Chiming in here as I just rec’d info about this and I just picked up my Kodiak 288BHSL on 8/17. I had emailed customer service inquiring about something else and they had sent this as part of their response.
“I did want to inform you of a service campaign that your unit has #18-318. It has been determined that certain Atwood furnace models may have wiring that can come in contact with the exhaust vent tube causing the furnace to shut down in a safe manner. This is not a safety concern and you may still use your unit, however we do advise you to have this looked at by your dealer.”
Prolly just go in there and look myself as she pretty much explained the issue.
