Do I unplug the wires to each and check them both within that one minute before it shuts down? or do I leave the wires connected?Easiest way, is to put your meter across each switch while the inducer is running, and see which one isn't closing.
check small port on inducer where hose from vaccum connects...my be clogged and make sure hose in open and not kinked........ make sure exhaust is open as well
Thanks, I have seen different test on the Internet. Some say to pull the power wires from each P S, attach meter and start furnace. Others have said leave power wires connected.You don't have to unplug anything. Set meter to voltage and check across the switches.
do the test that is easy for you ..both should tell you the same thing...Iam not dogmatic...just want to help you.check the other things mentioned and will go from there...Thanks, I have seen different test on the Internet.

I will have to make some extensions since these 2 older PS's have the connector blade deeply recessed.
Is the unit installed horizontal?2 Green lights on panel, top green led one is blinking 2 times bottom is solid green
Am I reading that this is a pressure switch issue? correctly? How do I tell witch one?
Same results! Yes all of the orifices were gently probed! :biggrin2:ok did you check the small port where orange tube from pressure switches attaches to inducer...remove hose use wire or small drill bit by hand and gently push it into the port to clean it out.....another thing to try remove split hose and do the .30 by itself see if it closes then..
thats an 80% furance..those ports clog alot....and restrict the vaccum...
did i miss that ...if you can hear the switch pull in and click when inducer starts an you are reading ol ....yep agree replace that pressure switch...sorry
while ebay is a pretty good place to buy and sell...be very careful of used hvac parts......you could try jonhstone supply...if you have one in your area...No problem, I am going to replace both. There is one on ebay that is identical, but I may try a local place Century, tomorrow and see if they will sell to me.
I need 42-24166-06 for the complete assembly!
