Question about Rinnai RHFE-556WTA Direct Vent Heater NG Air Conditioner
Most modern gas heaters use a code system to tell the operator what the problem is. look for a pattern in the flashing, and then compare that pattern to the literature on the inside of the heaters panel. When you have a diagnosis code, you can follow the appropriate course of action.

Call Rinnai. I have replaced about 15 control boards that have an issue rating with the capacitor microfahred rating. There is no recall, but if you at least let them run your EXACT MODEL AND SERIAL number you may be pleasantly suprised that they send someone out to replace the board.
If you have a dual port digital manometer and are handy, you may be able to install a new board. You MUST reset the high and low fire rate with the new board. Hope this helps
