Have a york 90+ upflow 100,000btu natural gas unit, won't fire unless I pull the tube from the combustion motor leading to the pressure sensor and put a vacume on it then it will fire and cycle, any suggestions ?

Straighten a paper clip and poke it through the nipple you pulled the hose off. Check for blockage in flue pipe.

Do not run the system by bypassing the inducer motor.

Don't listen to MarkwithaK. He's a variable-speed motor basher.:D

True. But I fully support people NOT killing themselves.

When I pulled the hose off before I blew into it to do just that, numerous times and I thought it was clear it never dawned on me to put something down into it

Anyway you saved my wife and kids from a cold night and for that I owe you a debt of gratitude I appreciate your advise and I will pay it forward. Maybe someday I can do the same for you

Merry christmas

Dang It you gave away the paper clip trick.

Damn man. How are we supposed to earn a living if you keep giving out our 'trade secrets'?

With everyone going green, less paper usage means someone has to come up with a use for all those damn clips!

Um hello... paper clip necklaces.

Damn, that reminds me, Christmas is comin' up!

Um hello....paper clip necklaces.

Ever since the eco-safety-tree-hugger crowd got rid of the original removable soda can pull-tab, I've resorted to using paper clips to decorate with. Don't know what I'll do if they get rid of those. :)

Egg shells ! You can color them and their recyclable

Hello guys,

I have the same issue, same furnace too. I have, for now, gotten it to stay lit, but the air is not hot, its luke warm at best. How can I increase the temperature of the furnace? Its 58 degrees in my house, and the air coming out of the vents is about 70 degress F. Any idea how to adjust the gas pressure screw either? Thanks
