Einleitung

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.

    • Vergewissern Sie sich vor der Demontage Ihres Nest-Thermostats, dass Ihr HLK-System ausgeschaltet ist.

    • Fassen Sie den äußeren Metallring des Displays mit Ihren Fingern und ziehen Sie ihn direkt von der Wand weg, wobei Sie den Sockel zurücklassen.

    • Denken Sie daran, das HLK-System und den Thermostat auszuschalten.

    • Trennen Sie alle Drähte von den grauen Federkraftsteckern. Dies kann mit den Fingern erfolgen.

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

    Beverley Brown -

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

    Bill Redfield -

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

    Bill Redfield -

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

    Amber -

    Yes, the button on the end of the wires is stuck in the down position. Tried pushing with my fingers and several smaller tools- they appear to be frozen in the down position.

    Garet Ten Cate -

    If you hold the buttons down while pulling the wires, they'll come right out and the button springs reset.

Would like to know where I can get just the base motherboard.

wesbug -

Where can we purchase replacement parts?

brettspradley -

i want the baseboard.. where i can buy? pls help...

john gemora -

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...

bbolen -

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.

Adrian Ma -

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.

Hey Jon, I’m trying to repair my parent’s 2nd Gen Nest. It sends out “heat” and “cool” signal at the same time. Anyway I can replace a component on the motherboard?

Lizik -

Good post. Wish I had read before I got a Nest thermostat. What would you recommend as a good alternative? I hate when you can't replace simple components and parts cheaply and quickly. What the !&&*.
