TESTING, ADJUSTING, AND TROUBLESHOOTING
RANGETOP BURNERS AND IGNITION
Servicing Rangetop Burners and Ignition
Burner and ignition servicing must be performed by a qualified
technician. Improper adjustments may be dangerous, cause damage
or harmful by-products, and may void the appliance warranty.
Ignition Hazard
Do not touch burners when the igniters are active (sparking).
3.1 Before Testing
Before testing rangetop burners and ignition, do the following:
1. Reinstall any loose components that may have been removed
earlier, such as burner caps, griddle, and grates. Be certain that
burner caps seat properly into the burner bases, burner bases and
Venturi tubes are aligned correctly, and that the ignition wires are
properly positioned.
2. To test for gas leaks, make sure the electrical power is removed
and the manual gas shut-off valve is open, and then carefully
check range components and gas supply for leaks using a gas
leak detector or bubble test.
3. After gas checks are complete and before testing, connect the
range to the electrical power supply.

3.2 Rangetop Burner Characteristics
If one or more rangetop burner blows out, the respective igniter
electrode automatically re-ignites the flame.
The flame should burn through each burner port, completely around
the burner cap (see Figure 4).

Burner ports
It is normal to hear the following during burner operation:
·
A slight sound that is associated with gas combustion and ignition.
There should not be a loud noise.
·
A clicking noise every time the gas cycles, coming from the
solenoid valves of the two left or two right burners.
·
If using LP gas, a slight "pop" sound may be heard at the burner
ports a few seconds after the burner has been turned off.
