Goodman Furnace Delay?
 
Recently, I've noticed that my Goodman gas furnace connected to a Honeywell VisionPro 8321U1006 programable thermostat will run for a while, shut off, then immediately start back up. This often occurs several times in a row.

Is this normal? Does the VisionPro have a programable delay? If this isn't normal operation, how do I fix it?

Thanks!

Problem is probably in the furnace, or its venting.

So, that means the furnace computer should indicate an error when put in diagnostics mode. correct?

It may or may not.. It could be T.stat but, not likely. You can eliminate the T.stat by jumping the R & W wires. If it's not T stat you will have to check other things such as Air flow. causing limit to shut down furnace .When was your return filter replaced ?
