What can cause the supply voltage to an electric heating system to drop below the minimum voltage when the unit is operated?

B) A dirty air filter may be causing a high evaporator fan motor amp draw.
C) Power wire is too small or there are poor connections at either end of the power wire.
D) This is normal. The minimum voltage only refers to the voltage with the unit off.
