I cannot get the pilot light to stay lit on my heater. It is a Ruud UCAA 600C. There is gas running to the pilot and it will stay lit as long as I keep the knob pushed down. As soon as I let it go, the pilot goes out. It says I can adjust the pilot but I do not have any literature on the heater so I am a little lost on that one.
Optional Information: Make : Ruud Model : ucaa 100c Already Tried: I have tried holding the pilot down for over 5 minutes overall and it will not stay lit.
You need to replace the Thermocouple. Here is a photo of a thermocouple.
