Hey Sam.. I have a Trane XR 90 that was not starting up. it was giving me 3 blinking lights, which indicated a Pressure Sensor issue, like u mentioned in the video. I followed your instructions and pulled of the tube and blew into it. I also cleaned the location where the hose comes out of the switch into the main unit. I tried turning on the furnace again and BINGO it started working. The burners came on and heat was getting pushed out. Thanks for saving me a service call and $$$$$.
you probably dont give a shit but does any of you know of a way to log back into an instagram account?? I was stupid lost the account password. I appreciate any help you can offer me
@Eric John i really appreciate your reply. I got to the site on google and I'm trying it out atm. I see it takes a while so I will get back to you later with my results.
I was grumpy and cold (It's winter in canada) followed the video and now I'm grumpy and warm. I am incredibly greatful for the quick and easy video instructions.
negative 9 outside tonight in central mn and its 545 am. 30 min ago I woke up with the house at 52 degrees. I watched this video . very gently blew and sucked into the disc thing. hooked it back up and it worked!!! will replace valve...…..well my smart wife will make me call a pro. thanks for video
Hey Sam. I got up this morning, Christmas, and the house was 50°.climbed up in the attic and started taking the furnace door off. Noticed the three flash error code. Look that up and found out about the draft pressure switch. Your video showed me where it was and I fixed it with a drinking straw. The technician was on his way after a long long day. He was impressed that I got up there and fixed it. He said he doubted we'd have any more trouble with it. He said something as small as a piece of cobweb could cause the blockage and the switches very rarely go out. Thanks much.
Mr. Fix It, you're a genius......I followed your advice at on my XV90 and cleared the pressure switch tubing.........Works like a champ now.........THANKS.........
Hello just want to say thank you the sucking and blowing worked :) !!! I had my furnace and vents cleaned but after the company left my furnace would not turn on, I followed the panel and seen the three flashing lights and found your solution and it worked :) Thank you so much!
Echoing what the others here have said. Pulled the tube, blew/sucked on the tube, blew/sucked on the port, connected back up. WORKS. I'll note, most of the particulates I cleared came from the port going behind the fan wall. Not much came out of the tube connected to the sensor. Thank you sir.
@@MrFixIt-jl2xc What kind of crap are you trying to spread or spew with this baloney about the Trane XR 90 pressure switch? Sucking or blowing in the tube does absolutely nothing the only fix is to run with the tube disconnected from the pressure switch which clears the 3 flash error code and then it might run a year or so and then bust completely forever and them buy a new furnace that isn't Trane and throw the old furnace into the nearest lake. Trane furnaces are the worst furnace ever made.😁
Thank you so much! I have my furnace running again at 3:30am and 35* outside temps, with 60* inside! Brrr! I'll have the whole unit serviced as soon as the Thanksgiving holiday weekend is over.. well, at least I'll try and get an appointment asap. Now that it's not critical, maybe I can sleep again! Thanks again! You're a life saver and a Holiday saver today!
Thanks to your video I was able to fix problem with my furnace pressure switch error. Line to the pressure switch had debris in it, I cleared it and furnace works fine.
Wow ! first reset the system- Trane err 0079 (low air pressure switch opened) message came back. Completed the process in this video - regarding the sensor tube. The code was cleared and system is back to normal operation. Thank you Sir !
update- after several days, the code returned...turns out there is a slow leak of freon outside below the compressor. Again thank your Mr. Fix-it. I made thru several days.
Good short video. Thanks Sam!. To the point and short (esp. when you are sifting through the possible issues and trying to figure out what's causing unit to not work in bitter cold)
My furnace kept turning on and off. I reset the power and it worked for a few hours and then went back to messing around. I followed this fix and it worked. Been running all day, thank goodness.
thanks for the video man, i take the small blower out to check for debris or something and what i found was a dead bird inside the blower case, and thats its, the furnace is working perfect now
Thanks....gotta love RU-vid....saved me $$$. I followed your instructions and gave the pressure switch a suck/blow....amazing furnace works fine now!!! Thanks again...you were the second video that I looked at and the one that made the most sense.
I has a three blink error message on my Trane XV80 furnace. I tried the things you recommended on my pressure switch. It started up after a brief waiting period. I had battery corrosion in my thermostat that I thought could have effected it’s functioning after 20-years. I installed a new thermostat and reprogrammed it. It will interesting to see if the furnace follows the program and turns off and on normally to the desired temperature settings.
Happened to find a way to fix the problem without having to open the unit. I have a Trane XV80 and experienced three red blinking (unit won't start) problem once in this summer and once in this winter (today). In summer problem, it refused to turn AC on. On thermostat, I turned Fan from 'auto' to 'on' (Fan 'on/auto/cyclic' switch) while set it to 'off' on thermostat System 'cool/off/heat' switch; the fan started and let it run for some time. Then I turned thermostat System from 'off' to 'coo' and the cool air coming. Then turn Fan from 'on' to 'auto' and it continued working. In winter (today) case, it refused to turn unit heat on. This time, I tried it again and happened to turn both Fan from 'auto' to 'on' and turn thermostat System to 'heat' at the same time. And the noticed the hot air came later. After it was fixed, it ran good until it happened again after about six months in my case. I still don't know what might cause the problem. You may use the following procedures to try your luck: - Turn Fan (on/auto/cyclic) from 'auto' to 'on' and System (cool/off/heat) to 'off'. You shall hear the fan started and air flows. - Keep it for about 5 to 10 minutes. - Turn the System (cool/off/heat)from 'off' to 'cool' or 'heat'. - Wait for another 5 to 10 minutes and monitor if the AC or Heat is coming. - If not working, repeat this procedure several times. In my case, it took me about three times and then the AC/heat started unexpectedly at some time. I may be able to improve this procedure if it happens again in future. Share my experience here as it does not require to open the unit. As everyone's problem can be quite different, you may still need to try what "Mr.Fix it" showed in this video or need a technician. Anyway it's good to give it a try as your first step.
Thank you so much. Blowing into the hose that’s connected to the pressure switch fixed my problem. Do you suggest I get that pressure switch replaced as soon as possible or should it all be okay from now on? Heat is working now. Thank you so much
Hey Mr. FIX It. Thank you so much for the vid, it helped me get my furnace running. I did what you said and it led me to discover a bunch of mouse debris in the air intake tube. And as for the dumb arses pointing out uhs. In your tutorial they probably fixed their furnaces using your info and are just ungrateful cretins L0L..Thanks Again....

One thing I didn't see mentioned is the tubing on my Pressure Switch was getting soft, 15 years old, and had a loose connection to the switch. Replaced the tubing and that was the problem. Available at Big Box Stores usually in 10ft lengths. Cheap fix!
This video is only half accurate and can be dangerous. Most of the time if a pressure switch is failing there is an underlying cause. You could have a a blockage on the fresh air. You could have water in the collector box that the pressure switch attaches to. The inducer motor could be clogged. You must be very careful here! Bypassing or blowing into a pressure switch can cause damage to the switch! Remember it's a safety switch and your life or your families lives could be at risk. Call a professional and don't risk it!
