There is a smell coming from my cooler what should I do?

 

Drain, flush and clean the reservoir. Ensure the cooler has a bleed-off or Programmable Drain Pump installed. You may need to clean or replace pads. If you have new pads you should run your pump with out the blower for a period of time to wash out some of the smell, during which time you also dump the sump of the water that has washed the pads.
