0755 Fan Cover Missing - Heating - Furnace Cabinets -

Image Text: Operating a furnace without the fan cover can be dangerous as negative pressure can be created in the furnace room - sucking combustion products into the fan compartment and blowing them throughout the house > cold air return > the air filter will also be bypassed (causing the furnace components to get dirty very quickly) > air filter > supply plenum > vent connector > draft hood > combustion products > on many newer furnaces, an interlock switch senses when the cover is missing and will not allow the furnace to operate
