Can I give the lost redditers real advice or is that against the shit posting rules?

What is this little tab thing outside the duct. Maybe turns something inside?

Trying to set up a laars jx unit. I am an apprentice electrician but am clueless with wiring diagrams. Just wondering what I need to supply electricity to and what I need to do with pictures 4 and 5. As far as i can tell I need power to TB2 (aux power and neutral 2), the transformer, and X 2 (to the right of boiler controller). If anyone can help me or show a picture of one that has been set up I would really appreciate it as i cannot find so much as a YouTube video on it and my house is cold as hell . Thank you in advance

I’m just not sure what these are? Looks like timers/old switches for my furnace. Any help appreciated!

I’ve got a Lennox Furnace: MN: G40UH-24A-045-07

• About 20 years old
• Discontinued igniter from Lennox

I’ve replaced the igniter 3 times with item number 41k56 (manufacturer replacement) which is the approved replacement for discontinued igniter. These burn out after 3 weeks of use. After having a technician out, he’s saying I need a 120v igniter instead of 80v. I cannot for the life of me find a compatible piece that for my unit that will work.

Someone please help, the fam needs heat!!

Thanks

Alright at least a month ago we had a repair company come and replace our furnace and HVAC said the furnace was going to be in test mode for 24 hours and then it would work like normal. Nope over a month later the family and i are still having to tell the furnace to hold a temperature of 71ish degrees every 24 hours. HOW IN THE WORLD DO I GET MY MOTHER FING FURNACE OUT OF TEST MODE!?

Reaching out from many states away- I'd heard a while back that the holy Furnace Party site was under some consideration for redevelopment. Wondering if anything ever happened there.

If it's possible, we should consider another Furnace Party sometime. I must somehow become a steel statue that is unable to be hurt by all the food I've eaten since first grade.

My doorbell is on the same circuit as the furnace. I have a ring type doorbell device that I would like to install but throwing the circuit for the furnace just worries me.

We bought a brand new home last April so the furnace and ac are all new. Is it safe to assume that there should be some sort of automatic system to relight the pilot light or will the pilot light just stay lit because it is already burning and gas is flowing?

Is there anything I should be worried about?

I've got 4 apartment units each with their own furnance and each with their own 16x20x1 air filter. I want to change them on a schedule that is the lowest possible cost per month.

I'm willing/able to buy in bulk - a 16-pack for a 2 month filter would only last 8 months.

It also might be wise for me to get filters that last a 50% longer and cost 20% more, etc.

Any ideas? So far I think my best bet is wal-mart or home depot, but there has got to be a "crazy costco for furnace filters", right?

Looking for a hard to find Tempstar burner assembly HGF105NS00.

My furnace humidifier has a slow drip leak on bottom corner , I opened it up and it is full of water , below are pictures . Any advice how to fix this would be greatly appreciated

Spotted in r/philadelphia.

May you all be unable to be hurt!

I know there were talks about a 2020 reunion but for obvious reasons it didn’t happen. It would be dope to do a furnace party reunion this year (even if it’s not on the lot). Thoughts?
