The furnace high limit switch is typically located near the heat exchanger or burner chamber of the furnace.
The furnace fan limit switch is typically located near the heat exchanger in a heating system.
There are two limit switches per axis. Each switch is located at both extremities and they prevent the axis to go beyond the limits.
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.
The furnace high limit switch may keep tripping due to overheating caused by restricted airflow, dirty filters, malfunctioning blower motor, or a faulty high limit switch itself. Regular maintenance and inspection can help prevent this issue.

A limit switch on a furnace is a safety device that monitors the temperature inside the furnace. If the temperature gets too high, the limit switch will shut off the furnace to prevent overheating and potential damage.
When a typical residential furnace or gas package unit "high limit switch" is found to be bad it is replaced with a new one-not repaired.
This is a switch designated to stop a peice of equipment before it does damage to itself or the surroundings.
The limit switch on a furnace is typically located near the heat exchanger or burner chamber. It is a safety device that monitors the temperature inside the furnace and shuts off the burner if it gets too hot.
Where the high limit is located. It varies from model, and the manufacturer, you may find it on the front panel and will be located above the burners. This can easily be traced back by following the wiring diagram, or the schematic.
