i have a amtrol 41 it has been working fine, however recently it seems to have been leaking (dripping) for some time. i realized that the wire( i think that what it is) that goes from the board (maybe the heat temp probe) to the middle of underneath the heater is dripping from the where the wire goes in to the tank. is there a fix for this problem or should this heater be replaced? will silicone take care of this for the interm?
