Code Text Description Cause Check Procedure Technical Support Notes 5110 Outdoor inverter heatsink thermistor error. Reduced airflow through inverter heatsink. Heatsink sensor faulty.
Open/short circuit sensor, disconnected from PCB. Check inverter heatsink is clean.
On the YGM-A series this can be either THHS1 or THHS5. To find out which it is you will need to check the inverter detail code using SW1 on the control board. Turn on SW1 dips 1,2,5,6,8 and look at the display for the code to be retrieved. THHS1=01 and THHS5=05.
