Xb1000 trane ac... The fan unit outside runs constant, even after a new contactor installed.. any help?

Something, possibly low voltage wires might be shorted sending power at all times to the contactor, or maybe start at tstat,, disconnect the yellow wire which should be sending signal to ac,, does it still run?

I do have same issue, bought new condenser and new contactor, but still same issue. Contactor is open but fan still turning and when AC starts fan start turning opposite direction.
Please help

I had a tech check it out. Found the fan motor was bad. I am going to replace motor to see if it fixes the problem.

Please let me know, if that will help I will do the same
Thank you so much

The fan motor is bad! About $75 for a new one

Good, for you, motor for my AC unit is around 130.00.
Will order tomorrow.

No way a fan motor should cost $130 plus inless it is some special 2 speed motor, or is a huge motor.. What size ac you have?

This is what I have:
AC Unit: 7B0030B100A1
Motor: MOT08895
1/4 HP, 20/230/60/1, 1100 RPM, TYPE PSC, 42 FRAME, CCW BALL Bearing, 5.0 MFD @370V

Thank you for your help

What brand is it?

American Standard INC. Unit made in 2000
Thank you

That's why, trane and american standard are way over priced, you should be able to pick up a universal motor for around $65 to $85 Brands like a. o smith

But how to do cross reference and will it fit my current unit? Shift size for fan, screw holes..
What generic brand would you recommend?

Thank you again

Fan motor replaced... runs great

A "bad" motor won't run continuously... it's the control that was the problem. Someone misled you on the cause of the problem... then charged you for something you probably didn't need.
