To test a limit switch on a furnace, you can use a multimeter to check for continuity. First, turn off the power to the furnace. Then, disconnect the wires from the limit switch and set your multimeter to the continuity setting. Touch one probe to each terminal on the switch. If the multimeter beeps or shows a reading of zero ohms, the switch is working properly. If there is no beep or a high resistance reading, the switch may be faulty and needs to be replaced.
