Trane Wreck No Heat Service Call

[@Ted_E_Bear]

Great work, Rick ! RIP Betty White !

[@webluke]

Got to love the combustible material around the water heater. Not to mention all the other random junk around the blower units.

[@larryproffitt4729]

Really enjoyed this video. Thank you for putting in the time to make it.

[@HVACRSurvival]

Well I really appreciate you watching it and letting me know that you did like it! There's no way for me to know otherwise other than the thumbs up 👍👍

[@jrsmyth9761]

Thanks for the "Whopper Jawed(sp)"!!!!!! It's been a long time since I heard that from someone. Usually those Tranes check for open pressure switch, ramp up the motor to prove low and then high switches close(some will ramp down to open switches and then ramp back over high switch close), fire in high and then drop down into low fire(depending on the call, W1/2 and stat set up). Trans has also made it so if the board or inducer is bad you get a complete kit to replace board, inducer, hsi, wiring harness.

[@HVACRSurvival]

WoW, That's what I love about Trane....lol Thanks for the info!!!! Have a great night!!!

[@EverythingHVACR]

Looks like my last wiring nightmare, looks like trane is doing too much as usual as well great job Rick! As usual, happy almost new year

[@HVACRSurvival]

Thanks STEVE-O!!! You to man!!!

What a mess! Happy New Year Lora, Rick & Family! Best Regards! 👍

[@k.sullivan6303]

With all those maretted wire connections around that board and everything hanging, the vibration in the blower cabinet can also loosen the soldered connections where wires connect to the connectors on the board.

[@HVACRSurvival]

It was a flipping disaster 😂

[@johnwalker890]

Good job Rick, the maintenance man could've shorted out both circuit boards with those sequencer or relays, if you can show us the continuation of that job, would like to see you figure out the problem and learn some more, and Have a Happy New Years.

[@KarbonKopy]

Look at all those relays

[@vk3605]

The inducer motor stepping up in speed is normal to over come the pressure switch activation, you will see that often with longer flue piping on these model furnaces(good call on double checking the pressure switch wiring to make sure that was correct). Also the three flash on the control board is a general code stating that the pressure swithch didnt activate(could also be a falure but needs to be checked with a meter on the switch itself to see if the switch is closing). It will flash code three if the pressure switch didnt close, in this case the inducer motor didint run(because it was failed/unhooked) and the pressure switch didnt close and the board threw a code saying the pressure switch failure. Furnace 2: inducer motor started and activated the ignitor but there seemed to be no gas valve activation(couldnt hear it activate on video) and the furnace went into purge mode after the burners didnt fire and flame wasnt sensed. Could be a gas valve problem or board problem, should be checked with a meter to know for sure. I understand that not everything may be in the video so writing my observation based on the video. Happy New Year!

[@HVACRSurvival]

I wish I had the return trip, I thought I recorded it but wasn't able to find it. Everything was good to go. Thanks for the feedback, I don't work on a lot of Trane residential equipment.

Thanks Jason you too man! Stay safe tonight!

[@zacharyreed45]

Whoa dejavu, I had an ICP gas pack, lockout to pressure switch fault, never ran the draft motor.

[@lee-johnson]

You got to be careful with twins. I’ve seen several where one fan wasn’t running and the other was and the air just short cycles around and around and around gets too hot. They almost need Backdraft damper on top of the furnaces.

[@HVACRSurvival]

This was a state/city owned property that hires the lowest bidder. They got what they paid for..😂

[@throttlebottle5906]

round and round she goes, which high limit will open first, who knows. 🤣🤣

[@georgeian3243]

Too bad you’re left to deal with a no heat in a situation where the furnaces have been misapplied. Trane never allowed furnaces with VS fans to be twinned. I’ve never seen a relay setup like that. Trane uses a heat pump thermostat with outdoor temperature sensor to control add-on to fossil fuel installations. Needs a complete do-over. Thanks for the video…happy new year.

[@tbelding]

What a way to go out for the year, huh? So, when was the last time you did a PM on your own unit? :) Have a happy NY, and hopefully I'll get some flute work done this coming week or two, at least to get all the photos done.

[@HVACRSurvival]

I blow the trap out and clean the flame sensor usually every year and check the burners. The heat pump has a dual thermometer stuck in the plenum to watch the delta Tee for problems. Thanks Troy! Have a great night!!

