The part that usually fails on an ageing gas fireplace — and it gives warning if anyone measures it.
Generates the small voltage that holds the gas valve open, using heat from the pilot. Output declines gradually with age, so a millivolt reading at the annual visit predicts the failure months before it strands you. That measurement is most of the practical value of servicing a gas appliance.
