 often relates to condensate level in these modes.
• 2. Drain water: Locate the appropriate drain outlet (often higher on the back of the unit for heat mode) and attach a hose or place a container under it. Remove the cap and allow water to drain fully.
• 3. Check hose routing: Ensure any attached hose slopes downward continuously to the drain and is not submerged in standing water.
• 4. Inspect for clogs: If drainage is slow, gently blow through the hose or use a flexible brush to clear obstructions.
• 5. Reset and test: Replace the cap, plug the unit back in, and restart. P2 should disappear.
