Question about Heating & Cooling
I can turn the power off at the furnace and then restart it and it will run a cycle again.... but if i don't go up and turn the power off from the furnace it will not turn the burners back on for another heat cycle.. i have been told it is the limit switch and i would like to know how it should test if it is good with a volt ohm meter.. when it is cool it still reads closed... does that mean it needs replaced?

Probably need to replace the limit. Pull the wires off of the limit and set your meter to ohms. If it beeps while holding one test lead on each of the connectors on the limit itself then it should be good. If no beep it may be stuck, still too hot, or bad part. Try to give it a whack with something solid like the end of a screwdriver sometimes this will release a stuck limit. If you get it to fire up and heat again make sure your blower comes on and your filter is cleaned. You need to check the temperature rise on your furnace afterwards. Limits dont trip for no reason usually.
