The grommets came apart metal from rubber.
I replaced the broken grommets with the new ones. I purchased 8 so I would have back ups because I did not feel the new one would last either. I think they cost TOO MUCH but I could not haggle for price.
saw burner tube was completely rusted at end and would not line up with burner. decided to go ahead and replace all three tubes. was easy to install, able to get a good cleaning job on unit in the process. works fine, wife is happy and that is what matters in a motorhome.
pull knob off streight out. remove two phillips head screws, disconnect wire to disassemble. To reassemble reattatch wire to replacement igniter, screw in two phillips head screws and push on the knob.
easy replaced after giving proper model and serial numbers. They were very helpful sending pictures so i could choose which knob might work as they had two for the same model number. The person answering my call was very helpful. Also return of the wrong ones I ordered was easy and refund prompt. I would highly recommend this company.Gail from Mo.
The old knob simply slides off the shaft. I aligned the fins on the back of the new knob with the grooves on the shaft of the ignitor and pressed the new knob on.
