I have an Endless Summer tall patio heater. I am looking for a replacement thermocouple. Cannot find one like the one I have anywhere. It has two wires, one attached to the top and one attached to the bottom. The top has threads and is anchored to a flange with a nut. I do not know what the model is or where to find the model number. It is about 5 or 6 years old. Can you help find this part?
