Hello,

My fresh air blower does not turn on sometimes, especially when it is very hot outside. I can open up the shroud and give it a little help with a screwdriver and it always starts. I have read this is most likely due to poor connection on the internal motor components due to wear. I plan to replace it, but understand there is also a starter. Should I replace that as well while I have everything opened up or is it unlikely to need replacement? Thanks.

The blower motor always used to be a permanent magnet DC motor that uses brushes and a commutator, with this type of motor low starting torque is most often down to worn brushes.

So the starter likely does not need replacing? Does the motor lend itself to replacing the brushes or should I just replace the entire unit?

I can't recall anyone replacing the brushes, once you've got the motor out it's easier/simpler just to replace the whole motor.
