Furnace fun !!

[Aerovette]

Every change of season it's the same shit.

Beginning of summer is spent doing AC repair and beginning of winter is doing heater repair. :mad:

I turned on the furnace last night since it dipped in to the 40s. Nothing.

I have a spare control board and a spare flame sensor...so I installed them. NOTHING.

System cycles on, the evacuator (?) blower turns on, the igniter glows orange, the gas turns on, the burners light...and in 5 seconds it shuts down.

Typically this is a flame sensor issue...but I just put a new one in. I took it out, wiped it down with alcohol in case it had residue from manufacturing...same thing. 5 seconds the system shuts off. I took the old one and cleaned it with a Scotchbrite pad, and bent it a little to be closer to the flame...same issue.

All grounds are good. Two spare boards do the same thing. In total I have swapped in and out, three circuit boards and two flame sensors with the same results.

Any ideas? (Not ready to call the guy yet)

Call the guy :yesnod:

The pressure switch which references the inducer isnt "making" when the system starts.
Could be the condensate trap isnt primed, a bad pressure switch, clogged tube, bad (slow) inducer fan motor, or other.

if you pull the tube off the pressure switch and suck/or blow on it when the burner starts, the contacts make and the burner should continue to run. suck or blow depends on setup.

[Egnalf]

Its not the flame sensor.

[Aerovette]

Call the guy :yesnod:

I don't have an eyeroll large enough to adequately reply.

You ROCK !!

I disconnected the hose and saw that it was cracked. Cut the split off, and blew and sucked the line and I could feel and hear the switch cycling. I connected it back up and it is WORKING !!

Well done sir !!:clap:

[Big bob]

:iagree: with the pressure switch but it might just be doing it's job. Get up there and look for a blockage might just be a birds nest or a roof rat got stuck. On mine I can pull a piece out at the furnace for inspection and cleaning. To old to risk roof hopping. :seasix:

Also does your blower fan for heat not exuast turn on? If not replace that capacitor. If you can once it fires up flix the squirrel cage with a stick to get it moving.

My heater identifies as an AC unit in the summer so it's "woke".:D

[Big bob]

So a quick blow job was the answer. :rofl:

[Murray]

So a quick blow job was the answer. :rofl:

It cures all issues :yesnod:

[Aerovette]

So a quick blow job was the answer. :rofl:

Apparently.

I know that when I get one, I am trouble free for a while. :Jeff '79:

You can etch that one in stone. :yesnod:

[Bill]

Its not a tumor.

:iagree:

[Bill]

My heater is fighting against cold supremacy, so it's "woke".:D

:iagree:

[Shrike6]

That was the exact thing that was wrong with mine last winter. Cutting off the cracked end of the tube fixed it.

[Onebadcad]

Hmmm, so furnaces are a real thing, HTH would I know that?!?!?

Damn Nephi, are you turning into the Dude???????:wtf::wtf:

Put a mask on and open your wallet:)It's time

[DJ_Critterus]

Call the guy :yesnod:

He should have tested the system weeks ago and called the guy then :yesnod:

We do get winter here in FL, but only for two weeks and they are not made of 14 consecutive days :yesnod:

I did. 👍

[MadInNc]

Did ya shut off the breaker?

[DJ_Critterus]

Did ya shut off the breaker?

No, and it probably ruined his good engine stand :funnier:

That's why so many fat, lazy dumbasses choose to live there.:seasix:

[Big bob]

Ever notice how ignorance is self supporting? :leaving:

[Aerovette]

No, and it probably ruined his good engine stand :funnier:

Space did not allow for an engine stand, but I'd like free up the vice holding the hose on if I could.

[Egnalf]

Very common issue. Good job fixing it.

[Stangkiller]

So you blew your heater to turn it on and it worked…there are just so many ways to take this.


Glad its working though!

Florida has two seasons, summer and February.
