the fuse is like a car fuse...blade type. On this board I believe it is yellow
If you want to post a picture of your board I can direct
thank you, ***** ***** to be an older version...can you please pan out with pic where I can see all components?
ok the big cube that sits in front of board..(transformer) that is what gets fried if the fuse is not there....we want to see if there is an inline fuse in one of the wires from that cube....or we need a meter to see if that cube is putting out 24v (which powers thermostat)
I checked the board number and you have no fuse. If the thermostat is dead then the the unit either has no power or the transformer is dead
you are very welcome and thank you for the pics.
I wish you the best
