ROUBLESHOOTING
Each open-top burner should have a steady blue flame on each port of the burner. Propane burners may have a small
amount of yellow tipping, and may make a slight popping noise when turned off.
If the flame is rising up off of the ports, adjust the burner shutter so it is more closed. If the flame is long and yellow
adjust the burner shutter so it is more open.
Consult the following table and the flowchart on this page.
Problem
No burners or pilots in the range will turn on.
Spark electrode does not spark (to light pilot).
All burners produce excessive carbon deposits.
Only some burners in a range produce excessive carbon
deposits.
Only some pilots produce excessive carbon deposits.
Top burner will not come on, but oven will come on.
Open-top burner pilot will not stay ignited.

Troubleshooting Open-Top Burners
Remove each burner and check that the venturi is clean and free of buildup and debris. Also check that the
Remove the burner control knobs and carefully lower the control panel. CAUTION! Convection oven models
Check that each burner valve and orifice is in alignment with the corresponding burner.
Check the pressure of the gas supply with all the gas appliances connected to the supply turned fully on. The
inlet pressure (before entering the pressure regulator for the range) must be a minimum 7" W.C. for natural
gas, or a minimum 11" W.C. for propane but no more than 14" H
Check the pressure of the gas manifold of the range (after the gas leaves the pressure regulator for the
