Curtis your the man. Excellent repair.👍

[@HVACGUY]

Thanks 👍

[@uxwbill]

I can't imagine how hot that heat exchanger must have been. It was probably glowing red hot! Had it not been for the rollout switch, that probably would have ended in a fire. I know I shouldn't laugh, but I got a chuckle out of your dog having consumed a bottle of Scope. I can only imagine what a dog that's drunk acts like.

[@kg4muc]

Damn! What kind of idiot bypasses limits and leaves them that way? Wonder that thing didn’t end up like Chernobyl! I used to run into bypassed limits on trailer park oil “pot” furnaces occasionally. That thing had to be close to a melt down. Good fix putting it back safe!

[@jthonn]

We need to find the last guy that worked on that thing and have a discussion. You had to straighten out a mess there. Looked like spaghetti hanging out of there. I'm not a tech and know better than to bypass that limit. Nice work, and it did look more comfortable on the ground there. I just have to watch I don't lose tools or parts. Don't be too hard on Riley, he's still a puppy.

[@Bob.W.]

Lol. Good puppy. :)

[@SETX_Sirens_and_Rail_02]

This reeks of a landlord or fly-by-night tech special. That heat exchanger was probably glowing red hot by the time it shut off

[@KenKen-ui4ny]

Awful how people who don't know what their doing, or have no pride in their work. Can cause something like that to happen.

[@RayRay-nb7tn]

$5 part jumped out could've burned the house down, plus Cap Bandit left cap in box. Fuel to a possible fire. Good rewiring the motor and checking it out Curtis. Surprisingly the FD didn't call gas co to lock out the gas valve. Why are most of the houses you work on that the breaker box is outside not in the house? Is that common in your area? Keep those basic Rheem units going. Love those boys.

[@dfirth224]

In California all residential breaker boxes are outside. Many cities require them to be accessible from outside the fence for the meter reader. We now have smart meters.

[@craigbraswell4269]

If a tech bypasses a heat safety control, they shouldn't even have access to a thermostat

I bet the odor the unit was making when it was overheating, smelled similar to burning wires. That probably why the FD thought that what it was, even though there was more going on, then what meets the eye.

[@scophylio1]

You jumped the fan circuit out and the ac turns on, but I gather it’s heating season but your ac comes on when you jump the fan circuit. The person who played with the stat touched the wires: landlord or a friend of the landlord that dabbles in HVAC 😂

[@ThomasWalker-m2y]

[@dashcamandy2242]

🤣 Riley not only snacked on your glasses, his breath is now minty-fresh. 9 out of 10 veterinarians recommend Scope®! 1:32 - "Greetings, and welcome to Spaghetti Junction." I know I'm totally speaking to the wrong crowd here, but safety limits exist for a reason, and usually that reason is a pretty good one.

[@markjones7268]

Wow. Not the same, but a safety Hazzard. Neighbor ran over to me asking for help. Her husband was trying to install new electrical outlets while drinking. We sat him down and I Installed them safely. I’m glad you were there Curtis.

[@stevencossaboon3237]

Nice work Curtis. Man that one was a hack job.

[@RossTheGenMan]

Thats insane. complete disregard for the customers safety. Those type of people should be in jail not working on HVAC. The units where I work have a fan proving switch that won't turn on the compressor or furnace until the indoor blower comes up to a certain speed. I guess these units don't have those.

[@AllTattedUp13]

I have a feeling he's talking about a pressure switch and not the blower running, but inducer. Cause I aint nvr seen no sail switches and blower motors start b4 anything else.

[@Casal70]

Wierd glasses yes. But your other ones looked slightly big (wide) anyway, so maybe a good time to change. Black in top suits you, don't forget to test something really different. The technical rectangular shape is kind of boring. Great video, YT has stopped med to recommend your videos for some time. Now you are back, thank you and youtube.

[@rickr6908]

Nice fix. I've said it before, I am just amazed how these systems will still run if connected wrong. Reily likes alcohol amazing. What a little bad boy. Gotta love him

hope your pup is ok .. and not too hungover ... silver lining is no dog breath for a while I suppose

[@JW-bm4sb]

Excellent repair! Hopefully the last guy is not contaminating the rest of the neighborhood with shotty work, some serious liability issues there.

[@scotto3826]

There's a lot of joking going on about your dog and the Scope mouthwash. Unfortunately, this might not be very funny. These seemingly safe items for humans can be poisonous and cause serious problems for pets. I really hope your dog is ok!

[@kevinh6098]

you should wash the blower wheel on EVERY blower motor replacement. also on the new motor I would pop off the caps on the bearings and add extra oil to the bearings on those motors that I could. .MFGR'S tend to leave them pretty dry so that that the motor will fail in a few years

[@jackl9922]

Good1

[@Keith_Mikell]

great video curt. Why do techs leave caps in boxes. Are they too lazy to throw them away or is it a part number/logistics thing?

[@kevinh6098]

the worst that I ever saw was on an old boiler ...a plug in the relief valve and the limit bypassed. it was a bomb waiting to go off. handymen need to stay away from heating equipment !

[@paulhickey4485]

Lucky for them that was a pkg unit outside. I sure hope this wasnt a licensed tech that did that! Why would you not use tbe green wire to test and set up fan efkre checking the rest of the unit. Its a hard call to know whether or not to invest that much into a unit of that age witn such a catastrophin failure. Good job.

Better to be too long than too short. You can always cut to fit or tie up.

[@carloscastro7388]

Hola

[@wmcomprev]

When you changed from AC to Heat, would not the blower have stopped until the heat exchanger reached a specified temperature so as not to blow cold air into the house? As you showed, it started blowing again, but at the slower speed, after just a few seconds and so you weren't worried about it. I understand though, that just after changing the motor and fixing the wiring, you're thinking more about that than the normal operation shutting the fan down. There are high temperature limiters, but most furnaces appear to have low temperature limiters also. They also usually continue to run after the fire is turned off until they cool down the heat exchanger and not waste that heat, but blow it into the house. Correct? How does the motor determine the correct rotational direction on its own? I assume the correct direction, since that direction is actually moving air, will put a heavier load on the motor. Is that how it detects the direction?

[@AllTattedUp13]

No furnace has a "low temp" limit. You have your main/high limit, few roll out limits, some have a blower limit and some have a flu exhaust limit. And most oem motors are 1 direction only. Only time u get cw and ccw motors is with universal rescue motors.

[@wmcomprev]

@@AllTattedUp13 My furnace lights the burner. It then takes about a minute before the blower kicks in. It could be a timer instead of a thermal switch or it may have 2 thermal switches, one when the temperature gets up to operating range (enabling the blower & keeping the blower running after the gas turns off) and another for over temperature (shuts everything down), which is what was bypassed in this video. The first one is what I was calling a "low temperature limiter." I realize that's probably not the correct name for it. All the other motors I'd seen have to have the direction set on them. I wasn't aware of the universal rescue motors. Thanks.

[@AllTattedUp13]

@@wmcomprev that's normal forced air operation. Burners ignite burn for about 90sec then blower starts. It's done by time relays on circuit board, usually. And u can change them by dipswitches or cycling thru boards menu.

[@wmcomprev]

@@AllTattedUp13 I guess I'm remembering old units before they had circuit boards. They did the same thing, but used sensors. I'm talking real old, like 50 years ago. More and more the systems are controlled by the computer boards.
