I have the same problem as described here but I don’t see what the fix is. The valve is fine when connected directly to the battery. The temp controls work - get 12V. But when connected in its place it does not activate the solenoid to close the valve?! Please advise or any insights welcome.

The only guess I have at this point is that one of the wires of the microswitch is on a strand - such that it provides a readable voltage but cannot carry the current to close the solenoid....

Solved the problem. Horray. 1kohm on the temp controller microswitch when activated!!!! Should be short circuit.
ie shows voltage but cannot support current.
