Abstract
An electronic control circuit (10) for a gas oven including a hot surface igniter (24) which is heated through the application of electrical current to a temperature sufficient to ignite gas supplied through an electrically actuable gas valve (26). The applied current is regulated by a micro-controller (20) which controllably gates on a triac (14) while taking into consideration a sensed current level.
