This indicator normally means that your water temperature in the pool heater exceeds the internal limit. The corrosion should not be causing this problem. Since the high temperatures can be dangerous, you will probably have to contact a pool professional to service the machine.

(natural gas) the heater comes on for 3-5 minutes and then shuts off, and won't work again for hours. this is a shred heater between the pool and hot tub, but never used for the pool.


Check your high limit switch inside of the heater. Usually when the high limit switch pops it will take about 4 to 6 hours for it to reset itself without you resetting the system.
