Not related to motor specs however I had problems with mine and was able to lubricated to get it going again. By design the motor is expose to the elements, it's right under the grill with a louver over it. I removed the outside/top grill, would need to come off if replacing anyway, took a shop vac and cleaned the whole inside area, routed the lubricant via small hose to the top of the motor by reaching inside, long arms help, and sprayed. At first no-go but after it worked it's way through, it worked. Not sure how long it will last but it's an option before replacing
