I have a nine year old Carrier WeatherMaker gas furnace model 58MVP080 in which the blower motor quit. After reading past posts on this site I found out the pulse modulator was most likely the problem with my old motor but too late, I already have a new motor assembly. Reading other information and speaking with parts suppliers I get an indication that the motor has to be programmed. I am wondering if this is true and what actually has to be programmed. Does the motor need some programming prior to installation or does the furnace control board have to have some programming with the new motor? Any help would be appreciated.
