Regulator freezing up
Just purchased from Home Depot on 8/30/08 and regulator freezes up not letting the propane supply get to the burners to heat up the grill. Went back to Home Depot to exchange regulator and still had problems. Going to take back to Home Depot because of bad reviews about Brinkman grills on the web from other consumers.

Answers & Comments
1. Are you using a portable LP cylinder? LP Regulators freeze up when the liquid part is the propane is flowing through the regulator this is caused by an overfilling of the propane tank.
2. If the BTU capacity of the regulator is not high enough to cover the BTUs of your grill, the regulator is working too hard and potentially pulling liquid (not vapor as it should)
I would suggest calculating the BTUs of your grill and looking to see what the capacity of the regulator you are using.
