Great info. I had to call customer service to help to swap out my 1930s original thermostat with a digital one. Sadly only had 3 wires and only 2 in use. Colors did not line up and customer service was rather hesitant to help.
I have this exact model and I'm trying to figure out why my screen went blank. Fan part works but the rest of the system stop working and the screen won't come on anymore even with fresh batteries
Fucking epic man, totally saved my ass, came home at midnight to it being down for not sure how long, this will get me through the night till i get a new thermostat in the AM
When the house reaches the desired temperature, is it better to disconnect the wires at the thermostat (rather than turning off the switch at the furnace), so that the fan can continue to run (if needed) to cool down the heat exchanger? In other words, wouldn't turning off the switch at the furnace potentially allow the heat exchanger to remain too hot and be damaged?
i was wondering the same. im distraught sometimes by the lack of replies to questions like this. im learning a wish people would provide more feedback and just open ended statements you know
Only ever do this with a conventional furnace, and in an emergency, to keep your people, pets, and property from freezing while you get a thermostat in there ASAP. Not with a heat pump, not with an electric baseboard. Really need a strong warning on this video, people get in over their heads.
Curious as to why since I just connected this with an alligator clip between R and W and the wire melted. Also tried a connection between R, G, and W to get fan + heat but nothing happens and there might've been a spark when connected to R at that moment.
I doubt this will be read, but is there a way to install a thermostat on a mini split system? These seem to be all the rage these days but appear to be reliant on battery operated remotes to fully function. I have seen some that allow smart thermometers but do not want to put anything like that on the home network, for sure. It also generally would be more practical to have a direct wired connection on the wall over a small remote to probably lose.
Depending on your brand, they either have hard wire stats available specific for the mini split in question or some even make adapters for you to be able to hard wire in any conventional thermostat. Just need to search for whatever brand and model mini split you want/have and see what they offer
I'm fine with diy-ers. They try to do something like this and forget to turn off the unit and pop the fuse. Or worse, as happened last week, a dude popped his fuse replacing his thermostat, didn't have one, so he wrapped wire around the fuse spades, and when he powered the furnace back up, he hadn't actually fixed the short, and it blew every low voltage connected part of his system from the furnace board, to the defrost board (it was dual fuel) to the new stat. So, yea....keep on keepin on, diy guys! I gotta feed my family! 😂
Yea, the white wire tells the board in the furnace that you need heat. So the control board makes sure the heat and fan both come on when white is powered.
My thermostat is a th146-n-u/u and only have 2 wires at the box upstairs, then all the wires are downstair bolted to the heat furnace and there i can see the red and green one. What should i do?
I would love to read the comments from actual electricians on why it's so brilliant to bypass and just connect things together. I love to see you doing dryer repair.

you probably figured it out by now,, but just for others sake. in this situation the control board on the main unit will switch the fan/blower to on after initial start up sequence. i am assuming this is a gas system with a digital board at the main unit/furnace.

As an HVAC technician, I would not recommend doing this for AC. The thermostat keeps the system from running nonstop. Running your AC nonstop would cause the Evaporator to ice up and stop working all together.

@@abelhernandez9710 no, I under stood the concept, right now my thermostat is messed up and I have no heat. I could do the same but it would be 100 deg by morning.
Please add a disclaimer.. turn off the power to your unit before you touch the wires before you take off the thermostat.. just in case someone jumps the gun.. Flip the switch or breaker on your furnace!
Yeah I mean but even before showing the inside of the stat and poking around in there. Just thoughts because people don't know what they could mess up 🤣
Please note: This is not for a heat pump! Also do not touch blue and red together. Please call a professional! The B and O terminal control the reversing valve.

