The boiler 3 way valve is not working. The maintenance person left a note that the 3 way valve is shot, and disconnected it at the board. We still have hot water. But it seems that the controller board has some cooked power resistor(s)
Has anyone any idea to ID the green power resistor that is visible on the lower part of the pict, I can read 470R, and 5%, and something else, but not too sure.
or is it the black cylinder? N06F
The other issue is that the board is really tight, and there is a poor access to the molex in the back to try to wiggle it loose. I need to make some prying plastic tongs
Thank you
