Thank you for the video. Greatly appreciated. I have a carrier furnace that is getting the same code. Just wondering if the ignitor was glowing on the one you were working on, prior to replacing the valve? On mine, inducer motor appears to be working, and the igniter works (tested). But, when the furnace normal process is started, call for heat by the thermostat, inducer starts, but the igniter never starts/glows. the end result is error 35. Indicating either a mainboard issue or the gas valve. Just strange that the igniter is not trying to work, although it works when put in component test mode. Getting ready to test to ensure 24 volts to gas valve. Thanks Again Greatly Appreciated!! Definitely got a sub from me.
@@MiHeatingGuy Thanks for the fast reply. Yes it does come in from the top. Also for some reason I am not reading 24volts to the gas valve, unless this furnace has some type of precheck prior to sending the 24 volts. I did use the green/yellow, and blue per the manual but still no volts. Just curious if you received 24 volts during your test. Well anyway. Thank you so much for the quick reply, getting cold here LOL. Have a great night. :)
One thing I have seen happen on a few different brand furnaces his year is the blower deck is not sealed tight to the side cabinet and when the blower runs during ac mode it creates a negative in the upper cabinet and draws humid air through the intake pipe and it sweats on the inside of the pvc and runs into the furnace. Have seen it multiple times this year. To test I turn blower on and run a lighter where the blower deck meets the side and if the flame starts pulling down then I will silicone the whole edge.
+carl neuman this is a very good point and I will have to investigate this further what I will probably do is turn the blower on shut the door and hook a manometer into the intake to see if I have negative pressure really appreciate this tip thanks for watching appreciate the comments
I’ve had 3 of these this week for work from water dripping on the gas valve from the intake pipe best to put a piece of metal over the gas valve to redirect the water
Hi, when you locked the furnace in low heat to adjust the manifold pressure does it fire at low stage immediately? Or does the furnace fires at mid fire first for around 40 seconds then ramps down to low fire? Thanks
Very Interesting. I have an Infinity Weather Maker installed 2004 I believe. Never had to do anything to it. Makes me nervous. What should I do other than the obvious vacuum dust , check water draining, filters.
Follow the troubleshooting manual and check all of your AC and DC voltages on the wiring harness. You could have a bad contact on one of the connectors causing all of the problems. I've found this to be a problem with motor ecm modules....third tech, from third compay ...problem fixed in 20 minutes including testing! Your DMM is your best friend :). please don't use a cheap DMM. Fluke or Glaser are my goto meters for precision readings...AEMC had been growing on me too...French..Who would of thought! I do have to agree with having negative pressure from blower compartment causing LOW PRESSURE issues as well as ignition faults. the infinity is probably the easiest communicating system to work on...does Trane even make its own communicating proprietary control/thermostat yet?
Soap box thermostat on a MN not a good idea unless it’s a version 24. Intake on top of furnace bad idea. The intake pipe is condensing in the summer due to Venturi effect and dripping on gas valve. Best furnace on market when installed and set up properly.

Gas valve needs to be replace. does the combustion air come in at top of furnace. if so it needs to be moved

Thanks for the tip! Will do that as well.
Wanted to thank you for the advice!! Changed the gas valve and started right up. Thank you sooo much. Greatly appreciated.
I put dielectric grease on the pin connections to protect from moisture

Interesting looking foward to the answer on the code issue
What if the ignitor not lighting? And your getting this same code. Wouldn't it be the ignitor? I'm not to familiar with infinity units
just got a case of Code 35 on the same gas valve. but the HSI isn't coming on and there isn't power to it. any lead?
already replaced a blown fuse

You have to reset the chip and the code will pop up
👍😎
costs the customer labor! $$ lol. you can check the pressure drop across HX.
It's busy times out there.
+Nor-Cal Refrigeration & H.V.A.C yes it is 12 to 13 hours a day
the problem with this furnace all I can say is Ameristar Ameristar LOL!!!!!!!!!!
+AirOasis Mechanical HVAC Ameristar those furnaces are for people that can't handle a real furnace LOL who makes that Goodman
American Standard makes those furnaces.
So it's like a trane wreck without the Trane lol
