Airco 105-2 HBOE

[Gav D]

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

Blower not running?  High limit switch then kills combustion so furnace does not overheat.

Call a furnace repair company.

Limit switch, blower motor or the condenser on the blower motor - if it has one.

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.