Thank you for this. I should have been more specific in that this is for a GAS FURNACE. There are other steps involved with heat pumps and other systems. Thanks so much for the comment. Like he said if you have concerns of doing this wrong please contact a professional.
Curious as to why since I just connected this with an alligator clip between R and W and the wire melted. Also tried a connection between R, G, and W to get fan + heat but nothing happens and there might've been a spark when connected to R at that moment.
This would have been good to know in February of 2019, when the damned batteries in the thermostat died Saturday evening and the shops (that had AAA batteries) didn't open until 09:00 AM Sunday.
This happened to me a few years ago. I immediately switched everything in my house over to NiMh batteries and keep a charger with 16 AA and AAA battieries ready to go at all times plus backup batteries. Very useful!
this doesn't work with communicating systems like Lennox s-200 to s-400, etc. also, take care to pay attention to the label more than the color. you can easily switch to a different color for any specific function. Lastly, the O wire turns heat on in conjunction with the Y wire. In some cases, you'll want to energize the O wire at the same time as the Y, and in some cases, you just want to energize the Y. In my specific area, it's far more common to energize the O in cooling. The white wire is often used in the O slot. The O is used for heat pumps.
Lol this is big joke in my household. My wife in college lives in such a shitty house that when the heat broke the landlord had them touch the wires together to kick the heat on all winter.
Oh man, that was similar to the level of my property manager in college as well. We had one of the toilets with a completely rotted out subfloor and a roof leak that led to mold in one of the bedrooms 🤦♂️
We have electric baseboard heaters as a backup for wood heat, and the thermostats for those are switching full 240V AC. They could be connected the same way, but you'd have to turn the breaker off, and treat it like you treat a light switch rather than this lower voltage control circuit. You'd also need to check the voltage and current rating on your connectors.
You could just wire it to a light switch so you can turn it on and off. This isn't all the best idea. If you are in a pinch just twist the wires together. Don't think many home owners will have those push fittings laying around.
I would never teach a homeowner this even in extream situations. Just to many things that could go wrong. And when they do who are they going to blame. Definitely not themselves. I am a service technician and I would never put this information out even if you have good intentions.
Duh. This isn’t a permanent thing. This is literally just manually turning it on. I think everyone knows it isn’t going to turn itself off without a thermostat.
You've just created a constant call for heat. If you leave it like that the house will get as hot as the furnace can make it. You need a thermostat of some kind!
Funny......first....Simple honeywell thermostat ???.....I still got the simple , round "mercury blob level thermostat"....(lol) ................second....Whay was there no display, why was your "simple honeywell thermostat" not working..??
Not all thermostats are the same meaning you can’t operate them without thermostat face on and not all units are the same and will not work without secondary heat or emergency heat and most reversing valves can’t being energized without O and R so yea which by the time you’re trying to figure it out you will most likely cause a short popping a fuse then it’s time to call someone… so yes don’t listen to this hack because I’ve seen it multiple time, trust me call a professional.
@@rickbo3366 haha it’s hard being in front of a camera! This is for an emergency situation, and most people who are using this information understand that. Thanks for your comment. Real… real uh helpful. Yea
Brilliant idea don't call a professional. Go ahead turn that on!! Don't follow this guy's instructions, folks. Call an HVAC company to fix the issue. If the thermostat is off, you have a problem.
At least around me this is not uncommon on things like a rehab project. Drywall crew removes the thermostat, weather takes a turn, and now you can't find the thermostat to get the heat on. This is obviously not a permanent fix.

Nice, so the fan is just fan, and the furnace control board will also turn the fan on and off?
Yes, the blower fan will turn on once the burners are lit and heat exchanger has some time to heat up.
Yea, the white wire tells the board in the furnace that you need heat. So the control board makes sure the heat and fan both come on when white is powered.
If you want to run the fan by itself, you would just connect the fan wire correct? Also, the 24 volts is DC, correct?

@@rickbo3366 haha it’s hard being in front of a camera! This is for an emergency situation, and most people who are using this information understand that. Thanks for your comment. Real… real uh helpful. Yea
@@diyhvacguy well I’m sorry, I understand and I apologize for commenting “informational” information.
Brilliant idea don't call a professional. Go ahead turn that on!! Don't follow this guy's instructions, folks. Call an HVAC company to fix the issue. If the thermostat is off, you have a problem.
At least around me this is not uncommon on things like a rehab project. Drywall crew removes the thermostat, weather takes a turn, and now you can't find the thermostat to get the heat on. This is obviously not a permanent fix.
