Last night was below zero here in Frozen-Over-Hell, a.k.a. Michigan.

As I walked by the Nest thermostat in my hall last night at 3 AM, I noticed that it it up with a message instead of the temperature the furnace is set to - this was unusual. I read the message.

It said the Nest wasn't getting power from the furnace circuit and that the furnace would be shut off. At 3AM. Below zero out. There was some gobbledegook about wires and blah blah blah. This message went completely over my head. I had no idea what to actually do.

I walked over to one of the heat registers, and sure enough, no heat. I checked the circuit breaker box. It was still in the "on" position. I walked into the furnace room, and tried turning the furnace off and back on. Nothing.

Was it time to panic, ladies and gentlemen?

You bet your sweet ass it was time to panic! It was time to freak out in a moon age daydream!

So I tried to figure out what the thermostat was telling me, tiny letters, scroll through a little window; still too arcane. I went to the web, to the Google site. Everything seemed vague. But after doing some reading on the site, I recognized an error message I got. There seemed to be a bug or problem with Nest thermostats in extremely cold weather.

Bingo! I'll follow that link.

Funny, I've had this thing for several years and we've had cold weather, but whatever. I go to the appropriate troubleshooting page and start the process.

By now it's close to 4AM and it's getting cold. I'm now on the verge of jumping out the window but it's:

(a) too cold to open a window and jump out; and,

(b) I'm on the first floor. So there doesn't seem to be much point in standing on the window ledge and making the jump.

And may I remind you, ladies and germs, there's no one to call at 4 AM. You are on your f#cking own at 4 AM!!

I am terrible at fixing things. I always wind up calling a professional. But at 4AM, in below zero weather, knowing everyone with a furnace is probably having problems and no one's coming out for days (my wife's sister and husband lost their furnace and it's still unfixed), I'm desperate enough to try anything!

One of the pages said to remove the Nest's bezel and disconnect the "Y" wire or wires on the Nest's wiring panel. I remove the bezel and get to the panel. There it is. The Y wire. I can tell because it's attached to a little box-looking thingy labeled "Y".

Be careful, it says. You can screw the pooch and destroy the entire universe if you do this wrong! Gaaaaaa! More panic sets in. I now re-read everything a dozen times and memorize it.

It says shut off the electrical circuit to the furnace to prevent shocks. I run downstairs to the breaker box and do this. I run back upstairs to the offending thermostat. I tug at the wire. Damn.

You can't just pull the damn wire out or unscrew anything to loosen it. There's a gizmo that releases the wire. The instructions do not tell you what that gizmo is, or how to release the f#cking wire!

I've never used one of these gizmos, and am not sure where the trigger is located, but I figure maybe it's like replacing a wall switch and you press something with a screwdriver to get the wire out. I have a vague memory of that.

At this point, I have nothing to lose. It's now close to 4:30 AM. It's getting chilly! I press what looks like a little tab next to the thing that holds the wire, with a screwdriver. Nothing. I press harder. Nothing, absolutely nothing. This time I figure, WTF, if I break something, there are hotels.

I press really hard. Eureka! This time the wire comes out.

The instructions say to use electrical tape on the exposed wire to insulate it so there won't be short circuits. I run around looking for electrical tape. There isn't any.

There's shipping tape left over from my guitar downsizing. I figure I'll use it and replace it with electrical tape in the morning. Better than nothing! I do that. Then I replace the bezel, run downstairs, turn the circuit breaker back on, and...

Let there be Furnace! And there was Furnace.

And The Great Gods of Emergency Repairs saw the Furnace and that it was good; and The Great Gods of Emergency Repairs divided the heat from the cold.


By now it's 5 AM. I got down on my knees and said, "Hosanna!" Then I hit the sack. Today I got some electrical tape and did the thing to insulate the wire.

Oh, disconnecting the Y wire also disables the air conditioning. But at 0 degrees, that doesn't seem to matter TODAY.

At least I now have time to have someone who knows what they're doing come out, go through the system, and I'll decide whether to have them replace the thermostat with a newer model. Maybe it won't have the same problem.

Friends, Romans, countrymen:

I came not to hit my Nest or my head with a hammer; I came to brag about my unanticipated and unlikely ability to solve a simple problem that would have vexed no one else! Yep. I made a repair in an emergency. Felt. So. Good!

😂

Mine went out with a power fail a few nights ago .. my lower floot still won't get above 58 .. but that's WAY warmer than outside.

It's wierd when the hand rail on an interior staircase is ice cold , as are the walls.
 
