Normal Running Mode Condition
If the air conditioner unit has no faulty indications and the compressor is running at normal mode, the outdoor
P.C. Board’s LED indication will blink at a slower pace. The table below shows the significant meaning of
different running mode and limitation for this air conditioner unit.One must not attempt to see the LED
indication blinking unless instructed to do so.
Compressor Stopped Error Indication And Troubleshooting Guide
If the compressor stop unexpectedly, the outdoor P.C.Board’s LED indication will blink accordingly to the
error it detects. The table below shows the meaning according to the number of LED blinking and the
corrective action that one should take.
