OPTIMUM Heater Replacement Parts
Optimum Pool Technologies manufacturers high quality replacement parts for the most common pool heaters on the market today. When your heater needs a repair, fix it the OPTIMUM way!

Compatible Replacement for MiniMax / PowerMax High Limit Switch
The two Compatible Replacement for Pentair 071017 High Limit Switches are important switches in your MiniMax or PowerMax pool heaters, and are used to detect when your water temperature has exceeded a safe level (150°F) and immediately opens the heat exchanger outlet when that happens.
Your MiniMax heater will indicate when it is time to replace the High Limit Switch when the “SERVICE” LED is displayed. It also may be time to replace your MiniMax High Limit Switch if all 3 lights on the back of the control board are on and one or both of the switches shows an open circuit (given proper water flow through the heater).
