Aircon PCB repair and replacement in Singapore. Uncle 7 Aircon fixes control board faults, sensor errors and communication problems for inverter and non-inverter systems.

The PCB (printed circuit board) controls your aircon's brain. If the unit won't respond, shows strange error codes or keeps stopping, the control board may be at fault. We test and repair PCB issues accurately.
Minor PCB faults like loose connections or failed relays can be repaired. If the board is burnt or corrupted, replacement is safer and more reliable. We advise the most cost-effective option.
