Hello! I noticed that you had the positive port of the manometer hooked to the - Side of the switch (more of a vacuum ) . And the negative port of the manometer hooked to the + side of the switch that connects to the burner box which is atmospheric. For ur differential. Is that a mistake ? Or does it not matter ??? I’m a new technician out of school and I am constantly running into pressure switch issues and I am trying to really grasp what readings I’m looking at and what readings I should have 100%. So I am not just guessing

enjoyable to watch ...

You can tell an instructor from a KZread service Technician. A technician will usually slip in something bad about Goodman, because Goodman doesn’t pay companies incentives like some other brands. An instructor will teach you that if you install a system correctly, they are all good

Arrived at service call. Wiped top cabinet with a rag. Conclusion: its goodman

I've found the water column rating for the pressure switchs on the actual schematic in small writing in some cases.

Just replaced a pressure that was BAD. The replacement just gave me problems after a week of working. Thoughts?

Great video but now I'm dying to know what was the blockage!

Im wondering why on a new install why sometimes priming the drain trap is needed so the pressure switch makes but then the same issue is present when the trap is clogged..🤔

Thank you for your great content & sharing your expertise with us. But 1 question I have that I've wondered is, say the furnace goes through its sequence and starts heating. What if the pressure switch opens back up after it's already started heating, will the system shut back down or will it wait until next start up cycle. Thank you so much again.

Can you wire a pressure switch backwards?

Could you do a video about correctly hooking up manometer hoses in line with pressure switches? I always get mixed up.

look up "acservicetech pressure switch" and "gas furnace component history"

Hey my friend. I’m still going to purchase a dual manometer but without it the furnace does everything. Cfm on, pressure switch closed, HSI lit, burners on with a flame sensor, then off 4-7 seconds.

Sounds like flame rectification, board or pressure switch but you would need to test each function individually, thanks

hi, so on the + side of the pressure switch the vacuum is created through the heat exchanger? is this correct? thanks.

Great video. I've been doing HVAC for a 30 years 33 to be exact and have never had a really good procedure on very tough pressure switch problems. I work for a school district now and don't have to deal with it as much but we still have some furnaces there. How did you figure out it was the induction tube by your pressures that you were reading? Cuz they both right about the same. What I've done in the past is I've just disconnected both the supply in the exhaust and see if it would come on to see if it is the exhaust or intake piping. Real good video and I know it's going to help me in the future but how did you figure that one out by just looking at those pressures that it was the intake?

@acservicetechchannel

5 жыл бұрын

You are right, I just opened up the combustion air inlet and the pressure changed. Also, when the inducer is high enough to allow the pressure switch to close and the intake is just as high then you know the problem is on the intake or heat exchanger side, thanks

If you can’t suck right , there’s not much air to push ! Like if you put a box fan against a wall , you won’t get much air flow on the outlet !

One small questions . I get the pressure switch hose that runs directly to the inducer . But right here I see it hooks up to the gas valve then goes to the burners to just have a hoe inside the cage burners . ? Why ?! Can you please explain throughly . Thank u

@acservicetechchannel

That is so that the atmospheric pressure at the burners remain the same as at the gas valve so there is no problems with the flame or at the pressure switch!

Sweet. Look forward to your videos! I get to be the first comment 😋😀
