Error Code COMP-LOW-VOLTAGE

Incoming power voltage is too low for the compressor to run safely

Critical

Stop using immediately - risk of damage or safety issue

Also displayed as: LED blinks per inverter protection table

What This Means

Supply voltage below AC 60V (110-127V systems) or AC 106V (220-240V systems); Short resistor R514 (DC link resistor) on PCB; Poor power connection or extension cord

What actually causes this:

The household power supply voltage dropped too low, which prevents the compressor from running to protect it from damage.

First Thing to Check

Plug a lamp or phone charger into the same outlet to confirm the outlet has normal power.

How to Fix

1
Check AC input voltage at the outlet and power cord
2
For 110-127V models: voltage must be above AC 60V
3
For 220-240V models: voltage must be above AC 106V
4
Check PCB bottom side soldering at R514
