Hi guys hope everyone is well been called out to a VRV 2 of the indoor cassette are very noisey and vibrating heavily I has cleaned the out the units are spotless and I have made sure that the the supporting rods are fixed securely I am now think it could be the fan motor bearing is this a common fault on older units and if so is it worth repairing or just buying a new motor assembly

If it is the bearings then just get a new motor. Take the blade off and turn the shaft by hand is there any knocking or rubing?

Does it do it in fan only mode?

Check that the fan is not damaged.

I have had cases where the plastic has been damaged in the past and got worse with time. You can sometimes cut out a matching piece to re-balance the fan until such time as the replacement arrives.

Also check the fan motor mountings to see if they're loose. This can cause the unit to shake off balance too.
