Common Problems and Solutions (Troubleshooting)

If you're experiencing problems with your Midea air conditioner, here are some points to consider:

• Weak Airflow or Ineffective Cooling:
  • Dirty Air Filter: Clean or replace the air filter. This is the most common.
  • Frozen Evaporator Coil: Turn off the unit and allow it to defrost. Make sure the filter is clean and free of blockages.
  • Dirty Evaporator Coil: Clean the coils to allow efficient heat exchange.
• Error Codes:
  
  • If the unit displays an error code (such as E1, E2, P1, etc.), refer to your owner's manual. Each code indicates a specific problem (temperature sensor, drain, overheating, etc.).
• Unit won't turn on or shuts off:
  • Tripped circuit breaker: Check and reset the circuit breaker in your electrical panel.
  • Compressor problems: There could be a short circuit or the compressor's temperature protection may be activated. In this case, technical assistance may be necessary.
• Low refrigerant level:
  • If there is a refrigerant leak, the air conditioner will not cool properly. This usually requires the intervention of a certified technician.
• Drainage:
  • Portable air conditioners accumulate water. If the unit isn't draining properly, it may display an error (such as P1) and stop working. Make sure to empty the water tank if it doesn't have a self-evaporating system, or that the drain hose isn't clogged.
