First You See It, Then You Don't

One of our two-year old 40HI heaters was tripping the Ground Fault Indicator breaker once every two weeks at first, but we could reset it; then gradually it conked out more frequently until, at the end, we could not revive it. After the company troubleshooter could not come up with a fix, we purchased a new computer board. Meanwhile, while waiting for the part to arrive, we tried one more time, out of frigid desperation, to switch on the unit, and, to our relived but tense surprise, the temperature red light lit up and has been on ever since except once, and our hot water supply has been just about uninterrupted. So, we never opened the box with the new computer board, and cannot give a review on it. However, there is a sense of security knowing that inside the little card-board cube which is gathering dust in the corner of the attic, that if one of the original units finally do breathe their last spark of BTUs, there will be a resuscitating transplant to pick up the pace.
