The seating of the connections might be the trick. I went out about an hour ago, unplugged a few of the switches, blew on them, cleaned them with a rag, unplugged the thermostat coil, plugged it in. Turned on the unit - fire up, click, click, click, then stopped with the light next to the switch. Said F-it - came in to check this forum, had dinner, went out a little while ago - working to perfection. Water is very hot, system was waiting for a drop in temp - then re-cycled on to reheat new water. Going to go on the trip - and if the thing doesn't work will get a $29 hotel for showers (we're boon-docking so it's less than a hook-up anyway). When this is all over I'm going to replace the unit with a gas/electric unit - which is what I should have had in the first place.
