If the Pentair Mastertemp 400 is not turning on, you should first check to make sure that all power connections are properly connected and secure. If the connections are okay, then you should reset both the high limit switch (located near the heater) and motor control center (MCC). This can be done by unplugging each of them and plugging them back in.
If after resetting these components it still does not turn on, then you may need to replace either one or both of them depending on what type of error code is being displayed. Additionally, if no error codes are being displayed but it still won’t turn on, then there may be an issue with your pool‘s electrical system that needs to be addressed before attempting any further troubleshooting steps.
If your Pentair Mastertemp 400 is not turning on, you may be dealing with a faulty electrical connection or an issue with the heater itself. If the power supply cord has come loose, try plugging it in firmly to ensure a secure connection. In addition, check all wiring connections to make sure they are tight and free of corrosion or damage.
If that doesn’t solve the issue, then you may need to replace the heating element or thermostat control board inside the unit.
