Frequently Asked Questions
Midea portable AC P1 immediately after draining — what to check?
Check the drain cap is fully seated. Also confirm the float switch inside the tank is not stuck in the raised position — rinse the drain area with water to free any stuck float.
Midea portable AC P1 appearing every few hours — normal?
In high humidity (above 70% RH) this is normal. The unit is collecting a large amount of water. Set up continuous drainage to eliminate the interruptions.
How is Midea portable AC P1 different from a dehumidifier FL error?
Both P1 and FL mean a full water collection tank — the difference is only the error code name used by the brand. The fix is identical: empty the tank and optionally set up continuous drainage.
