My Intex Model ECO20110-2 pump runs for 10 seconds then shuts off for 1 second then runs for 10 seconds, then shuts off for 1 second, etc. I read where the temperature sensor may be bad. I took the housing cover off for one minute and the pump ran fine. I put the housing cover back on and the pump is still running. I can't find a replacement temperature sensor online. What can I do?
