Just noticed when up in attic today, havent noticed it before.
Even with the water off, the fan in the tankless heater keeps cycling on and off. Cycles on for 1 second, off for about 5, back on for 1, off for 5 and so on.
Its been doing this for about 1 hr all ready with the water off. Im guessing its not supposed to be doing this that long after the water has been off? Its a new unit about 4 years old, no history just moved in a few months ago. Its a Rinnai RL75. Thanks for any advice!
