Hello Sheri.
First I wanna say, that model is awesome, it works great and is silent...and should defenitly be repaired if possible.
I live in Qc, canada and have all u might need for repair...
maybe u dont even need any peice, only a good cleanup (filters and hoses)
I need more detail on sounds, troubles...also, Are you far way?
