If you are searching the answer why your commercial LG oven has problems with lighting, read this abstract till the end. All top section burners are equipped with constant-burning pilots. These are to be manually lit immediately after the gas is turned on and the system is checked for leaks. Burner pilots are provided for each burner and can be rechecked for proper adjustment. Adjustments can be made with a screwdriver to the brass pilot valve accessible through the valve cover. Pilot gas is tapped from the thermostat, routed through tubing to a pilot safety valve, and then to the pilot
burner. Gas flow is controlled by the safety valve.
Oven pilot lighting or relighting is to be completed in the following sequence:
1 Turn the oven thermostat knob and oven manual shut-off valve to “OFF” and wait 5 minutes.
2 Remove the oven’s lower kick plate by lifting up and out.
3 Make sure any accumulated gas has dispersed. Since propane gas is heavier than air, check near the floor area for the odor of propane gas before attempting to light any pilot burners.
4 Depress the red button on the safety valve and hold it in throughout the lighting procedure.
5 Apply a lit match to the pilot burner head.
6 Continue to depress the safety valve button until the pilot remains lit when released.
7 If the pilot is extinguished, repeat steps 4 through 6 above.
8 Turn the oven manual shut-off valve and oven thermostat knob to “ON” and set to desired temperature setting, watch to make sure the oven burner ignites from the pilot and that there are no yellow flames from the burner.
If all is well, your pilot is now lit, however you still may need some attention, like cleaning the pilot and orifice. If not, you will need possibly a thermocouple for the pilot/safety, or a safety. Either of those call a local service company to check your appliance.
