Water Heater Keeps Turning Off? Do THIS.

A water heater that keeps shutting itself off is almost always doing it on purpose. A safety device inside the unit is cutting the gas or the power because something is wrong, and the real fix is finding what set it off, not forcing the switch back on over and over. This video splits the problem the way it actually divides, by whether your heater is gas or electric, because the two barely overlap. On a gas unit the burner lights and then dies, and we walk through why, starting with the free fixes like holding the control knob long enough on relight, vacuuming the clogged air intake screen at the base of the tank, and clearing a dirty pilot. From there we get into the thin metal sensor that sits in the flame, how to tighten, clean, test, and replace it for about fifteen dollars, plus drafts, a flammable vapor lockout, and the gas control valve. On the electric side we explain why that red reset button keeps popping or the breaker keeps tripping, from a stuck thermostat to a shorted heating element to sediment and loose wiring, and exactly when repeated tripping means you stop and call a pro. You can handle most of this yourself, and the parts and tools you might need are linked down in the description below. Sources: DIY Repair Clinic - Gas water heater pilot light troubleshooting.
