My furnace inducer motor on my coleman furnace keeps cycling on and offf in 6-7 second intervuls but it never lights I have a code for a pressure switch but the stores are closed and I need a way to A. test the switch and B. bypass it to work till tomorrow it's 58 degrees in the house and dropping and I need help quick thanks for your time

Also when I apply suction to the p/s switch the motr cycles but when it is disconectted at the switch the inducer motor will continuelly run it is clear at the orfice at the inducer motor

Blow threw the tubing on the pressure switch into the vent motor the is probably a blockage.

I blew through the tubing on the pressure switch to the motor it was clear the furnace was still acting up out of sheer luck I started shaking the tubing all about while it was connected to everything and now the furnace is working I'm guessing it won't for long any ideas would be helpful thanks for the post josh if any of what I said helps me fix this or anybodies ran into this before your help is appreciated

Look closely at the pressure switch fitting where the hose connects. Do you see a small hole, about the same diameter as a paper clip? If so, try wrapping a piece of tape around the fitting to block the hole. If this works, either the switch diaphragm canister or the inducer housing may have a leak. This is just a quick fix until the real problem can be corrected. I would not recommend bypassing the switch, even on a short-term basis.

If he does jump that pressure switch we might be reading about him in the obituary column in the paper. LOL.

Yessir, then he will be a candidate for a geo system... ;)

Lol hey gang a thousand thanks for the info I ended up tapping on the switch and it started working after the night I went and got a new pressure switch and they told me that coleman has had problems with the switch and lowered the resistance to trip it thanks again and yes we are all warm now

Glad you got it going.
