Why does my hot water heater's pilot light keep going out?
posted by csox to Home & Garden (10 answers total)
I just moved into a new house (yay!), but the hot water heater pilot light keeps going out. It's relatively easy to relight, but a fairly large nuisance to not have hot water when expected. The heater is gas, 50some gallons, wrapped in fiberglass insulation, in the unheated garage. It sits in a closet-like enclosure that's missing a door/4th wall. There's a large piece of wood that leans against the closet, acting as the door. The access panel area to the pilot light has a removable metal face that is always on (except when we take it off for relighting purposes). The closet is on the landing of the garage stairs (there's a small apartment over the garage), and directly next to a door that leads outside.
The first time it went out we'd been moving, so both the car-sized garage door and the human sized garage door had been left open all day, so I'm thinking a draft knocked it out.
This time, the heater went out overnight, when both doors were shut.
Ideas? I'm hesitant to attach the piece of wood to the front of the closet as it's large/bulky, and I'm small...if I'm the one who has to pry it off later, it would be relatively difficult.
Any help would be much appreciated!
