To test the high limit switch in your appliance, you can use a multimeter to check for continuity. First, disconnect the power to the appliance. Then, locate the high limit switch and remove it from the appliance. Set your multimeter to the continuity setting and place the probes on the terminals of the switch. If the switch is working properly, the multimeter should show continuity. If there is no continuity, the switch may be faulty and need to be replaced.
