In Topic: Older Lennox airhandler, replaced blower motor but it keeps shutting off

13 June 2013 - 07:49 PM

Well, went to Grainger, got the part. Everything is working fine. Probably needs freon, though. Does not seem to be blowing that cold. What is freon going for these days? It is the R22 type. Wished it was the newer one. It is a Trane, installed in 2007.

I got the service manual from this site, Thanks so much, and did the test mode. Link to download service manual, if anybody felt froggy. http://appliantology...service-manual/


There are four steps, first starts it, second closes the damper, third shuts off compressor, closes damper and force starts the defrost. Steps one and two went off without a hitch. Third, the compressor and damper closed like it was supposed to, don't know if the heater was working, still trying to see where to check that at, but the display was supposed to show 33 33, but it did not. It showed the regular display. pushed button again, it made the display go like it was supposed to in step no. 1. and compressor stayed off like it was supposed to, there is a seven minute delay.


Does that further confirm that the board is bad?

AO Smith DL1056

  • HP: 1/2
  • V: 115
  • Amps: 6.5


When I ordered the part, the home depot AO Smith part, it said it was the 208-230v, which is obviously incorrect, according to your link above and other ones on the net. That is the first thing I checked. Well there you go. Hopefully after taking this one back and getting the correct one, I will make sure it is the correct voltage, I will get the new part from Grainger, my A/C will work correctly and not shut down. Thanks all, I will update when exchanged.

What voltage does the air handler operate on? 120? 240?
What voltage is the old motor?
What voltage is the new motor?
Microfarad )mfd) on the capacitors?
What volt rating for motor capacitors? 370....440?

Correct blower wheel rotation?

What is fan voltage OUT of the relay board?

It is 240

Voltage for both is the 208-230

10 MFD 370

yes, correct blower wheel rotation because when it was on, it was blowing real hard in the house.

The last question, are you asking about the voltage out of the blower relay?



sounds like

the "old" Motor was 220v

and "new" Motor is 120v  :whistling:


old Motor part number ?

new Motor part number ?

Both motors are 208-230.

Old part Emerson K55HXTGB-8797

New part AO Smith DL1056


Like I said before, they were exactly the same except for amperage.



Should I return the home depot part and get the correct amped one? There is a Grainger store nearby, they have one there.


Thanks again for your advice. I don't know when the last motor was "fried". The last owner bought the property in 2010 and moved out april 2012, so this house has been empty since then.

Fan motor is working when first turning on and works for several hours afterwards. Then it shuts off, then the error. The motor is turning freely. So I think it is a bad control board. Is that the same as the controller? Thanks for the help by the way.
