Overheating can cause the limit switch to fail. If this happens, the furnace will be shut off. If you can’t figure out the cause, you can try checking your thermostat. You can check if it’s set to AUTO or Manual. If the switch is not setting the temperature appropriately, it could be a problem elsewhere in the system.

If you’ve recently remodeled your home, you should also check for a tripped circuit breaker or a loose wire. If the wiring is loose, splice it with electrical tape to prevent future problems. Also, make sure the thermostat battery doesn’t run out – if it’s dead, it will lose its settings and revert to default mode. Finally, make sure the thermostat is level and firmly attached to the wall. Make sure there are no loose wires or abrasions.
Lastly, remember to replace the thermostat batteries if necessary. If you’re unsure of the status of your furnace’s fan switch, you can check the settings by turning it up or down a few degrees to see if it works correctly. If it doesn’t, check your thermostat’s circuit breaker in your home’s breaker panel. Often, a dead battery means the furnace is overworked or isn’t set properly.

Another problem with heating systems is a faulty ignition system. This can prevent the heat from getting into the house properly. Checking the ignition system is crucial, but don’t forget to check for any other issues. If your furnace has a malfunctioning ignition system, it can significantly reduce the amount of heat it can produce. If this happens, you may need to replace the igniter.
If the fan is turning off too early, you should also check the limit control dial. The dial should turn to FAN OFF when the system has finished its cycle. If it turns off before FAN OFF, the switch is defective. You can check the limit control to make sure that it has cooled down to the FAN OFF temperature. Otherwise, you may need to replace the limit switch sensor.

Inspecting the fan limit control of your heating system can help you avoid a lot of problems in the future. The switch is designed to limit the amount of heat that your furnace can produce by operating without heating the plenum. If you see a high limit control, the fan may be operating at the FAN HIGH LIMIT. A high limit control can also be dangerous, causing the heater to operate continuously.
