Question about Mastercool 67680 Evaporative Cooler Air Conditioner

1 Answer

Noise My new Mastercool AC makes a terrible buzzing noise before it comes on like the motor is just sitting there buzzing then it finally starts blowing but I can't get the people we bought it from to send anyone to check it. I have to pay for someone to come check it myself. This is not right but what can I do?

If your warranty from the contractor is still in effect then I would demand that they come look at the problem. This however, does not guaranty that you will not have to pay. For instance if the new motor goes bad they might replace the motor for free but the labor may still be applicable. You will have to read through your contract with them to find out.

As far as the noise is concerned, It sounds like maybe a purge pump is failing. It could also be the motor failing due to (assuming the unit is new) a manufacturing default. The motor can also go bad if the belt is not adjusted correctly.

BUZZING NOISE


Is this noise a motor buzzing noise? If motor has power but the start circuit is not energized, then the power through the run winding cannot start the motor and may make a buzzing. Need to address the type of buzzing and if the motor, then check motor circuit.

Maytag dryer makes an electrical buzzing noise when start button


It sounds to me like the motor is not turning, but the heating element is coming on. with no air flowing over the element, it is getting too hot. Can you operate the start switch with the top tilted up so you can see if the motor is turning but the drum is not, and just where the buzzing is coming from. Also, I would try the dryer on manual setting and on air dry to see if any setting works. Good luck
