Just wanted to drop,a note regarding a friend’s laar’s heater (same as jandy lx400) that stopped working last week. It would come on and warm for a couple minutes then the AGS service error would pop up. After some research I pulled the fame prover sensor and gas orifices to clean them. Small amount of spyder webs in a few nozzles and not much buildup on the probe. Cleaned everything and put it back together and it's working great. Moral of the story is even a small amount of debris in the gas orifices can play havoc with the generating of a proper flame and cause issues (especially if its the burner directly under the flame probe).
