Some of these Bradford-White's have 2 thermo-piles and operate a vent dampe
r motor that uses the voltage from one (or both) of the thermo-piles. There
is a micro-switch in the vent damper...if this is out of position...the bu
rner will not light. I've also had a bad connection (crimped spade) on a th
ermo-pile that was replaced. Causing a loss of pilot flame.

Interesting! Thanks! I don't think that I have that kind but I might.
Plumber did think of that but my garage is very clean. It's an odd little
garage. Not big enough for a car. Maybe a Smart Car. I mainly use it for
a pantry and other storage.
He did replace the pilot assembly and will be checking to see how the
venting should be. He said on these newer units, everything is much more
Plumber got it to light right away but he had difficulty moving the button.
I said that happens. It's either easy to move or it's sticky. There are no
other gas appliances. He does think the venting may be wrong for this kind
of water heater but may have been fine for the old one.
My house is nearly 120 years old and the basement is pretty dusty and
I've never had any such problem.
I've been informed that they still do make water heaters with pilot
lights, so I know the OP is not trolling.
I did just recall however that I had a gas appliance (can't recall if it
was a drier or a water heater) with a pilot light adjustment.
If it was set too low it would alway go out...I'd check that .
They checked a variety of things. This particular guy was new to this
company as of about a year ago. He fixed my sink prior. But I don't think
he is new to the business. He did have a trainee with him. He put in a new
pilot light assembly.
I had it set to the "hot" position. Well, prior to the plumber coming. I
just got so fed up and frustrated that I turned it off. Water should be
about 120 degrees at that setting. When he tested the water coming out of
the tank, it was 105 which was odd. It had been running cold and had only
been on for perhaps 10 minutes but he said that may have been enough,
coupled with our unseasonably warm weather.
What wasn't right though was that 20 minutes after lighting the pilot, the
water at that setting was 145. So that wasn't good. I did have two air
fresheners sitting on the top of it. The kind in the plastic jars with the
beads inside. One new, one opened. He said those could have caused a
problem. Likely not but they could have.
