He folks,
I have a buck stove insert with a really really noisy fan. I've pulled the stove out to try and remedy the situation. What I found is that the shaft of the motor has a certain amount of play in the housing. not left right, but front/back. IE, If you hold the housing, you can push the end of the shaft forward or pull it back about 1/4 inch.
The shaft extends an inch or 2 out the front, and maybe 1 inch out the back of the housing, and there is a fan on the front, and what I guess is some type of balancing fan ( much smaller) attached to the back. The play front and back of the shaft in the housing is causing all the noise.
My question is, is that normal? should the "drive shaft" on an electic motor have some play in any direction? Is the the play in the shaft there by design?
The replacement motor I found is here
