Exclamation Water Heater Scare

I am sorry if I did not read the complete post thread (it was very elaborate) and missed anything.
I have a 50-gallon Bradford White water heater, model # MI5036EN10. This morning it took the water longer than usual to heat up, so I panicked and visually inspected it from my very-very low expertise level height. The pilot was on, and the flame started every time I raised the thermostat temperature. The water got hot and stayed hot later on, so I did not catch if there was a real problem.
1. I opened a drain valve, and the water was clean.
2. The flame was uniformly blue.
3. The relief valve or its like on top worked (when I pressed on it, the water drained down the pipe on the floor.
4. I had some stuff lying around the flue on top of the tank - I removed it.
Could this be the reason? Maybe the sensors detected that the fumes could not escape because of this stuff? But it was not in the flue but around it outside.
5. My heater is 10 years old.

* Do you think I may have a problem?
* Is it easy to replace TC?
* Where is it located?

Your help and advice is greatly appreciated in advance.

I responded to your question in the other thread but this is better.

If you had a thermocouple problem or any safety sensor problem with your water heater......it wouldn't heat at all. It doesn't sound like you have any real problems with your water heater.

One reason for extended heating time is the temperature of the incoming water. In the winter the temperature of the incoming water is a lot lower requiring longer heating times.

Also as your water heater gets older.....mineral buildup increases inside the unit also causing extended heating times.
