Topics I've Started

Armstrong SX-80 Squirrel Cage

13 February 2013 - 02:33 PM

I got a wierd one....someone may have seen this before.


I checked out this furance everything worked fine but when the main blower turned on a real bad noise came from the squirrel cage like it was hitting the sides. Opened it up and found that the squirrel cage moving back and forth, telling me the bearings on the motor had gone out. The squirrel cage was wobbling enough vibrating like crazy making it sound like it was about to blow out the back. So I proceeded to replace the motor, making sure to inspect the squirrel cage for damage, cracks, run out, bent, dirt build up etc.... I found the wheel to be in good shape so i centered everything up, put it back into the furnace cranked it up and wallla everything was blowing again, no noise, no significant noticable vibration. Keep in mind, during inspection I made sure that all the "weights" were still in place none appeared to be missing nor were in the bottom of the volute, I also cleaned of any significant dirt. 


I get a call 2 weeks later and they say they just heard a vibration that hadnt been there before. Opening the furnace and running the blower it starts out smooth but when it gets up to full speed the slight vibration is amplified through the duct work. So I take it out of the furnace all together and run it by itself with the wheel on it, still feeling a small vibration. So I proceed to remove the squirrel wheel and run the motor by itself and I still feel a slight vibration....hmmmm. Is the wheel bad and its taking out the bearings in the motor? Did i get a defective motor? Kind of scratching my head.  My instinct tells me to change motor and squirrel cage both.... anyone run into this before?

Armstrong SX 80 Blower Issue

28 January 2013 - 01:13 PM

I am trying to fix a furnace for my neighbor, problem seems very obvious but hit a couple bumps.


Armstrong Ultra SX-80- (Vintage 1996)


Let me explain- Furnace calls for heat, system goes on triggers the exhaust fan, igniter lights, flames come on 30 seconds later the blower is suppose to turn on but does not turn on until the high limit triggers. He has been running the system for the last 2 years with the system in "FAN ON" mode instead of auto.


With all that said my attempt to repair was to replace the main board and since the blower motor was making noise and going bad I replaced that too. Installed all that plus a new 24v transformer. Put the system in Auto, call for heat, same thing, exhaust fan turns on igniter on, fires, hits high limit, flames go out then blower goes on. What am I missing here....


To add to the clues, I was told the gas valve was changed out for some reason a few years back but I could not identify if the existing valve was the exact replacement or not. Is there a possibilty that the gas valve controls the blower on after it calls for heat? The gas valve appears to be functioning properly but I am thinking it may not be the exact replacement losing that function.


Any insite on this?  

Water Heater

Why is it when I come down stairs everyday, there is a little bit of water in the catch can at the bottom of the relief valve tube? Is that normal? Do I replace it?

AC Compressor wont kick on

30 August 2010 - 12:17 PM

I went upstairs last night to a nice warm room. I checked the air and I see the compressor is not kicking on (8 years old) I have yet to check, but from what i understand if you ohm out the cap and it reads zero the cap is dead. When I turn on the air the contactor pulls in and the fan turns on in the furnace and on the compressor outside. What can i check on the compressor to determine if it is good?


Up until last night, this unit has worked flawless.
