I got a 50 gal, Natural Gas Water Heater, 9 1/2 years old.
Yesterday afternoon, my better half pointed out that we had no hot water. After litttle internet surfing, I learned that the Thermocoupler needed to be replaced. I replaced it and after several tries got the burning cooking. Hot showers for all!
About an hour ago, no hot water, pilot light was out again. Got it and the burner re-lit with no problem. Any ideas on what the issue might be now???
Not ready to replace the unit. My stimulus check hasn't arrived.
