I have a Quadrafire 1200 freestanding, It has no vacuum. I have cleaned the stove from top to bottom, new control board, and changed the vacuum switch and hose, but when I bypass the vac switch it runs flawlessly. Is there something I am missing? Where could I be losing vacuum?
Yes sir.... I have a handheld vacuum pump for applying vacuum on cars. I'm a pretty fair mechanic, but this stove is my nemesis.....
Is the hose nipple on the stove clean?
use a wire like a paperclip to check it. Are the door seals good dollar bill test
