Great video. I'm trying to run down a problem on a 5 year old Rheem RH2V6024STANJA unit where the air handler is sometimes kicking the fan on even when it's not calling for AC, sometimes fan turns off but comes back on after a few seconds, and sometimes it just stays running without calling for outside unit to come on. Some think it's the X13 motor and some think it's the control board itself inside the air handler. The control board is easy enough to replace but it looks like the board has changed from a part number 47-102077-03 to a smaller board number 47-100436-07. All connections appear to be the same so I would think it was just a running change to something different. In your experience, can this board cause erratic fan behavior if the thermostat and wiring has already been ruled out? Thanks!

A faulty board can cause odd issues to occur however, I would also check the motor and make sure the thermostat wiring is correct. Here is a great troubleshooting video for the X 13 motors:

@@kjfacilities-maint Thanks. I've talked to various HVAC people around town where I live and they tell me that those ECM's on top of the X13 motors seem to be problematic and the replacement Rheem brand name is way expensive and that there are other alternatives. This coming from actual local suppliers that I know. They say the ECM usually goes bad and the price to replace it is not far off from just replacing the whole motor. Sad that it's only 5 years old and was an expensive system, too.
