Problems with GMP075-03


Hi! Another furnace question: I have a Janitrol (GMP075-03) and the burners are not staying lit. I changed the flame sensor, but to no avail. It only stays lit for a second, then snuffs out. There is no LED code to correspond with this and the light actually just shuts off when the flame goes off. It does not turn back on - I have to flip the switch to get it to repeat.

Also, and I don't know if this matters, but the safety switch has been bypassed and one does not have to have the bottom panel on the unit for it to fire.

Thoughts?

If you have a vm.check ps is staying closed. Wire the door switch back. It's there for a reason

Changed out the circuit board last night and it worked. Hopefully this lasts at least a little while!
