    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.

    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?

    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,

    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.
