Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

Yes you can reset a rollout (see attached pic for typical). You push the small button between the 2 leads. If it clicks you have reset it. If it doesn't click it wasn't tripped. One location for this device is just outside the burner chamber.The model number you give is for the AC coil not the furnace.
