My blower motor has three wires: RED-heating speed tap terminal, BLACK-cooling speed tap terminal, and WHITE-neutral terminals. Does that man the white wire can be moved to the heating speed tap terminal? I believe somebody said the three wires were for different speeds. If I changed the location (change the taps) of the red wire at the harness connection at the blower motor, would that allow me to determine if the problem was with the blower motor itself?
Before I start looking for a blower motor, I want to make sure that is the problem. Any suggestions would be appreciated.
Does my Lennox G26 series unit have a fan limit control? Is it possible that is the problem?
