Westinghouse Improper combustion / incomplete burning

Furnace ignites but produces yellow, lazy flames instead of sharp blue flames.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Dirty burner orifices, Incorrect gas pressure, Insufficient combustion air, Wrong orifice size for fuel type (natural gas vs LP)

Safety: Yellow flames can indicate carbon monoxide risk. Install or check CO detectors and consider the furnace unsafe until corrected.

Steps:

Ensure combustion air openings to the furnace room are not blocked.
Have a qualified technician clean burners and orifices, verify gas type and orifice sizing, and adjust gas pressure according to Westinghouse specifications.
