Description
Product Summary
The Robertshaw 780-790 is an ignition module from Robertshaw, described by the manufacturer as: hot surface ignition module HS780-17NL-104A & HS780-17NL-304A 10-812-17 100-00812-27. It is used with hot surface ignition systems.
An ignition module runs the ignition sequence on a gas appliance: it powers the igniter, spark or pilot, opens the gas valve and proves flame within a set trial time, locking out if flame is not detected. Typical signs of a failed module are no spark or igniter glow during a call for heat, a gas valve that never receives voltage, or repeated lockouts after the flame sensor, pressure switch and wiring have been checked.
