Introduction
If your air conditioner is not changing temperature or you can not turn it on, there is a great chance that the problem lies in the circuit board. Over time, the circuit board can be damaged due to different reasons. Without the circuit board, the unit is almost unusable.
Use this guide to replace the circuit board in your Samsung ASV09PSBAN air conditioner or similar air conditioner if applicable
Before starting this guide, make sure to turn the power off in the room where the unit is connected. Turn off the circuit breaker that provides power for the unit. Without turning the power off, you may accidentally harm yourself or the unit.
