If a fan limit switch is bad, the furnace will not shut off, leading to overheating, smoke, and a possible fire.

The first sign of trouble is when the furnace won’t turn off. The next time you go to turn it on, it should pop right off with a click. You have a problem with your fan limit switch if it doesn’t.

The fan limit switch is a safety device installed in the furnace, which will turn the furnace off when there’s an overheating condition. This can be caused by a short circuit, a bad thermostat setting, or the pilot being out.

In many large industrial buildings or systems, it can be necessary to use a fan limit switch.

The fan limit switch is typically used when the air volume going through the ventilation system needs to be controlled.

When set correctly, the fan limit switch will help reduce energy costs by keeping the airflow at an optimal level.

This is usually set by monitoring the temperature of the room, and when it reaches a certain threshold, then the fan will activate.
