Overheat and high 

temperature protection

Is outdoor ambient temperature higher than 53?

20 minutes after the complete 

unit is powered off.

Is heat dissipation of the indoor unit 

and outdoor unit abnormal?

Normal protection, please operate 
it after the outdoor ambient temp-
erature is normalized.

Improve the heat 

dissipation environ-
ment of the unit

Does the outdoor fan work normally?

1. Check if the fan terminal OFAN 
is connected correctly
2. Resistance between any two 
terminals is measure by an ohm 
gauge and should be less than 1K 
Ohm.

Replace the  
control panel 

AP1

Replace the fan 

capacitor C1

Replace the 
outdoor fan
