To reset the high limit switch on a pool heater, first turn off the power to the heater for safety. Locate the high limit switch—usually a red button near the control panel or behind an access panel—and press it to reset. Restore power and check if the heater operates normally; if the switch trips again, consult a professional as there may be an underlying issue.
