Rudd JGDG075AUER serCB5D302F38951719 After A/C hits its set point,Cond. shuts down blower keeps going. Remove 24v at board feeding stat,not that. Pull blower wire at "cool",nope! pulled blower wire at "heat" bingo! Got to thinking..,are hi limits etc. active in A/C call? in this unit they are. I had 24v.at all safty switches. They all tested Ok. BAD BOARD was my first and still diagnoses. Records show this is the 3rd board in as many years! I also checked voltage of unused blower wires while running in A/c mode.One to the heat spade was 115v,other 2 on park pins were 160v! ( is this normal,or do I have a blower that needs an exorcism?
