How do I troubleshoot an E1 error code on my Midea AC?

Troubleshooting an E1 error can involve checking the power supply to the AC unit, inspecting the condenser coil for debris, and ensuring the refrigerant level is adequate. However, if you're not comfortable working with electrical components or refrigerants, it's best to call a qualified HVAC technician. Incorrect handling of refrigerant can be dangerous and illegal.
