Great video. I worked on a pressure error for several hours over three days. After watching the video a second time, I thought I should check for a hole in the pressure switch line. The tube was pliable, semi opaque and only about 5 inches long. It looked to be in good shape. I could hear the diaphragm open and closed when I gently blew or sucked on the tube. I checked the continuity on the electrical prongs when I sucked, then blew. The switch was opening and closing. Then I looked very closely for a hole in the vacuum line. I didn’t find one, but I did finally notice a very small, light colored, dead insect in the line. I could barely see it. That was the problem!

Ended up that icy snow had gathered in my intake for induction motor blocking the downward pointing pvc pipe. Thanks for helping my brain to realize the issue. Merry Christmas!

Had this issue about a month ago. It ended up being the fresh air pipe. The fresh air connected to the exhaust and I put a piece of screen over the exhaust because a bird had built a nest. Well the fresh air was pull heat because of screen. So I disconnected the 2 at the "Y" joint and ran fresh air separate. No more issues. Thanks for all of your videos

[@stellarheatingcooling2689]

You welcome I have a question what will happen if I install bigger compressor in a walking cooler or a air conditioner thank you

[@acservicetechchannel]

Though I haven't had a circumstance where I had to install a larger compressor for the system, I would just say, that it won't work with a fixed orifice but with a txv the low side should work at normal pressures. Remember that a larger compressor will need more refrigerant passing through the motor winding area to cool down and more oil return for lubrication so both of these will be lower since the txv will adjust the flow for a smaller system. The current will be higher just do to the size. Other than that, not sure but once again, not sure when someone would really be in a circumstance where they need to oversize since you can match hp even if it is not a direct replacement, Thanks and Merry Christmas Stellar!

[@DVGuy2]

Always informative Videos and step by step diagnosis! Thanks again!!!

[@acservicetechchannel]

Thanks L Brown!

[@morganne23]

Good video, informative, dont forget sometimes its just a bad board in general. I had a Trane 80% yesterday no variable speed. Verified pressure switch was closing and remaining closed, no blockage, inducer was on, verified voltage and what inducer was pulling, and removed exhaust to bypass to see if it was blocked and if it would still happen, still getting “pressure switch error”. Ive also had a few furnace control boards immediately give a pressure switch code and the board itself not sending any voltage at all to inducer in the first place, I think you mentioned that. I was taught it is rarely the pressure switch thats actually “bad”

[@parkerbohnn]

It never the pressure switch itself its usually the intake pipe and or the exhaust pipe is clogged. For me I can't unclog the exhaust pipe so I run with the tube off the pressure switch. Trane furnaces are living proof it doesn't pay to save a dollar.

[@morganne23]

@@parkerbohnn I have had a couple bad pressure switches that got permanently stuck before but very rare.

[@parkerbohnn]

@@morganne23 I just run with the tube off the pressure switch. The pressure switch is good the motherboard just got replaced and the motor is a new replacement. The exhaust pipe is 25 feet long and there's some blockage at the furnace no way to get rid of the blockage at the furnace where the exhaust pipe meets the furnace. All the vents outside are clear. It's a piece of junk XR 90 Trane furnace from 2004.

[@morganne23]

@@parkerbohnn lol yeah I just had like 2 feet of birds nest in an exhaust and intake but the run was so long I could only hook the nest in the intake. I told them to get a duct cleaning company to get the exhaust cleaned out. Not to mention inside the pvc was under finished ceiling. Im not dealing with that. It was a 90% Lennox... the ones put in by contractors in new construction homes that usually end up leaking all over off the inducer.

[@matthewkrueger9319]

It's the first "cold" day of the year and hot air was not coming out of the vents. Spent the good part of a day thinking my pressure switch was bad (31 error code) and tinkering with many things. Watched this video and decided what the hell, maybe item number 1 (clogged exhaust) is the culprit. Went outside to look - lo and behold a bird had built a nest in the exhaust pipe over the summer! Took a wire hanger apart and used it to pull lots of sticks and nest particles out of the exhaust pipe on the side of my house, then jacked the heat up using the Ecobee thermostat app on my phone, and glorious air started rushing out of the exhaust pipe. Went back inside and the house was warming up. Thanks so much for the tips! Is there some kind of screen one can put on the exhaust to stop this from happening, or would that be a bad idea? Dryer vents have those plastic mesh covers, it seems like this large pipe is just begging for a bird to nest here every year.

[@parkerbohnn]

My problem is the exhaust pipe is clogged at the furnace and the pipe is 25 feet long so I can't unclog it.

