    Trane intellipak flame failures

    I have a job with 10 trane intellipak units M#SFHFF50 and over the last 2 winters Iíve experienced several issues with random heat failures. Some Iíve found issues with bad actuators, ignition controls and wiring issues. But even after repairs are made and ones that have no issues Iíll get random flame failures. Iíve checked inlet and manifold gas pressures and everything is fine. Wanted to know if anyone has ran into this issue? Getting the service bulletins on theses unit from trane is a task. Iíve herd that people have switched the order of the PRV and solenoid on the pilot assembly or taken the burner apart and rotated the diffuser cone. Would like to get a definite fix for this issue. Any help would be great.

    What's your pilot pressure? Might try increasing it?

    Check combustion

    Check the head that the ignitor and flame rod screw into. Iíve seen them cracked which could cause nuisances

    Could also be high wind issues.

    Don’t forget changes in usage. I once had a casino with 7 of them. Every morning we would get the call that they weren’t keeping up. We would go down there to find zero issues. This went on and off for several weeks. One NIGHT we went down there...totally different story.

    Daytime. Warmer ambient. Mostly little old ladies spending their SS checks. No smoking.

    Nighttime. Colder ambient. Younger crowd. Smokers. So they opened up the OA Dampers farther requiring more gas. Found the regulator couldnt keep up at night but could during the day.

    perhaps you are riding the minimum gas pressure and then there is a dip in utility pressure. Maybe something else in the gas line is running. Stuff like that.

    Technically speaking, they are all heat pumps.
