My 6+ year-old water heater's pilot light won't stay lit. I held down the pilot light switch upwards of 5 minutes and it still extinguishes when I let go. The flame encompasses the last 2-3 mm of the thermocouple so it's positioned correctly. I put in a new thermocouple and same problem.
How likely is it that the new thermocouple is bad?
How likely is it that the control unit is bad? If the control unit is bad, should I just replace it or replace the whole water heater?
Thanks!
