Rinnai R53i damaged from power surge from utility power
A power surge from a neutral being disconnected at the xformer when my neighbors tree fell has damaged several items in my home. We lost the control board on the furnace, an alarm clock, malfunctioning water filter and the Rinnai won't work. Here's what I know so far: The R53i has an optional wired control "remote" and it was dead. Consumer tech support (as much as allowed) advised to disconnect and retry. I still have no water and no attempt to ignite when water is flowing through the unit. I looked in the paperwork and the obvious thing seemed like the surge protector, but I checked the terminals for continuity as described and I do have continuity. I checked the glass fuses and they are intact. I realize a component on the board has failed or perhaps a sensor but I wondered if anyone could advise of any other common things to check and the procedure. I am somewhat familiar with electricity but no electronics expert. I am trying to repair myself to save money and I always find that I do a better job than paying someone else. I've had a remodel business for 12 years but I don't have a sub that I know personally to hire this out to but I did make contact with a local Rinnai certified business which I will go to if this is too much trouble. Just wondered if anyone had any tips/tricks on what might be wrong. I appreciate your time.
