Nordyne Their mobile home furnace is a lemmon O'Fallon, Montana
I purchassed a Nordyne furnace for my mobile home four years ago.
Model M1MB 070A AW
In those 4 years I have had to replace the Combustion blower assembly, (model 903404), 3 times, and the Pressure switch (MODEL 632453), 2 times.
This new furnace has failed 3 out of the 4 past winters!
