How to replace swimming pool heater core

I assume you are referring to the heat exchanger. Usually when these fail the heater is replaced. Reason being that this is the biggest money part of the unit. The part alone will run pretty deep into the price of a new heater.
Then you still have the old burner tray, old gas valve, old thermostat and old internal ignition device. Each of these components run several hundred dollars apiece. It doesn't make sense to throw good money after bad.
If this exchager was leaking from a salt water pool (common these days) it would be advisable to replace the heater with a Sta-Rite MaxiTherm with the cupro-nickle exchanger. This part is coiled which allows for better water flow and less corrosion than a standard copper exchanger.
To replace the exchanger is not all that tricky if you are handy with a screwdriver, wrenches and plumbing. If you have any doubts get a pro over. Remember you are literally playing with fire.

Sta rite maxetherm wont fire i have 240v in 24v

It sounds like you have started debugging this heater. In the manual located at on page 29, 30 and 31 there is a schematic that you may be able to follow to figure this out the rest of the way. If you get stuck I recommend you call the Sta Rite technicalsupport at 888-782-7483 and they might be able to help you figure this issueout. I hope this helps.

Please vote on this answer. Thank you.

Sta Rite SR400 NG heater with code r=5

You can find an Owner's Manual online at the following site:

IF you have tried to restart the heater and received the same outcome, the r5, or S, is a badk control board. Sorry about that one!

What you may want to try is resetting the heater. You will need to put the SunTouch in the maintenance mode. Then turn off the heater, turn off the Circuit Breaker for the heater, wait about 15 to 20 minutes, then reverse the order. Circuit breaker, then heater, then try and start the heater without the SunTouch first. If it works, then try with the SunTouch.

The sta-rite maxitherm heater I am asking about is for an inground pool

I would like you to try a reset of the system. Turn off the power on the heater, then turn off the circuit breaker that goes with the heater. Wait about 20 minutes and then try and start the heater. If it still will not power up, turn the display panel over, there are diagnostic lights on the back side. If the light is on next to the AFS, that is the Air Flow Switch.
