Your control board's likely shot On a newer furnace like yours, the fan limit/thermostat function is performed by the control board and its onboard fan relay. This means that a continuously running blower is generally the fault of the fan relay getting welded shut, or occasionally something else failing inside the control board's logic. Either way, ...

With the water turned off to standing pilot gas water heaters, I suggest leaving the controller in pilot; that way it can not turn on the burner and damage the tank. This also keeps the pilot running and those pesky little spiders that love to build nests in the tubing away; then, when you return, just turn it to the proper temp: no hassle having to relight ...

I'm also not trying to blow up the apartment or gas myself, so I turned everything back to "off" until I know what's what. The good news is, it's hard to cause any trouble with these because they're designed to be safe. Also, small amounts of unburnt gas will quickly mix into the air and be no longer concentrated enough to burn. I used to have ...

Looks like: System "on" at B. 1 to pilot, 2 should either press or turn (and will need to be held, if it's what I think it is) and 3 should be pressed in (and will make a "clunk" sort of noise) one to three times. There should be some place you can see the pilot light - you might need to move a flap, you might not. When you see it light, ...
