Hi,

6A error is due to a problem with damper louver or limit switch, the most common cause is when ducting is secured to unit with long screws that infringe with louver movement.


To access the internals you can either:

Remove complete top section (there are screws under the foam)
Remove return air ducting /plenum from unit (extract duct)
Remove filter & heat exchanger then enter side of unit (only if you’re thin):confused:




Error detection method

Measurement of damper motor limit ON/OFF time.


Possible cause

Faulty damper motor or limit switch
Broken wire in cable
Faulty contact in connector (including relay connector)
Faulty control PCB assembly
:D:D:D
