I don't think that its a matter of just taking a few pins out as the unit isn't even attempting to idle. The fan that is stuck in a constant state of "On," is the larger fan on the bottom of the unit.
I'm not familiar with your unit. However, when it comes to the fan on a oil, gas, etc. unit, it doesn't matter if the circulation fan runs 365 days a year. All the fan does is circulate the air. The fan on many newer units won't simply shut off till the temp inside the heat exchanger is lowered. If you have a full carpet of glowing coals, maybe that's why the fan won't shut off, or even slow down. Sounds like you have a feed problem to me. The combustion fan is supposed to run all the time. Is something wired wrong? Or has the furnace been running just fine, and all of a sudden acting up?
