A propane regulator is a device installed on the fitting that connects the gas barbecue to the propane tank. The regulator prevents gas flow to the grill in the event of a gas leak. It is, however, possible to accidentally activate the propane regulator when no leak is present. Once the gas regulator activates, the temperature of the grill can only reach 121 to 149 degrees Celsius. When this happens, you can manually reset the propane regulator.
Open the cover lid on your gas barbecue and turn all dials to the "Off" position.
Turn the shutoff valve on the propane tank to the off position by turning rotating the valve in a counterclockwise rotation.
Disconnect the regulator from the propane tank by rotating the top of the regulator in a counterclockwise rotation.
Wait 30 seconds for the regulator to reset.
Attach the regulator to the propane tank by rotating the top of the regulator in a clockwise rotation.
Open the propane shutoff valve slowly by turning the valve in a clockwise rotation.
Use the barbecue's controls to ignite the gas barbecue. If you don't know how to ignite your barbecue, consult the owner's manual that came with your barbecue. Your regulator now is reset.
