Tappan Improper Combustion / Insufficient Air

Furnace ignites but the flame appears yellow and wavy instead of blue.

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 burners, blocked burner air openings, restricted combustion air to Tappan furnace, incorrect gas pressure

Safety: Yellow flames can indicate carbon monoxide production. Turn off the furnace and ventilate the area. Install or check CO detectors.

Steps:

Inspect the area around the furnace for obstructions blocking combustion air (boxes, insulation, etc.). Clear at least the minimum clearance specified on the furnace label.
Do not attempt to adjust gas pressure yourself.
Contact a qualified technician to clean burners, verify combustion air supply, and perform a combustion analysis.
