Arrived at location on 8/11/21 - Customer explained kettle is trying to light but it will not light at all, pulled side over and inspected wiring and module all look good. Flipped kettle and pulled flame sensor attempted to clean. Tried to start unit up and could see unit spark, then fire, then go out. I believe unit is not sensing flame properly. Need to order flame sensor to repair unit. Returned to location on 8/13/21 - Installed new ignitor and flame sensor, tested and verified operations. No further issues.
