How do you fix something that won't stay broken?

Mr. Nichols,

Thank you very much for this update! I haven't made any decisions or purchases yet, as i have until February to resolve this issue, and the furnace still works most of the time. The trailer doubles as my home office certain days of the week, and if the furnace doesn't feel like working, i have a small space heater to warm me.

If the RV repair shop happens to note any definitive failure points, please let us know.

Regards.
