Midea error code F0
What it means
Low refrigerant or low load protection.
Possible causes
System undercharge Slow leak on suction side Expansion valve malfunction resulting in low superheat
Suggested fix
Measure suction pressure and superheat, inspect for icing or frost indicating low load and check for leak sources; rectify leaks and reset charge using proper recovery and charging procedures.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
and electrical repairs must be carried out by a qualified, registered technician.
