Thermocouples are all the same. The only difference is the length. They commonly come as short as 12 inches and as long as 42 inches. What determines the size is the distance from the pilot safety to the pilot light. If it will reach, it will work. Most hardware stores carry them. You don't need a photo.

Pilot sensors on the other hand can vary widly. A thermocouple is for a standing pilot, the pilot sensor is for spark ignition. One problem common to a sensor is carbon build up. Gently clean the sensor with emery cloth and reposition it. GENTLY tapping on a pilot, while the pilot is lit will also help clean it. When doing so, the goal is a crisp blue flame. If the sensor doesn't sense the flame, it will not allow the main gas valve to open. This is good! it is doing what it is designed to do.

The Payne/Day Night brand is a United Technologies product and is excactly the same as a Bryant or Carrier product. They are built in the same factory, using the same parts. The only difference is the name tag.

Hope this helps.
