Circulator pump not working, help...........

I have a Dunkirk boiler with a L8148A aquastat. Every year I shut down the boiler for a few months and burn wood to heat my home. This year I started the boiler back up and the circulator has no power to it. I connected a direct power line to the circulator and it runs. If I hook it back up to the aquastat, the boiler starts, burner comes on, but the I have no power going to the circulator from the aquastat. Could there be some other problem, or does the aquastat need to be replaced? The boiler and circulator ran fine before I shut it down. I checked for power at the two circulator aquastat terminals, there is no power there.

It sounds like it's time for a new aquastat.