[@philipstachyra]

If you are dealing with a pressure switch fault you should throw a manometer on to verify that you have correct pressure in the first place.

[@philipstachyra]

That applies to the furnace that the venter comes on and keeps stepping up. Many modulating furnaces have a calibration that is dependent on when the pressure switch closes.

[@HVACRSurvival]

The first furnace wouldn't run at all so there was no sense of getting a manometer out for that one, the second one dropped out on no code at all. Otherwise yes I would of used a manometer

Duel Fuel Circuitry, Twinning, Possible Water Damage, and Circuit Board Damage, and Venter Motor damage. It can be hard to wrap your head around all that.

[@HVACRSurvival]

Those boards were expensive 👍👍. I show the customer all the facts so they know I'm not trying to sell them parts.

[@Pskawt]

When you jump those trane double switches to need to power it up, wait a second then jump it. Otherwise they know your trying to trick them

[@HVACRSurvival]

The wire I had jumped was the limit leads that were on the draft motor. Otherwise your correct if it was the pressure switch👍👍

[@georgeian3243]

That installation is a total misapplication of those furnaces. Trane never permitted furnaces with VS blowers to be twinned. Never seen a relay setup like that either…Trane uses a heat pump thermostat with outdoor temperature sensor to control add-on to fossil fuel heat pumps. Needs a complete do-over on that job with properly configured equipment. Thank you for your videos, happy new year.

[@ianpalmer1482]

Wonder why there was a twin terminal on the vs models if they didn't intend for it to be twinned?

[@georgeian3243]

@@ianpalmer1482 The two-stage VS boards do not have a twin terminal, you might be thinking of the two-stage models with PSC motors. The main function of the twin terminal is to interlock the PSC blowers so they start together and run at the same speed.

[@HVACRSurvival]

The thermostat was a Honeywell 8000 dual fuel thermostat with a out door sensor. (Had Trane Label). The terminal said twin on the control board?, and that was a ECM control board? You might be right but this has been in for a long time now. They wont replace it until it dies. Thanks for the info!!

[@georgeian3243]

@@HVACRSurvival After reading Ian Palmer’s comment, I took another look at the video and yes, those units are two-stage with PSC blowers so they can be twinned. However, in my 18 years of experience with Trane, I never saw units twinned with heat pumps in our market of southern Ontario. Twinned with AC, yes. Sometimes you’d see two identical 100K units twinned with one 5 ton AC or a commercial 6 ton, something like that. The fact that no one other than the original installer has any idea what’s going on there is beyond ridiculous. Looks like the furnaces have been leaking condensate, maybe you’ve got a cracked plastic cold header or draft inducer square to round transition.

[@georgeian3243]

It’s coming back to me now. When using a 2H/1C stat, for example, you’d connect the twin terminals together and W1 to W1 on the twinned unit and likewise with W2. However, if current in the thermostat circuit was greater than the stat could handle, isolating relays across W1 and W2 were required. But in a heat pump application, can’t find any info. Hope this helps a bit.

[@christopherwalker8327]

There is nothing wrong with Trane furnaces if installed properly.

[@analogmoz]

There is nothing wrong with 85% of all furnaces if they are installed right. I have seen million-dollar houses with Goodman units with excellent ducting and installation and they run for decades without need for service. That being said, I like American Standard over Trane. More proven tech, less "customer is the Guinea pig."

[@publicmail2]

Now adays a one armed tech can service these.

Basically every inducer motor is plastic anymore.

[@HVACRSurvival]

It's a 92-92% eff condensing furnace, the flue gas comes out of the furnace in the low 110-150 degree F range. That's how all 90% plus furnaces are or they would rust out if they were metal.

[@k.sullivan6303]

This video was only 16 minutes long....I bet you were there much longer diagnosing and setting up the temporary heat pump operation adjustments. Then you had to do the final repairs after that. Must have been a hair puller!

[@HVACRSurvival]

I know that thermostat really well so that part wasn't bad, I've had several furnaces go bad and had to rely on the heat pumps before so that's nothing new but yeah since it was a Trane unit and I'm not as familiar with those so it did take a little longer, I was probably there 2 hours?
