3 Causes for a Buzzing Swamp Cooler Motor that Stops Running
Many homeowners that utilize a swamp cooler in their home may experience a buzzing or humming sound from the cooler. The underlying cause of this noise could eventually lead your cooler to stop running. There are a few different things you can check that might be creating your swamp cooler noise.
1. Replace Bearings
If your cooler is making a buzzing sound and then stops running, one cause could be your bearings. If you do not properly maintain your cooler by keeping the bearings lubricated, they will dry, make noise, and eventually cause the swamp cooler to stop running. If this is the case, you need to first try to lubricate the bearings and then possibly replace them.
2. Motor Oil
The next place you can check is the motor oil. Make sure the oil appears clean and free from dirt and debris. If this is the case, you can attempt to change the oil and see if this corrects the issue.
3. Bad Motor
Finally, the cause could simply be that your motor needs to be replaced. The motor is one of the most expensive parts to replace in your cooler, so be certain one of the previous suggestions do not remedy your issue before buying a new motor.
