Title: Clothes dryer air flow test device and method

Abstract: A device and method for checking the adequacy of the rate of air flow in a rotating clothes dryer drum having air flow passing through perforations in the rear wall of the drum into the interior of the drum. The device comprises a rotatable fan and a counter assembly arranged to register the number of revolutions of the fan. There is provided a structure for removably attaching the device to the rear wall of the drum over at least some of the perforations in the rear drum wall. With this device and method the rate of air flow to the clothes dryer drum may be tested by operating the clothes dryer and registering the number of revolutions made by the fan for a period of time and comparing that number to a number determined previously to be an adequate air flow rate.
