Thanks GRJ; straight up gives a gap of 1/16 inch on my old board.
Thanks Hancock52; with the new board, I will also still have to install the fan motors into the reservoir, install the fan blades on the motors, and then solder the red and black leads to the board. Don't know if the board has holes in it for the leads. Don't know how the fan blades are fixed onto the motors. When they arrive, I will be consulting the forum on them. If all goes well with the new board, I may just order new resistors for the old board and install them - nothing like spare parts.
I will keep the forum up on my progress. Got a real charge out of using my meter for the first time and getting the ohms on the components. Also, taking the boiler off to get at the components is easy - be mindful of the wires for the lights at the front - they are short. However, there are boards that are buried - I would not attempt to replace the RCMC.
