Midea Mini Split Ac E1 Error Code – What It Means and How to Fix It

Got E1 Error on Your Midea AC? Here’s How to Fix It! Is your Midea AC flashing E1 error, leaving you wondering what went wrong? Don’t worry—I’ve got you covered! The Midea AC E1 error usually means a communication issue between the indoor and outdoor units, often caused by a mode conflict (one unit in cooling, the other in heating). If you have a multi-split system (mini split or Ceiling Cassette Air Conditioner) , make sure all indoor units are set to the same mode. How to Fix It: ✅ Reset the system – Turn off the Midea AC from the main power or circuit breaker, wait 10 minutes, then turn it back on. ✅ Check for loose or damaged wiring – If you’re comfortable, inspect the connections between indoor and outdoor units. ✅ Still not working? It could be a faulty control board or inverter module—time to call a technician.
