Removed four screws; withdrew two burners; set two new burners in place; installed same old screws. That was it. When I turned them on to adjust the flame, they came on almost instantly and no adjustment was needed.
Contacted customer service via email. Included a description of the problem as well as a photo that clearly showed that the Front Burner Assembly was, in fact, NOT an assembly when it arrived.
Nobody even acknowledged my email. This was a $140 assembly.
So very easy!!!! I'm a 70 year old grandmother with a small socket set - and that's all I needed! Removed one small screw, removed old burner, popped new burner in, replaced one screw, and back in business! Placed order, received it in 2 days, fixed burner. So much faster than calling a repairman!
