My furnace doesn't seem to start when the thermostat calls for it to

cycles...perhaps a week's worth but then won't start until I touch my
meter probes to the T-T terminals the next time.

Any thoughts would be appreciated.

Sure sounds like you should call whoever services it for you. I'm hoping
you know also that oil burners do need annual service/tuning.

Among other things. That's where I'd start.
