I have an Intertherm furnace that's in a mobile home. I've replaced the thermostat (which only has a red and white wire connected to it) and the flame sensor. I light the pilot light, and my furnace will come on for a few minutes, but then the flame dies. What else could be the cause of this?
Perhaps the fan/high limit? Dirty filter or blocked airflow? These are a couple of common suspects.
