Atwood propane furnace fan problem

Atwood Model 8520 propane furnace fan operating at a lower than normal speed. Is the fan a single or two speed fan ? If a two speed is it controlled by the circuit board mounted at the back of the furnace case , or a control on the fan ? Are there many problems reported of fan bushing or bearings causing a slow running fan ? We have two Atwood furnaces , one operates properly the other does not . The slow running fan still operates the sail switch but does not supply a lot of air to warm the back of the coach.

I believe it is only a single speed fan. Variation in speed might be due to friction or a bearing binding.
