Sinclair error code E2
What it means
System low-pressure fault.
Possible causes
Low refrigerant charge due to leakage Evaporator icing from poor airflow Restriction in the refrigerant circuit
Suggested fix
Inspect airflow across the indoor coil, gauge suction pressure and check for leaks or restrictions; repair leaks, clear blockages and recharge as needed before resetting the fault.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
and electrical repairs must be carried out by a qualified, registered technician.
