Yep, my base unit lasted exactly 8 days, then it shorted out. The furnace repairman said he has seen it a couple of times, the base unit can't handle the current needed by the furnace so it goes poof. Back to Honeywell...

No replacement parts from Nest, my base unit died and I have perfectly working thermostat but am forced to buy a new one cause I can't get the base unit on its own.
