With a voltmeter and the color codes
you can isolate the problem to the 'stat or the furnace, with one reading.

If the problem turns out to be in the furnace, post the schematic, wiring and/or ladder diagram.

Evidently the problem lies elsewhere or there is more than one problem.

A temporary fix for this involves the mixing together of 1 part rum and 3 parts Coca Cola. :D

The root problem may not be in the furnace after all, it could be a power quality problem causing a failure in the furnace.

In a properly designed and built unit all parts are equally likely to fail. If not, there may be a factory-published Technical Service Bulletin detailing the design defect and the recommended fix.

-Educated guess (you might get lucky) or
-Uneducated guess (may be costly and it still isn't fixed) or
-you take a reading, decide what it means on the spot and proceed from there (reduces uncertainty in deciding what the problem is), or
