York 90 plus upflow furnace summer HVAC operation.
The draft inducer fan runs continually and will not shut off until i kill power to furnace. HVAC working normally and keeping house cool.
Five red flashes diagnostic.
Question does a draft inducer fan even have to run when the airconditioner is on?
