      If your Essick Air Conditioner fails to start, first, check that it's receiving electrical power. If power is available, inspect the fuse or circuit breaker; a blown fuse should be replaced, and a popped circuit breaker should be reset.

      If water is draining from the overflow in your Essick Air Conditioner, the float may be improperly adjusted; try adjusting the float. Alternatively, there might be lime buildup in the float valve, in which case you should clean or replace the float.

      If the motor in your Essick Air Conditioner cycles on and off, it could be due to several reasons. The motor pulley might be set too large, in which case you should adjust it. Excessive belt tension could also be the cause, so adjust the belt tension. Lastly, a frozen blower shaft can cause this issue; lubricate or replace the bearings.
