Hi, I have a INTERTHERM ULTRAFLEX central electric furnace and it is blowing one of the big fuses and I have very little heat output. Heating output is 41,000 btuh - model # FEH-012HA in a 83 KNOX mobile home. What could be the problem? Can I find a new heater like this one at a good price if I cant fix this one? Any around Rocky Mount, NC. HEY THANKS! drano4u2@aol.com
