Carrier furnace does not turn on Code 23 "Pressure Switch Did Not Open" I fixed it myself for free. 

I actually pulled my one line off......and blew into it lightly. Seemed like it dislodged something. When blowing (lightly) from the other end of the hose.....you should be able to hear the pressure switch click. Meaning it is working. Also have had issues with mine not staying lit. Check the flame sensor.....and if it still shuts off.....make sure that your pipes are not full of water from the condensation (like mine was). I just lifted up the pipe a couple of inches from inside the house and it drained any excess water to the outside at the outlet. Also make sure outlet outside is not free of ice. All has been good ever since. Nice video.

Thank you for the video, I have the same furnace however it was installed upside down. For the life of me I could not find the switch or a video showing its location, whoever installed it ran tubes right over it blocking it completly. Much appreciated.

Thank you, just fixed our furnace with your tutorial - you just save me money

Those silicone hoses are stiffer and less likely to kink when cold or at room temp but when they heat up they get more flexible and kink easily. As theyvget older they harden causing them to permanently adapt in shape according to the stresses normally applied to them, causing your kink. But generally the obstruction they are referring to have nothing to do with those hoses because they run on negative pressure created by the venturi effect created by the induction motor, which means that if your cold air intake pipe or your exhaust pipe get obstructed you will lose that venturi vacuum in those little pressure switch hoses you are playing with.... and no they dont have gas running through them so next time just pop them off one fitting at a time while your induction fan is running and use a lighter near the tube opening to see if theres enough vacuum to suck your lighter flame in. If not then try to shop vac your intake and exhaust pipes and see if it sucks up the birdnest or dead mouse plugging up your pipe.

You just saved me a ton of money. Thank you, brother. Happy Easter!

Bro I literally just squeezed the tube and it kicked on. Thanks man.

Thanks dude I took that hose off and there was spider eggs inside where it goes into. clean that out started right up

Mine was exactly the same as yours!! Crimped tube!

I would check the secondary on that unit. Bet you it’s plugged. The condensate traps on those Bryant’s tend to backup into the collector box as well.

wow i have the same furnace!! im going to check my tubes, next time im near it! thanks for the great info!!!

Kool good job that's a easy fix thanks Brotha

It's going to act up again. Theres a reason the switch stuck, and it's not because of that pinched tube. The pinched tube would make it a code 31, did not close. I think your control board has a sticking inducer relay.

I cant get to the first step of turning it off. There is no obvious power switch that I can find. On the left there is the gas line, no power switch, on the right no power switch as in your video, on the bottom of the unit there is a box, but no switch there either.

I’ve had the error code 23 happen a couple times this past week and have an HVAC tech out to do diagnostics but they havent been able to locate an issue and the error continues to periodically happen. When I turn off power to the furnace for 5 minutes it resets the code and the furnace eventually restarts. Does anyone have any idea what might be causing this intermittent malfunctioning?

Thanks man ! You save me 150 bucks .

Thank you.

Lol. Great minds do think alike

Check that secondary heat exchanger I Guarantee failure ..

Get to the damn point!!!!

You’re inducer is rusting out, probably rust in the tube 😂 Get this pod out of your house

Oh just guys? So as the female of the house that fixes everything, this video apparently won't work for me
