Gav D 0 Posted November 11 Report Share Posted November 11 We have an Airco Furnace that has stopped blowing the warmed air through the ducts. The furnace ignites, runs for 3-5 minutes then shuts down. No warm air blowing from the ducts. Question 1: What might be the problem - advice for the technologically challenged please! Question 2: Do we need the furnace engineer or an electrician? Thank you kindly Quote Link to post Share on other sites
Jerry Simon 33 Posted November 12 Report Share Posted November 12 (edited) Blower not running? High limit switch then kills combustion so furnace does not overheat. Call a furnace repair company. Edited November 12 by Jerry Simon Quote Link to post Share on other sites
Marc 81 Posted November 12 Report Share Posted November 12 Limit switch, blower motor or the condenser on the blower motor - if it has one. Quote Link to post Share on other sites
Jim Katen 133 Posted November 12 Report Share Posted November 12 Call Columbia Fuels at 877 500-HEAT and get a tech out there to fix the problem, install a new nozzle, and adjust the burner while he's there. Quote Link to post Share on other sites
