    Gibson Inducer Constantly Running
    Hi All,

    I have a Gibson gas furnace, and am having issues with the inducer. As soon as there is power to the furnace, the inducer starts running and doesn't stop until I cut power. The furnace will go through 1 heating cycle. But won't kick back in for a second cycle when called for. The error I'm getting is the three-blink "pressure switch closed, inducer off" even though the inducer is running.

    I've checked the pressure switch, and it's fine. I've checked the vent safety switch, replaced drainage tubing, adjusted the angle of my vent pipe (about 10 ft across the basement to outside wall), and put in a new thermostat. Nothing. Any thoughts?

    I just noticed I need a new - I think what I need is the plastic orifice ring - between the inducer and condensate box. This one is a little fried, probably because (originally, I thought this was the entire problem) there was a dead mouse stuck in the drainage tube running to the condensate collection box. Unfortunately, I can't find anywhere to get one.

    Thanks to any and all who have advice to offer!

We have a Gibson central air and heat pump. Blower quits and unit outside freezes up. If we turn it off for a while everything works okay for a little while. Is the relay switch in the blower motor bad? If so where is it located?

Thanks for taking the time to read the post. This is a trane xr90 gas furnace. The inducer fan runs constantly. The unit will run and meet the set point on the thermostat and then shut down except for the inducer fan running. The unit will not start again unless I manually reset the pressure...
