Heat cycle runs properly then at the end of the cycle, the blower turns off for 2 seconds, then back on for 2 seconds.  It does that 3 times total before turning off until the next run.  I have cleaned, then replaced the thermocouple hoping it would be that simple, but apparently something else is malfunctioning.  Please let me know if you have any ideas on what the issue could be.  Thank you.

not familiar with this mod. but most furnaces of this vintage had a fan control it turns on at a set temp and shuts off at a set temp, sounds like your fan is shutting off too soon and residual heat is turning fan back on. turn your cut out lower if it is adjustable

Thanks, Dale.  I'm going to try and get in there over the weekend.  It's due for a good cleaning as well.  I will post the results as soon as I can.
