8. My Evaporative cooling unit creating a burning smell | Smoke coming out of vents
A burning smell coming from a cooling system can be just the smell of the new filter pads and should dissipate after a second cycle. However electrical, plastic or a strong rubber burning smell while cooler is ON is an obvious sign of serious electrical issue related to the fan motor, main control board or a capacitor.
If factory fitted safety features doesn't shut off the system and cooler continue to run it can become a danger. Turn off Evaporative cooling immediately and arrange professionals to locate the source and eliminate the problem.
