Is it normal for a gas heater to switch itself off?
Sometimes a furnace keeps shutting off because the flame sensor is corroded or caked in soot.

Why does my gas fireplace keep turning itself off?
Since the switch is delaing with millivolts, even a small amount of resistance is enough to essentially “shut off” the fireplace, just as if you’d turned it off at the switch yourself.
