Question

Honeywell V810A1012 (NO OFF) - old Lennox G8D2-82-4


My furnace was working fine, winters over, time to turn off the pilot, and close the gas for the summer.

Did the usual, on the gas control I turned it from "ON" to "PILOT". Usually then turn it to "OFF", and close the gas supply.

Problem: It wont turn to "OFF", its like the 'plunger' isnt popping up high enough to turn off. I know forcing these things is not a good idea. So, I just left it in "PILOT" and closed off the gas supply.

The big picture: my house just went on the market two weeks ago, not looking at replacing the furnace, although I am sure the next guy will/should. I am sure the house will sell before next winter, but this isn't the kind of thing you leave hanging, and will show up on a home inspection (I would hope it would, as a soon to be buyer).

FYI: I have absolutely no intentions of fixing the gas control unit, or opening it up.

I see them on the internet for about $150, $90 used which is reasonable. Sample photo currently on the net:

Gas supply still off, I tried to push the 'plunger'/dial down and see if I could still move it to "PILOT". It worked.

Next, I tried to move it to "OFF". It worked.

So, my problem has gone away, but do I have a little problem waiting to poke its head up again, or to become a big problem?

Turn the gas on and relight the pilot and leave it alone. You pay a minimum charge of $10 or more/month for gas for the meter service etc whether you turn it on or off. It will burn about $1 for the Summer.

DO NOT buy a used gas valve as they are unsafe and a LOT of the time gas leaks around the stem of the handle you turn as the grease in there dries up over time.

The handle is stiff because the grease in there is old and dried up, not a problem unless you smell gas leaking out there.

I will trust your Winnipeg advice to light it an leave it.

Relighting is a pain if I wait till fall anyway, I think a lot of air needs to purge before the pilot stays lit.

Home inspectors are as dumb as dirt and not likely to say much about a furnace unless flames have been coming out.

It takes 60-120 seconds B4 the thermocouple in the flame/pilot burner warms up enough for it to stay lit. that is normal.
