International Comfort Products Furnace Limit Switch

The International Comfort Products Furnace Limit Switch is a replacement high-limit safety switch (also called a furnace limit control or thermal limit switch) for gas furnaces. It monitors temperature inside the furnace heat exchanger and plenum area. If temperatures rise above a safe level, it shuts off the burner to protect the furnace and your home.

Key Features:

• Temperature-activated safety control that interrupts the burner circuit when overheating is detected
• Helps protect the heat exchanger and other furnace components from heat damage
• Automatically resets once the furnace cools, in line with the design of the original control
• Offered in several temperature ratings and configurations, so you can match the control to your furnace
• Replacement part for International Comfort Products furnaces

A working limit switch is an important part of safe furnace operation. A failed or faulty one can cause nuisance shutdowns, short cycling, or a furnace that won't ignite. Select the variant with the part number that matches your original control. Disconnect power before servicing, and have the work done by a qualified HVAC technician.