[@psdubl07]

We had AC installed a few weeks ago and starting 2 nights ago we're getting error 45 on a Rheem high efficiency, gas furnace, which means the low pressure switch is open when the inducer is at high speed. I/m not sure but it seems more than a coincidence that this started happening just a few weeks after the work was done. They sent a tech out to check it, and he said the problem was probably the line clogged because when the furnace was installed (about 6 years ago), they (diff company) ported it out into the ground, which he said could get clogged. He cut the pipe so now it just empties out onto the ground and got it running again. A few hours after he left, it errored out again. The after hours guy came, fiddled around, checked the pressure, clogs etc...checked some of the connections and such, and got it going again saying that he thought maybe the previous error code hadn't been cleared out. It was running, he left, only to have it error out again after an hour or two. It will still run, but just blows cool air out the vents. Anyone have any ideas about why it would run for a bit, then error out and shut off? I feel like some of the things covered in this video aren't the culprit becuase then it wouldn't run at all. Thanks!

[@dominiquepierre916]

[@gwinters6847]

I came across one new bdp unit that the inducer molded plastic had a malformed seam near top of mating surfaces to heat exchanger... just enough leakage to operate pressure switch on the lower end of break, make point. I lost hair that day . ha. NEVER stop learning!!

[@googlesux666]

I'm stuck on error code 32. I think it may be a bad control board as I don't think 120v is going to the inducer motor. The molex connector where you have your leads stuck in is where to check for 120v, correct?

[@andysullivan7226]

Had one with the rubber hoses going to the condensate drain, relief port box the relief hose was clogged with grey like stones/dust, we PM the furnaces and flush out the box, the condensate box would flush out so to say, the rubber tubes are alittle hard when we always inspect them, then this one time I squeezed the lines like I do and the tube in that spot busted open and water went flowing. The relief tube and upper drain tube where clogged with this grey stuff and was eating out the rubber. So I always pull lines and check now. The call was for water on floor. No sign of water any where, nothing in condensate drain and never leaked water when I was there. Also noticed alot of water coming out of exhaust, which I known something was not right. Fixed the tubes and perfect now.

[@acservicetechchannel]

Nice thanks Andy!

[@arsent8326]

Can a too low or too high gas pressure also cause this? I have a newer icp hvac and it throws 6 flashes, turns off once or twice a day i have to shut the power off wait few mins then turn it back on and it works again. Unit is about 1 year old. I have 2 of the same units 1 of them works normal

[@EGGINFOOLS]

Thanks for the detail. I have a trane xv95. After 3 seconds of the burner lighting it cuts off. Tries 2 more times then 2 red light flashes for retry lockout. Flame sensor has been cleaned and inducer motor was changed due to bad bearings. Funny thing is that if I pull the vacuum line from the burner box and slightly blow in it when the flame lights i can hear the pressure switch click and it'll stay running every time. It has a dual pressure switch setup. I think the switch is bad.

[@parkerbohnn]

I have an XR 90 Trane and as everyone knows they're the worst furnace ever made. I just run with the hose taken off the pressure switch. The pressure switch works perfectly the motor is a brand new replacement and the intake and exhaust pipes are 25 feet long apiece so I can't suck out anything. So I run with the hose off the pressure switch.

[@willscott3327]

I was on the second floor of my home when I heard something abruptly spin down. Apon investigation I was getting the 3 light flashes then pause. I could feel cool air come through the vents but furnace wouldn't fire. Through troubleshooting I started blowing into all the tunes that were in the path of the pressure switch. I also blew into both ends of the pressure switch and I could hear it clicking. When the author of this video said a bird nest could fall down the pvc stack connected to the inducer motor I decided to check. I found a 3 inch piece of wood lodged down into the enducer motor. Once removed my furnace fired up.

Great video! Very helpful. I had a problem with mine were the installer did not route the drain line properly after it left the unit. Do you do any videos on proper drain line installation or problems. My furnace drain and ac condensate drain were combined before a p trap which was against York’s recommendations and it cause the furnace drain back up after long runs. So I would get intermittent pressure code errors. My hvac guy changed out both sensors and and wanted to change the board next before I said time out. I was surprised that my guy did not use a manometer to check the actual sensors and instead just wanted to start replacing everything since the parts are cover under my York warranty, of course i pay for the labor.

