Rheem Imperial 90 Plus not igniting.
Symptoms – When heat called for: tries to fire. Over and over a click from a module on the control board (ST788C1002). A green flash comes from the module on the control board that is clicking.
Ignition Control Module – Honeywell 47-22481-01 – does not give any LED indications at all - No blinks at all on the LED on the Ignition Control module.
Blower working fine.
Sensor has been cleaned with sandpaper. Ignitor appears to be fine. It was replaced about 3 years ago. Heat Exchanger replaced about 10 years ago – warranty. Burners replaced about 5 years ago. I have photos taken today ready to forward if they will help.
