A modern gas furnace will not function with reverse polarity. I haven't seen anything else that cares, but I am sure there are some other appliances. Regardless, it is still a hazard and should be repaired. ... Traditional reversed polarity occurs when the black (ungrounded) and white (grounded) conductors are reversed.3.Reversed line voltage polarity: Reversed line voltage polarity is an electrical issue that can lead to the Carrier furnace yellow light code activation. It indicates that the electrical connections in your furnace have been improperly wired, causing a polarity reversal.Test wires, black is hot, white is neutral as they should. Hook up black wire to the HOT LINE side GFCI, and hook up white wire to the other. But it says hot and neutral are reversed on my tester. If I flip them around, which I can tell is wrong from the screw colors and directions, tester shows it's technically correct with open ground.38 Figure 3: Traditional polarity (cathode electrode) arc, 1kA, ~80V, 5cm length Figure 4: Reverse polarity (anode electrode) arc, 1kA, ~110V, 5cm length RESULTS AND DISCUSSION The three-dimensional reverse-polarity arc model was used to study a number of different cases. Of particular interest in such models is the degree of arcStep 1: Ensure Power is Turned Off - Before attempting to fix reverse polarity on a furnace, it is important that all power sources are turned off. This will prevent any potential shock or other hazards when working with electrical components. Step 2: Check the Ground Wire Connections - Next, inspect the ground wire connections for signs of ...
