nordyne 80+ furnace

[danbon1]

I have a question, can a 3 year old furnace have a bad blower motor? the diognostic light on my furnace is blinking once and the legend says thats a limit switch open or load on w. (a tech wants to put in a motor)

[coolwhip]

Does the blower operate? or does the furnace cycle off on limit?

In addition, those furnaces have an 8 year parts warranty and up to a 250.00 dollar labor allowance. As long as the trouble was not caused by an air restriction.

it cycles off and no air comes from the vents.

it cyles off & no air comes from the vents.

Could be a bad motor or relay. Its hard to tell from here though. When was the last time you changed the filter in those three years?

[danbon1]

in november, are you sure about the labor allowance

[airhead1164]

I would check the voltage at the output on the control board, if that checks out I would ohm the motor windings. It could be a bad cap to, that should be tested also. Sounds like you have a parts changer to me. Good luck,

depends alot on size of duct too......that mod# is off a little....it should say tonnage of blower and btu....

[mo-flo]

i would inspect the a-coil and inside of duct too.....tell him you want to know what the static pressure readings are...ask him to try and figure out why it failed.

[mo-flo]

and these blowers aren't bad to replace.......i like em cause you don't have to remove control board,t-former,etc.

"are you sure about the labor allowance"

Labor allowance is for the quality pledge.Which is for heat exchanger or compressor failure in the first five years.Blower motors don't apply.If it is the motor you should NOT be charged for the part.

[Toolpusher]

On the t-stat, switch the fan from auto to On,
If the motor runs then it's probably the control brd.

If it doesn't then it could be the capacitor or motor.
not every filter needs changed every month.
Depends on the living habits of the h/o'er.

But I have also seen the ones that once a month wasn't enough. I'm sure alot of you have seen those places.
