Did you read the manual? As mentioned--- have any power? Check the filter/bag for fullness? Is the plug-in on a GFCI (as required in a garage)? The intake at the unit should work even if other remote ones don't.
Be safe, Gary

They leave a residue that impedes air-flow, costing you money.
Clean the ducting in the last six months? 17,000 dryer fires annually!
