What to do if the DIAL PEC-A-3500-1M Air Cleaner fan does not operate or runs slow?

If your DIAL Air Cleaner fan isn't operating or runs slowly, begin by checking the GFCI plug on the power cord to ensure it's properly plugged into the electrical outlet. If it still doesn't work, try resetting the GFCI outlet or using a non-GFCI outlet. Also, make sure the 'FAN' dial is set to 'L, M or H' to turn on the evaporative cooler. Check for a faulty motor capacitor, which may need replacing (for select models).
