Sanyo wall mounted

[eurocooling]

Hi

i have a client who has a Sanyo wall mounted 9 years old and he says the flap does shut up when switch of is this something to do with the indoor pcb board

Could be a broken motor or flap linkages.

Does it move when operating?

Thanks it does move I will check when I go there

Also, thinking of the age of the unit there could be wear in the linkages or link connecters, think of square pins rounding off square holes.

Thanks for your advice
