The heating element is not working properly . The element can get coated with certain minerals .You need to clean the heating element with a brush.

Max e therm heater makes loud noise at start up and does not stay on? What could it be?

Water flow might be the issue. Check the Thermal Reg or any other external by-pass.

I have a starite propane heater i turn it on it calls for heat it will start heating then a couple minutes later the filtration lines and heater give a loud banging noise and service heater light comes on...

This is either one of two thing.
Either you pump is clogged, or failing and not providing adequate flow, or the heat exchanger has a hole in it. I would hope that it is just a flow issue as the exchangers are very expensive.
Check the pump first, and also make sure there is no leaking water from the heater

When power to heater turned on r3 is displayed

Sounds like low water flow. Is there a manual bypass that may be open? If not, thermal regulator may be bad, or worst case scenario, heat exchanger is blocked due to imbalance of ph/alkalinity in pool water. Good luck.

Sta-rite gas heater won't ignite

I am not sure if either of these issues have been solved, but with the AGS light on, you will need to check the flow of water first. If it is below what is needed for the heater, this will light up. If the water flow is fine, then check the water temp on the display panel. If it is readin higher than that of the ACTUAL pool water temp, you need to replace the Thermister.

If the water temp displayed is about that of the pool water, then the Automatic Gas Shutoff will be the next thing to check and replace.

You can tell IF a Sta-Rite heater has been converted by the model number. The Convesion Kit is supposed to come with a sticker stating that the heater has been converted, but there are two options for the kit and the one without the sticker is cheaper.

If you take off the top two halves of the heater, on the Junction Box there should be a Tri-fold card there. Unfold it, if the model number ends with NA it is a Natural Gas Heater, LP would be Propane.

AGS code

AGS switch wiring may be bad. Jumper the switch at the molex connector on the board using a paper clip, with the plug still plugged on. Restore power.
