Carrier 338096-704 Limit Switch
When you are troubleshooting a furnace that is short-cycling or hitting a high-limit trip, the Carrier 338096-704 Limit Switch is a critical OEM replacement part for restoring safe thermal regulation. This furnace limit switch is a normally closed (NC) safety component designed to monitor the heat exchanger temperature. It features an automatic reset function with a fixed open temperature of 160°F and a close temperature of 140°F (L160-20F). As a Factory Authorized Part, it ensures precise calibration for Carrier, Bryant, and Payne gas furnaces, maintaining the exact timing required for the blower motor circuit to engage or disengage. Using this genuine HVAC part prevents hazardous conditions like overheating or flame rollout, ensuring the HVAC system operates within its engineered parameters. Whether you are dealing with a faulty disc style limit switch or performing preventative maintenance on a high-efficiency furnace, this component provides the exact electrical compatibility and mechanical fit necessary for a professional-grade repair.
Key Benefits- Precise Thermal Calibration: Factory-set to open at 160°F and close at 140°F, preventing heat exchanger damage.
- Automatic Reset Logic: Eliminates the need for manual intervention once the system cools to safe operating temperatures.
- Cross-Brand Compatibility: Direct replacement part for a wide range of Carrier, Bryant, and Payne equipment.
- Durable Construction: Built to withstand the high-cycle demands of modern residential HVAC units.
What are the symptoms of a failing limit switch?
Technicians often see the blower motor running continuously or the furnace short cycling when the switch fails to maintain continuity or trips prematurely.
Is this switch compatible with my specific furnace model?
This 338096-704 switch is widely used across 59MN, 59TP, and 59SP series units. Always verify the L-rating on the original part before installation.
Can I use a universal limit switch instead of this OEM part?
While universal switches exist, using a genuine Carrier OEM component ensures the exact temperature differential required for the safety circuit's integrity.
