Wiring size for AC Blower Board
« on: May 15, 2014, 10:29:33 AM »

I need to replace a number of wires and the blower control board in an AC unit.  See attached picture.  The larger blue/red/yellow wires in the forefront are 18 gauge and come from the blower itself.  I can't read any gauge on the other wires attached to the control board but I'm assuming its 20 gauge?  Confirmation would be great.  Thanks.  Model Comfortmaker BYMB024-030GA.  control board ICM255

Could strip the wire back and check it with a wire gauge.

A 20 AWG = 0.03196118 Wire Diameter in inches.
