When replacing the base motherboard, removal from the wall is necessary and power to the thermostat must be turned off. The tools required are the blue opening tools, spudger, and a #0 Phillips screwdriver.

Before disassembling your Nest Thermostat, be sure that your HVAC system is powered off.

HOW do you disconnect the wires? I can't get them out!

Same here. It is like the springs are in a stuck position

I also can not dis-engage the wires. Feels like the springs are frozen closed.

Hold down the button on the end and the wire should be able to slide right out.

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.

I have no clue why people like their thermostats to the degree that they do.. I am both an A/c professional and an Engineer. They use what is called an SCR or silicon controlled rectifier for their switching instead of a tiny relay. An SCR is very sensitive to a spark or voltage spike. Yes the thermostat is pretty cool and has some nice features. It is advanced electronics but using SMC's or Surface Mounted Components?? . Maybe that would work well in a shielded component. But NOT in something that is connected to long external wires. The consumer bought warranty is only one year. I have seen too many issues in the field with their overpriced toys. Not having parts for this Chinese made thermostat? Priceless.
