Why is my grill not heating up more than 250 degrees?

weberAll regulators nowadays have included a safety device that restricts the flow of gas in the event of a gas leak. This safety device can be unintentionally activated in two ways, putting the grill into what is commonly called “bypass”. The first way for the device to be activated is to leave one or more burner control knobs in the “ON” position when the LP cylinder valve is opened. The second is not to wait long enough to “start” the grill after opening the LP cylinder valve. The safety device in the regulator is activated each time that the LP cylinder valve is opened. The device resets itself when the gas pressure equalizes between the closed burner control valve and the regulator, through the hose. If a burner control knob is turned on before the gas pressure can equalize, the device will remain in “bypass”. The length of time necessary to wait to “start” the grill after turning on the LP cylinder valve is dependent on the length of the hose and outside air temperature. It is always good practice to wait a few seconds after opening the LP cylinder valve before turning on the burner control knob to start the grill.

If the grill is in bypass, after checking for gas leaks, do the following to get the grill out of bypass:

Cart Based Models

  • Close the LP tank valve
  • Turn all burner control knobs to the OFF position
  • Now, start the grill by doing the following:
  • Open the grill lid
  • Turn the LP tank valve until it is completely open
  • Wait several seconds
  • Turn the front burner to the HI/Start position
  • Press the igniter until the burner is lit.
  • Turn remaining burners to High
  • Close the lid.
  • The grill should preheat to 500-550 degrees in 10-15 minutes
  • Turn all burner control knobs to the OFF position

Models with a side burner

  • If experiencing low temperatures on a grill with a side burner, such as the Genesis E/S 320, check to be sure that the side burner control knob was not left on. If the control knob was left on after the grill has been turned off, this can cause the grill to go into bypass.

 

Remember to change battery each year for proper starting too.
