display board runs on 24 volts. make sure the secondary side of the transformer is putting out 24 volts. if the control pad is getting proper voltage and it doesn't work, replace the control pad and board

sounds like you need a new control board did mice nest under it that happens frequently

not a good move you will void warranty

you might want to add a bypass to the heater and not let the full return water through it this is called temp rise to slow the water down so it gets hotter

SORRY YOU HEATER IS GONE THE HEAT EXCHANGER HAS ALEAK THIS IS DUE TO POOR WATER CHEMESTRY ,LOW PH, OR SOMEONE USING TABLETS ON THE SKIMMER THIS DAMAGE THE METALS ON THE HEATER

I am not sure if you have received an answer to the issue, or not, but just in case! An EO5 error code is an open stack flue sensor, or switch, There are two forms of the stack flue sensor, so you will need to know which one you have on the heater.

What this error code means is that the sensor "read" the flue temp to be over 500 degrees. Usually, it is just gone bad and reading the wrong temp.

e05 error code means shorted stack flu switch or sensor. oder heaters have the switch, newer heaters have the sensor. make sure you know which one you have before ordering a replacement.

thermister problem

Are any of the service lights on on the back-side of the board? There are 4 possible lights that can illuminate...if any are, I need to know which ones please. If not, there is more troubleshooting required. If you would like a copy of the owner's manual which covers all these steps in detail, please send me an email using the contact feature of our site at www.arrowpools.net and I'll reply with a copy of it.John

external operating system. heater is on remote control

its not an error code

You have a bad thermal regulator. It is located in the inlet/outlet header. It looks just like a car thermostat.

is the heater running ? did u raise the temperature higher that the existing water temperature in pool ? are u running the pool pump long enough to achieve the temperature that you want ? IF CHECK (OK) 1- check the internal flow valve control is located between the cold and hot water little black cap, check the condition ,make sure no calcium deposit build inside, 2-is the water temperature in the heater is the same as the pool temperature ? is the pump got full prime with no air ? is the filter is clean ? is this heater propane or natural gas ?

The wrong orifice was installed. Sta-Rite changed their blower configuration 3 years ago. Heaters older than that have a flat orifice that works with the older style blowers. Newer heaters are equipped with a tapered orifice. Mixing a flat with a new blower causes whistling. Mixing a tapered with an old blower causes whistling. Good luck!

Your heater will only come on when the pump is circulating. Check to see if your pump is on or off. I am sure you already know that if you have it set to heat to 84 it should get to that temperature and maintain it within two degrees. If it doesn't, then here must be a problem. Don't immediately blame heater. Check pump operation.

Replace the thermistor. The cost is around $44.00
