philosopher and statesmen
We switched back to Rheem in 2010 because of this ICON issue and we have been very happy with that old style Shaw valve ....I've changed a lot of the Honeywell controls. I typically install Bradfords and I've had three of them go bad on me. One didn't work right out of the box. Thinking about switching to the Rheem pro units precisely because of the Robert Shaw controls. Very reliable.
But we are STILL going out about once a week and doing warranty work on ICON valves .. I keep 2 kits on my truck because it always seems to fall on a Satruday when the supply houses are closed...
