Sale price$25.99 Regular price$35


These aftermarket replacements for the two 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). See the troubleshooting section of the MiniMax® Service Manual.
