No Heat Furnace Carrier Code 23 Pressure Switch

[@vishnureddy7456]

Thank you so much for this video! You saved me time and stress-I was able to fix my furnace in just 5 minutes. Now I have peace of mind, all thanks to your clear instructions!

Thank you much! Was able to get my furnace going at 2:30AM on Christmas morning. This video saved our Christmas!

Thank you so much! I am extremely novice when it comes to this stuff. I didn't check my hoses, which I will, but I just tapped on the pressure switch with my finger, and my furnace turned back on! Your knowledge is priceless!

Exactly the problem I was having - this was a great video, helped me fix my furnace in 10 minutes. Thank you!

I was getting code 2-3 as well. I work on pool and spa equipment, and most residential heater have a similar system. I was flummoxed because, even with my knowledge base, I couldn't figure out the problem. I had checked the vac switch and it tested fine... Or so I thought. What I didn't realize is that this switch has a dual switch configuration, where pool heaters only have a single switch. Thanks to this video and pointing out the dual switch set-up I was able to get my house heater up and running, which is great because it's cold outside, and was inside for a couple of days.

Thanks for the video. My Carrier furnace wouldn't start and I had fault code 23. Bought a replacement pressure switch from Supply House. The original switch part number was obsolete, but they had a replacement switch. The form factor on the replacement switch was slightly different. I made the appropriate connections and it worked. Thanks for the tips.

THANK YOU ! :) woke up this AM , no furnace, obstruction, fixed, error 23, found your video, blew air through the tube, gave it a tap for good luck... furnace is up and running . . Much appreciated.

Thanks for this video! Got a 23 error code, tapping on it with a screwdriver handle worked like magic!

[@jimmie3224]

Thanks so much for taking the time to make this video...I had a stuck pressure switch and you helped me solve it!

Thanks a bunch for this video. Woke up one morning to the cold and found that the furnace was not kicking on (even the fan would not turn on) but everything else did work. Made sure the thermostat and wires was not the problem first before seeing the board was displaying 23 (2 short 3 long blinks). Followed the video and checked the air hoses with no change then tapped the pressure switch (mine was a larger circular one.. look like it could hold a diaphragm) on start up and sure enough it spun up. Got to wait for parts but at least I know what's wrong now. Thanks for the vid

Thanks! Saved me a service call.

[@NathanielEberle]

This saved me a service visit and a bunch of money. Thanks!

I have a Rheem with a flaky pressure switch. Get it to work by leaving the vacuum hose attached to it and blowing/sucking till it clicks, or tapping it like you did. Good video.

[@KetoJames]

Should there be a plastic plug on the back port on the pressure switch? Looks like a needle.

[@RPostWVU]

You saved me, too. Would have helped if my code sheet wasn't upside down and I knew the 2-3 blink code meant 23 on that sheet.

[@forlingchan9237]

Thank you so much. The video and the explanation are truly helpful.

Having issues with condensate yes it can cause that condition. One thing I find is other techs don’t clean the trap, gotta drain, worst case rotting the secondary. Always part of a yearly PM that most don’t do.

[@anhemta6979]

Great video with 👍 details . Many thanks.

[@helixfunger642]

my motor was running. thanks for those that this helped though.

Humidfier for carrier furnaces

[@dazdarren9926]

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?

[@luckyamo15]

Mine has the same code except mine won't even "purge" the first fan doesn't even come on. But it's flashing the same code

[@jaimecantu2611]

Hello, did you figure out your problem on furnace as mine is doing the same?

[@luckyamo15]

@@jaimecantu2611 I honestly don't know what I did, but it started working again. This was last winter and it's been working since.

[@jaimecantu2611]

@@luckyamo15 Thank you

[@croyal4240]

You might want to drill that pressure port a little bit bigger , otherwise it will plug up with condensate again

[@BillyN31]

Noooo don’t do that! They are designed to close and open on a certain amount of water column. You could jack it all up. The solution is to clean your condensate drain hoses and trap.
