On our 9410 we have a weird electrical issue with the cleaning fan actuator circuit. bear with me:

Dad called me saying the fan speed will only increase, I thought it was a bad decrease relay, changed the relay and still did it. I then switched the increase and first decrease relay, then it would only decrease(?????). then I got 2 of the lighting system relays (that worked) and put them in the fan circuit and it would still do the same thing(only either increase or decrease). do we have a bad circuit board or something?

Thanks in advance
