Hi Guys,
The blower in my upstairs AC/Gas Furnace will not turn on. At first I went up there and tested the blower and it would not turn on even if I applied the 120V directly to it. So I replaced the blower and it will now turn on when I apply 120V directly to it. Unfortunately, the control board does not send the 120V to the blower as it should (AKA when the thermostat has fan set to "on".) What is interesting is that if I sit next to the unit and the wife turns the fan from auto to on I can hear a thunk--like a solenoid or something turns on. But still not luck. I checked and the G wire appears to close/open from the thermostat when going toggling auto/on.
I confirmed the transformer is putting out 26V and I see lights on the rest of the unit, so it is getting power.
Do I just replace the control board? It is this one:

If I need to replace the board should I go with one up there or the upgraded kind? (https://www.amazon.com/Upgraded-Honeywell-Replacement-Furnace-Control/dp/B00EFDUGG6)
The unit is 16 year old Heil.
Thanks,
