To test a furnace limit switch, you can use a multimeter to check for continuity. First, turn off the power to the furnace. Then, locate the limit switch and remove the wires connected to it. Set your multimeter to the continuity setting and touch the probes to the terminals on the switch. If the multimeter beeps or shows a reading of zero ohms, the switch is functioning properly. If there is no continuity, the switch may need to be replaced.
