Where is model number located normally on this furnace.
Sorry no model number that can be located i have looked in the past and I do apologize . Why am I now not getting any gas to ignite?
Where exactly is the pressure switch and how can i get it functioning again it was working until I pullled hose to inspect
Okay i have located it now what would be my next step
Okay just detached it all from back wall of furnace cleaned it all out checked for blockage and found none and no kinks in hose.
I was able to jump the two and got it to fire up.
Can I go online for that I do have an account at R E Michaels but I dont think the would carry that specific switch but i have had luck on ebay for boards and other related controls. Now just to let you know the entire reason why I was even messing with this furnace was because the new surface ignitor I installed wouldnt always ignite. What control is bad or going bad to not tell that glow plug to turn on every time heat is trying to kick on. Ive been watching it . For the most part it fires up on its on but every now and then it wont and will go into lockout mode with 1 blink from the board.That was really the answer im chasing until I ran into this other problem with this switch.
