manual off the web? It has a trouble shooting flow chart, it helps a
lot. we will assume that there is fuel through the filter, because
the unit run when you through the switch.We will also assume that
all the fuse are good. If the control mod tells the unit to start up
and the blower comes on, and the unit does not fire, the blower will
shut down and the light will go out. this could be caused by several
things. If the DC high temp stat has opened the fuel pump will not
get power, no fire. If the photo cell is covered with soot, then
when the flam is on, the light is not detected, and the fuel will
shut off, no flam, do you hear the burner fire and feel heat out the
exhaust? I would let it fail then do a continuity test on the DCV
high temp stat and see if it is open. Also the control mod could be
bad. I had a resetable high limit stat on my 95 BMC that went out. I
have replaced all the stats and the fuel pump,there was a recall on
some of the fuel pumps, they leaked, and replaced all the diesel
soaked insulation from the leak. The control stat that they sent me
was the wrong temp range, then the replacement was bad anyway I have
a intimate relationship with my Aqua Hot.
