utica boiler

i have a aqua stat that when you wiggle the plug on the circuit board it will open the damper so i replaced the harness from the aqua stat and the same problem i have ordered a new aqua stat and talked to utica tech support they said there is most likely a cold solder joint on the board. sounds reasonable to me any suggestions not much left . the stat is a honeywell l8148e1257 according to utica . how does th stat work ? does it send 24 volts to the damper control and when it opens sends back voltage to the stat?
thanks safetyray ( i quess there is a lot of cold joints according to utica)
