3 Things to Check When an Evaporative Air Conditioner Wont Turn on High

An evaporative air cooler is a popular alternative to air conditioning units for use in cooling off a home or a room, during the hot, humid summer months. One of the problems that homeowners will find with the evaporative air cooler is that they may have a problem with turning on high. If you have this particular problem, here are some things to check to fix the problem.

1. Check Control of Unit

If the air cooler unit is connected to a wall thermostat, the control box may not be engaging to let the fan turn from low to high. Check the master control box with a voltmeter to see if each of the components are working as they should.

2. Check Motor

If the control box is working as it should, then the motor of the evaporative air cooler may be the problem. Check to see if the motor is free and turns easily. Also, check to make sure that it engages the high speed fan. If not, you will need to replace it with a low-voltage motor to work with the control box.

3. Check Fan

There are times when the fan of the air cooler is not functioning properly. Check all the wire connections and whether or not the fan moves freely. The evaporative air cooler may be going into high, but the fan is not reading the message.

3 Top 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.

Reason 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 cooler to stop running. If this is the case, you need to first try to lubricate the bearings and then possible replace them.

Reason 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 noise and stopping issue from the motor.

Reason 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 to remedy your issue. Otherwise, you should purchase and install a new motor.
