Reznor ft75 garage heater wont ignite flashes 3 times
 
My Reznor ft75 wont fire up.It does not have a pilot light. It has a code that flashes 3 times.I tried jumping that part with no success. I know most of these have reset buttons,but i can not find it. It has been working great for years! Any ideas?

the flashing lights are supposed to be a aproblem in the pressure switch,jumped it and it made no difference.

Port on draft motor maybe plug if flute pipe is clear.

No its not suppose to be a problem in the pressure switch. It means there is a problem establishing proper draft through the furnace.

As said earlier, check the flue pipe, pressure hoses and ports for obstructions.

Is the Draft motor even running?

You guys are good! The draft motor is moving very slow,barely actually. So it is not pulling vacuem to close the switch. Now i have to figure out where to get one.Thanks fellas!!:thumbsup:
