Blower motor turns and stops very slowly but never starts

I have a blower motor that turns 2 cycles then stops and turns 2 more cycles with a jerking motion.

All voltages are correct. High and Low

The Motor has this on it.
X13 FM19 E100625 8/28/13 10 01GRJP
1/2 HP 230VAC

I know how to replace it... I just want to make sure 1) it's the motor 2) The correct replacement model.

I found the Evergreens on Amazon... but I am just not sure.

Please help! Thanks!

Forrest

Does it spin freely by hand with power off? Is there a start/run capacitor?

I does freely spin by hand. I can't see a capacitor anywhere. I don't think there is because the wires go from the electrical panel inside the unit straight to the motor...

Is this a furnace/air handler/condenser unit? What's the make and model of the equipment?

That's an X13 ECM motor. Three phase electronically controlled. Those motors are around $750.

You may want to review this service bulletin and see if this could be an extended warranty repair:

Seems like it would work, but there's not really enough info at amazon site to be sure. HP and voltage is correct. You should be able to judge mounting and shaft size/length. The other major question is speed. Don't have info on what speed your current motor is set to run at, nor the range of the new motor, but chances are you should be able to get it close. Here is some info on your air handler: http://www.uniclima.net/pdf/fb4cnf_04pd.pdf

ok.... geez

I came home today after having the system off all day and turned it on and it works...

So at best the blower starts sometimes... I am sure it will cut off.... freeze up again because the blower didn't kick on.... This is what has happen a few times this week.

Again... All my voltages are correct going to my fan... even when it won't start. When it doesn't start and it freezes up... the fan spins like 3 times... stops spins 3 times again and stops... It does this over and over... once I let everything unfreeze... it may start blowing or not.... I tried it for 2 hours yesterday and it would never blow... even after everything was completely unfrozen.

Before I order a blower motor, I just wanted to ask one more time.

Is my thinking right... that it's the blower motor that is bad?

Thanks,

If the voltages to the motor are correct, and the blower spins by hand and isn't mechanically jammed somehow, then the motor or it's internal controller is bad.

Geez.... This is killing me.

It's not the blower fan.

The blower turns for 5 to 10 rotations... then stops... then repeats...

I check 110 and 25 VDC and everything is good... checked with 2 motors.

If I get 100 VAC on 2 post.... and I get 25 VAC on the low voltage post... The thing should work... Nothing else matters in the system. Is my thinking correct here?

Also, switched out the thermostat with the one up stairs... That wasn't it either.

How can this be?

Hi fgarvin,

What was ever done to correct your issue as I'm having the same problem with my X13 motor. It will spin and stop for every 5 seconds. Eventually mine did start up. Did you just replace yours ?