[@mandalyn6895]

So my heat stopped working and I have watched a ton of videos on it. Love yours it’s great!! Lots of good info. My question is this tho. I seen on another video that the number one issue is a dirty flame sensor. So I took mine out and furnace fired right up. Next day same issue. Then I realized that it has error 31. Decided to clean the flame sensor one more time just in case it worked again. It did! But now I’m in the same boat again and thinking I need to replace the flame sensor. Am I wrong? Or should I focus on the possible causes for the error 31?

[@uptownphotography]

I have a Goodman 80% model Horizontally mounted unit in attic saying via the code that the pressure switch is stuck open. I could use some advice/input how to proceed and what to check next. Note: Inducer motor works, but no ignitor turns on. (I replace the Flame detection sensor thinking that was the issue because last week the furnace did not work and then started working normally again for about 4 days. Now it's not working again and as mentioned blinking that the pressure switch is stuck open...Thanks... Phil NYC Area

[@tommartinez62]

I got an error code of three flashes on my 12 year old Goodman furnace. Jumping the pressure switches did not work so I started testing them , flame roll out sensors, etc. They all read good, the only thing left at that point was the circuit board. Replaced that an we are golden. Error codes are kind of a joke with furnaces. If the sequence of events are interrupted that is where the error code seems to flash to.

I had a problem with the pressure switch not opening after last cycle, I took switch off and had continuity between com & NO, I noticed a very small amount of water inside switch, after getting the water out and no continuity between terminals I reinstalled switch and The furnace started and ran fine. how would water get into switch?

[@reedkwize1]

I have an American standard freedom 80 hat only furnace and I have the pressure switch error code. My furnace will start, the flames would come on and before the blower motor kicks in, the furnace starts cycling ( inducer motor stops then stops) then the code comes on. Help!!!

[@acservicetechchannel]

On an 80% unit, it is usually the hole where the tubing is connected at the inducer cloggs, the pressure switch is bad, or the exhaust pipe has a problem. It could also be a cracked heat exchanger but you may notice the flames rolling back if that was the case. I use my SDMN6 to check pressure switches. You can also read resistance across the switch with multimeter set on ohms to see if when it clicks closed if you are getting close to 0.0ohms of resistance. I just checked one on friday that was reading 300ohms so I knew the pressure switch was the problem, thanks

[@reedkwize1]

It’s not the pressure switch, I have two furnaces and I swapped the switches and the switch worked on the other furnace. Sometimes it will go as far as the flames coming on, and before the blower motor kicks in, it starts to cycle.

[@reedkwize1]

Thanks by the way🤙🏾

[@MVPProductionsBeats]

I had a pressure switch open while inducer is on code. I don’t have a manometer but I checked the tube from switch to inducer it’s fine, I cleaned the port on the inducer that the tube connects to and it’s fine. I tested the pressure switch and it was working, I was getting 24 volts right before the inducer vacuumed it and closed the switch then goes down to 0. However at one point I started getting a low voltage at the pressure switch while inducer was on, I was seeing about 5 volts which was strange. Furthermore at another point the code was on and I was literally measuring the switch at that point and it was fine. I changed the pressure switch because it was fishy. However the problem happened again but then it stopped. My only other assumption would be the control board.

The drain tube coming out the bottom of the furnace at the pea trap I took the water drain hose off and its sucking air in to it Is that normal or should it be blowing out?

The carrier inducer internal wheel typically doesn't break compared with other manufacturers. Is the wheel hitting water constantly in reference to how the furnace is pitched?

@@acservicetechchannel The drain and tubing were vacuumed; I watched your video and did it again (great video-very easy to understand), but still having the same issue.

[@acservicetechchannel]

You should be checking the pressure switch with a multimeter to see when it is closed or open and if 24v is crossing it. If there is no problem there and the board is saying that there is then the board would be at fault but you would really need to take your readings at the pressure switch first, thanks!

Anyone else have issues with 90% Nordyne furnace tripping inducer limit all the time? Its my own furnace, not a customer. I have cleaned the secondary (even though it wasnt really dirty) the A-Coil, always change filters, slope on exhaust is fine, etc... it is not an under sized unit, nothing blocking any vents, blower wheel cleaned, the weird part is, the collector box stays pretty cool. Wondering if it is possible it is smashed behind the collection box. Also, read somewhere that restrictor plates inside the inducer on some have been known to fall off or rot. Not sure how true. Weird part is, once I cleaned the A-Coil, it stopped tripping the limit for the remainder of winter (it was January) once I cleaned it, it stopped and heated beautifully. Like 6 degrees in 40 minutes no tripping, then, following winter (this year) started in again) you cant tell me the A Coil re plugged that fast. Especially with how well I cleaned it.
