Error code 14 is displaying. When I turn off power and turn it back on the furnace ignites, all burners light and furnace heats until thermostate desired temperature is reached. I cleaned the flame senser with steel wool. The furnace works okay for a time or two again then repeats the error code...

My carrier furnace model 58MVP broke down this morning. Fault code is "4-2" - inducer rpm out of normal range. Any suggestions on how to obtain a new module and how involved the repair is? Have scheduled a service appointment, but no one can get her for at least next day at best. Thank you
