Description: This one addresses a situation I have seem over the years. The burned spots on furnace control boards used on furnaces. Is this an indication of a component failure? This video is part of the heating and cooling series of training videos made to accompany my websites: graycoolingman.com and grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome. If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.
