Frequently Asked Questions (FAQs)
1. What is a thermal limiter switch?
Also known as the fan limit switch or simply the limit switch, it has two functions in the furnace's operation: It turns the fan on and off during the normal heating cycles of the furnace, and it senses heat and shuts down the furnace if the interior temperature gets too high.
2. Should a limit switch be open or closed?
The fan limit switch should be open when the furnace is off and full of cool air, so you should get an OL reading; if not, there's a short, and the switch should be replaced. The high limit switch should be closed when the furnace is cold, so you should get a zero reading; if you get the opposite, replace the switch.
