I have a westinghouse gas furnace (nordyne) 80+ afue 5 years old. We have had a power outage and subsequently lost power to a water pump plugged into an outlet on furnace. The pump is good. The outlet is good. The breaker is good. Is there a reset button on the unit and if so where is it located. The manual is not clear?

If the outlet tests good and provides voltage for the pump and the pump is good as you say then I have no idea what your problem is since you said all is OK.
If there is the proper voltage at the outlet and the pump does not work then the pump is probably bad. If there is no voltage at the pump outlet then you will have to trace the wiring back and see where the voltage problem is.

Maybe the transformer in your furnace went bad...
