Looking for suggestions on repairing my water heater. The pilot light won't stay lit. I've cleaned the air intake and checked the venting in the attic but it didn't correct the problem. It will relight and at the end of the heating cycle, the gas turning off is blowing it out. Sometimes it'll stay lit for a couple days or a couple cycles.
The thermocouple was replace about a year and a half ago. Any suggestions?
