Gas control valve issue???
Can anyone help. My peerless gas furnace started out with a failed transformer. After replacing the L8148E aquastat, the relay for the pump chatters alot. I shut it down and have chacked all components in the loop. I have a pilot and I have 24 V to the gas valve and the system runs OK with the gas control disconnected for the aquastat but as soon as I hook up the gas control vale, the relay chaters and the transformer is in overload. How do I tell if the gas control valve is bad (model V8200A)
PS, no resistance across gas control terminals.

When you say "no resistance", do you mean that the meter reads ZERO OHMS ? as in SHORT CIRCUIT?
In other words, if it's a digital meter, it reads 00.00 and not OL ?
or if analog meter, it swings all the way to the right ?
That valve should only draw around 300 milliamps, so that would put the resistance around 80 ohms or so if it was good.

Gas control
Thanks. The old control valve was a dead short, 0 ohms. The new one was ~500 and works great. This must be what cooked the transformer in the aquastat.
