Thermocouple needs replacing

We've had this gas heater for about 10 years. It's a Teledyne Laars.
For three years straight, the pilot light goes out, and it's the thermocouple that needs to be replaced.
Is this normal? If not, does anyone know why it keeps breaking?

Perhaps 10% of the time frequent pilot outages are caused by failing thermocouples.

75% of the time or so the cause is a dirty pilot burner or pilot orifice.

Pilot burner flames should be blue and have a hard, sharp flame like a small blow torch.

If the flame is white tipped or soft with a tendency to blow around more like a candle flame, the pilot burner and orifice need to be cleaned.

SeattlePioneer, are you saying I'm one of those dense, airhead, homeowners, lol?
Really tho, I'm not, and it's definitely the thermocouple.
My husband just came back from the plumbing supply store and was talking to a couple of plumbers that were there, and they said they've been seeing this a lot lately, so as they were arguing about the why's, the owner came out and said, "this is the reason" and showed them the package that said 'MADE IN CHINA'. :HF2:
