morning- got a vrv2 system, installed by our muppets 5 yr ago, 1 unit in canteen is noisy, start it up and after 30 mins the indoor fan buzzes its nuts off!
so i ordered a new motor,capacitor- fitted and again after 30 mins its noisy!- no outlets blocked, filters,coil clean.
swapped indoor pcb onto another unit-ran for 40 mins ok.
spoke with daikin technical and they suggested checking the power supply to the unit- checked and tested connections ok- as usual only time i can play with it is after 6pm for an hour and saturday mornings- no fault codes on the controller
