Correct the Line Voltage Problem

Line voltage travels from the home breaker panel, to a service disconnect near the  furnace. … Furnaces (not hard wired) will have a plug in cord leading to a furnace panel door switch and then the transformer.  … Air handlers may have a service disconnect near the air handler, breakers as part of the air handler or fuses inside the air handler.  …  To correct the line voltage problem trace the voltage back from the transformer toward the house breaker checking for voltage on both sides of each component.
