Question about Mastercool 67680 Evaporative Cooler Air Conditioner
When I turn on the power switch for the air conditioner, the motor hums like it is trying to start but it won start turning the belt, until I help the bottom wheel move slightly ... then it runs like a champ.
Is my belt to tight? do I need to adjust something?
More than likely the pulley set screw is lose. Look on the inner hub of the pulley's both on the motor and the fan for a threaded hole with an allen head type of screw in it. Before you 'help' it to turn, look to see if one shaft of the other is spinning inside the pulley without the pulley itself turning. Buy a set of allen wrenches and tighten the screw. You may have to remove the belt to see the setscrew hole. It can be done by stretching it over the edge of the larger pulley and rotating it by hand. Put it back the same way. BTW make sure the power is OFF! fingers are still at a premium.
