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.

Fan not working on outside AC unit


The buzzing noise is probably the fan motor. Is the compressor running? First make sure that there are no tripped breakers. After that kill the power and check the capacitor with a multimeter. If that checks good then check the fan motor windings with the multimeter. Let me know if you have any questions.

My air conditioner is on but not blowing cold air and buzzes


The compressor is not starting. The buzzing noise you hear is the compressor trying to start and then the thermal overload trips. When it cools it will try to start again. Could be a bad capacitor or the compressor is bad. These two units need to be tested to see which one is bad. A capacitor is inexpensive. If it's the compressor it will be cheaper to buy a new AC.

Squeeling noise coming from AC, compressor is on, fan not turning


The squealing noise is coming from the compressor. This noise is common when the unit reaches extreamly high pressures. The pressure is most likely high because the fan is not running. Since you can spin the motor it could be that the motor has damaged windings. Leave the unit off until the repairs are made to ensure no further damage to the compressor. You will need a multi meter and some experience reading wiring diagrams to properly diagnose the system. You can perform an amp draw on the motor to see if it is in spec. You can measure the volts to the motor and see if they are in spec. Finally the contactor can be measured with the proper meter to see if it is working properly.

My suggestion is to have the Motor and capacitor both replaced. Also inspect the wiring in the condenser electrical compartment for any signs of damage or burning.