So funny! I read your experience through, laughing at myself the whole time because I had a similar happening just days ago, though mine was semi-self-inflicted.

Sorting through 100 web sites, with 99% of the solutions either not applicable to your issue or flat wrong, and all the while your in-house temp continues to drop as your wife watches you uneasily… it is such the relief when you cobble together a solution from the bits of info that actually gets you going! In my case, I discovered the breakers (3 pairs of them) have to be powered on after a generator test in a certain order or the air handler won’t recognize the outdoor unit. Life in the “everything is a computer” age.

I’m glad you got it going! Any repair that gets you going is a good port in a storm. Nice Bowie reference to boot!
 
I got confused by looking at a thermostat at 3:00am. I can’t imagine ever doing that.

Good job solving the problem, even if I wouldn’t have know about it for a few more hours. I have a spare Hudson’s Bay blanket for use if the house ever gets cold.
I've had to do that. I was worried about pipes bursting, etc. So I really wanted to find a fix!

I was SO relieved!

Bowie reference! I can't think the words 'freak out' without adding 'in a moon age daydream'!
 
We put a new furnace in our house 18 years ago so I'm just waiting for that day to come.

In the mean time......when our power goes out and our generator kicks on I turn on most of the lights in our house.........because I can.......AND when our furnace goes out I'll remember all the times I was ahead of the curve.....
 
I had a Nest a decade or so ago. It wasn’t a good experience. I had the ring that the wiring attaches to fail twice, which seemed stupid. How hard is it to get the least complex part of the widget to be reliable?
 
My in-laws had a similar problem with their Nest thermostat. Although I can't remember the nitty-gritty of it.

Glad you got it fixed though!

In years past, I might not have understood why you'd be awake at 3AM pacing the halls. Now I've experienced the eternal, and recurrent, awakening of having infant and toddler children, which I fear a man never recovers from. Thanks for the good times, circadian rhythm, I'll remember you fondly.
 
Cozyness and warmth correspondends.
Don't put your capability to respond under the carpet.
And additionally to entertain with self irony after a situation that brought you to own limits and beyond (because your SOP is not DIY).
I clap virtually your shoulder writing: Well done, Les!
 
Well done sir. We pushed our cold across the atlantic after a few weeks of unpleasant weather (below zero centegrade, high humidity, no sun and jusr fog). Would have been very disappointed if my heat pump or my thermostat woukd have given out...

Good luck everybody in the american continent with these temperatures. We are back to normal
 
I have a colleague who’s Nest thermo went on the fritz. He opened it up to find a spider had fried the circuit board.

He was quoted a ridiculous amount to replace the thermo brand new. He managed to find one at much discount.

Lesson - don’t rely on a stupid box of gizmos to run your heating.

I should add, the rest of his system, boiler, rads etc. was perfectly fine.

At ours, last week I’m sat in the living room and hear a “drip, drip, drip” coming from the downstairs hallway.

Water coming from a light fitting.

Exploration revealed water coming from the boiler upstairs (we don’t really have basements in UK very often).

Boiler off, water off. Call the heating engineer.

No heating/hot water for 24 hours. Luckily we were having a milder patch of weather.

Turned out to be a control flow valve for the hot water supply. (In the UK we commonly have a boiler that combines heating and hot water)

Our Heating Engineer is an amazing guy (big shout out to him), he turned up at 4pm the next afternoon, got everything fixed. No extra charge.

Being cold in the home this time of year is so miserable.

Well done Les.
 
I learned that I've been putting off moving somewhere warmer for too long. 😂
The OP was written in a very humorous manner. I was smiling while reading it but also thinking how many times I have been in a similar situation and was not amused. I hate to tell you that when you get to somewhere warmer it becomes the AC that you end up with issues with. I finally replaced my whole unit in October of last year.

The people at the AC company I use have asked me on multiple occasions if I work in the industry because I have told them what is wrong with it and how I know it is that by the troubleshooting I have done. I actually got pretty good at troubleshooting it. I wish I could have just bought the parts and did the full fix myself.

Mine always seemed to go down right about bed time. What a pain. It went down on me like a day after I had my stents put in. I was outside vacuuming out the drain line with a shop vac within hours of getting home from the surgery. I ended up leaning against the outside unit asking myself why the heck I was out there doing that. It was late and it would have been an additional charge to get someone out there and my wife was of no help at all. It is not fun being in that position.

I am glad you got yours up and running. I lived most of my life not that far from where you live. You do not want to be without heat in the dead of January or February. There will be expensive to fix damage to your house if you are.
