Heater turns off quickly with "Rollout sw open" error. Also "flame noise" is too much?

[PashkaTLT]

Hello,

My heater is Raypac R407A. I have the following issues:
1. It turns off quickly (1-15 minutes after turning on), with "Rollout sw open" error. And I have to manually reset the switch inside to start it again.
2. Sometimes (rarely) the error is Fan lockout" or something like that. When I take the panel off I don't see any obstruction to the fan.
3. I feel like the heater is working too loudly like the flames are too powerful and not consistent. Please see this video: VID_20220530_164647.mp4

Thank you in advance.
Kind regards,
Pavel

Unfortunately, that heater is at end of life. If you look at all that rust on the panel you can see where the flame has been outside the combustion chamber. That rust is not from just water.
Your heat exchanger has been leaking and has corroded the burners and bottom of the heater. There is debris on the burners. That is what is causing the rollout switch to trip, along with steam from the leak.
In the picture of the exchanger you can see that the insulating material is deteriorated. That's what is sitting on the burners.
Your gas valve is corroded from water and should not be in service, they can stick open and the heater not turn off. The blower is severely rusted. Not likely the heater could be repaired if you were willing to spend the money it would take.

Thank you. I'm willing to try to reanimate it and use it until it dies completely.
I took the heat exchanger off, cleaned it up with a pressure washer and cleaned everything I could reach in a heater with a pressure washer.
See the 4 pictures below of how it looked after cleaning.
I cleaned the burners and the orifices with brushes & toothpicks without taking them out.
After I assembled everything back, the heater doesn't start working well, says "Main ign failure". Here's the video:

Should I take out the burners/orifices and clean them out properly? Can I do this without taking off the heat exchanger first?

Read above again.

This $10 part fixed the problem for me. https://www.amazon.com/gp/product/B004VTGKJQ/ref=ppx_yo_dt_b_asin_title_o03_s01?ie=UTF8&psc=1

Besides all the problems mentioned above, you have small to "GAPING" holes in several of your burners!!! Note the LARGE hole in the burner next to the bottom burner in your "cleaned" photo . This is not a DIY project for someone without experience in servicing gas heaters in order to make them operate safely/correctly and the cost to correct the problems may approach the cost of a new heater.

Turns out it is a DIY project for someone without experience in servicing gas heaters
I replaced the pilot:

And voila! The heater is working silently & well now and I'm enjoying my 90 degrees water!
