Coleman York OEM 3500-3121 Auto Reset Limit Switch | L165-60F Furnace High Limit Safety Switch
Product Description
Protect your electric furnace from overheating with the Coleman York OEM 3500-3121 Auto Reset Limit Switch. This genuine OEM L165-60F high-limit safety switch is designed to monitor furnace temperatures and interrupt the electrical circuit when the temperature reaches 165°F, helping protect the heating elements and other critical furnace components from excessive heat. Once the furnace cools to approximately 105°F (60°F differential), the switch automatically resets, restoring normal operation.
Manufactured to Coleman and York OEM specifications, the 3500-3121 provides reliable over-temperature protection and is an ideal replacement for a worn or failed factory-installed limit switch. Installing a genuine OEM replacement helps maintain the original safety, performance, and reliability of your heating system.
