Got this grill as a home gift. Cover and bottom are solid. Loved the grill, but. Used grill for 1 1/2 summers(got grill june 2016) was on my 5th 1lb propane canister. Started grill and the temp. was going up. After a few mins. Temp. stop going up. Check the burner and it was out. Tried to start again but it would not light. Turned regulator off. Using a new canister turned 3/4 and heard gas from the burner. Tried many times to install canister. Same thing every time. Must must be the regulator.
