Abstract
A hot surface ignitor element is functionally checked for continuity and operating temperature. This check is accomplished by initially energizing the hot surface ignitor element and then switching it as a single ended element into a series circuit with a source of potential. The potential is applied between the hot surface ignitor and an electrode which is connected back to the source of potential. If the hot surface ignitor has come up to ignition temperature a flame rectification signal is simulated.
