The ignition control module in Guardian heaters is self-diagnostic. If a problem exists, a red LED light on the module will flash a specific pattern depending upon the problem that is diagnosed. If the light flashes, the flash pattern will be followed by a pause and then a repeat of the flash pattern until the problem is corrected. Flash patterns are provided in the heater service guide.
