NTI Ti-150

AFred

Having trouble with a trinity Ti-150.

When I got there it would ignite and run for 3-12 seconds and dropout.

Ez, bad flame recification. I knew it needed to be cleaned so I tear it down and it was nasty. CLR it, scrub it, CLR it, scrub it..... I get it all back together and grab my anylizer. I fire it up, same problem flame drops out after 3-12 seconds. Check flame current at ignition module 3~4. Pull it, clean it. No change. So I order a new flame sensor. Get back few days later slap in the new flame sensor. And tada, same problem. Check flame signal at module and I'm getting a solid 7. Now I'm getting an error code an 'ER6' (flame lock-out). I am not getting the 3 flashes on the fenwal (module). I'm stuck, what do I test next? I ordered a new module, of corse they dont stock them here in the metro, I mean why would a wholesaler keep repair parts in stock on such an old boiler?(7years) Sorry, I'm getting whiney too.



Ideas anyone? Am I missing anything obvious?
