I have a 50 gallon Kenmore gas water heater (model # 153.330551) . The pilot light keeps going out intermittently.
I replaced the thermo couple (standard Home Depot Honeywell replacement) but to no avail. The new thermo couple did make lighting the pilot light more reliable. But the pilot light still goes out every now and then. I think it happens after the burner is turned off.
Any other suggestions?

When you put the new T/C in did you clean the pilot venturi good ? The T/C get red from the pilot ? The burner clean ? burn good?

When I replaced the TC, the only area I cleaned was the pile of ashes sitting on top of the burner( all three parts come out together) . The pitot flame is about an inch long. The top 1.4 inch of the TC is red hot. The burner, which looked pretty clean when I had it out, puts out a strong blue flame.

Pilot has not gone out for 24 hours. Maybe the new TC did the trick.
