I have a small custom pool that was built in Sept 2014. We have the Pentair Mastertemp 400 heater. In December the heater quit working and the Pentair tech came out and said the Thermal Regulator was bad and they replaced it. Yesterday our heater stopped working again and the Pentair rep came back out today. He said the Thermal Regulator was bad again. Is this normal? Has anyone else had this issue? Any ideas of why this would keep happening?

Usual culprit is the pool water is not balanced correctly. Thus causing corrosion. Do you manage your pool chemicals?
We have a company that manages our chemicals but they were not watching the Salt Level which got very high. We drained the pool and started fresh. Now we are having issues with the Chlorine being too high. Our new pool service company said that our Salt generator is too big for our pool size. We have the IC40 and our pool is 3,800 gallons (very small). The pool service company shut the salt generator off about a month ago and the Chlorine levels are still high. Do you think we should have a smaller size salt generator like the IC15 or IC20?
You don't want to go too small as it can limit the live of the unit. You could get a smaller unit but you should be able to manage the amount of chlorine being generated. Do you have automation or just a regular system?
You can manage the amount of chlorine the system generates. If it's really producing too much, turn it off for a period of time.
