- Old-BiscuitExplorer IIIWhat do you have to lose.......it ain't working now so if it gets messed up you would need a new board anyway

Sure.........
If you know how to solder and know/find the relay
I located the relay. Switch was open then when I jumped the blower out it made. Would I be better to replace the whole board or is it safe to say the relay is probably the issue? Soldering is no problem. - Old-BiscuitExplorer IIISure.........

DC+ from a fused source goes to circuit board 'PWR' connection
*also the source of the DC+ to thermostat
When thermostat closes that DC+ comes back and goes to circuit board multi-pin connector
*also goes to Sail Switch
When circuit board gets that DC+ from the thermostat it sends DC+ to Fan Motor from the 'BLO' connection on circuit board
Got DC+ to 'PWR' on Red Wire
Get DC+ on Blue Wire at the multi-pin connection
No DC+ on Red Wire from 'BLO' to Motor
*Could be Circuit Board
*Could also be Sail Switch stuck Closed...Circuit board will not allow fan operation if Sail Switch is Closed BEFORE Fan runs

I will chech the sail switch when I get home from work. If the circuit board is bad, can one replace the relay on it instead of the whole board since I figure that's what is bad? - Old-BiscuitExplorer IIIDC+ from a fused source goes to circuit board 'PWR' connection
