Advanced Service Saver™ Diagnostics

Guardian pig heaters also include a unique, built-in Advanced Service Saver™ diagnostic feature that simplifies troubleshooting and helps keep your heater running when you need it the most. 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.
