Nordyne 626615R Limit Switch
The Nordyne 626615R Limit Switch is a critical safety component designed for furnace repair and high-limit protection in HVAC systems. This OEM replacement part is engineered to monitor plenum temperatures and prevent heat exchanger failure by opening the circuit when internal temperatures reach 190 degrees Fahrenheit. As an auto-reset limit switch, it automatically closes at 150°F once temperatures return to safe operating levels, eliminating the need for manual intervention during standard operational cycles.
For contractors servicing Nordyne or Miller units, the 626615R is the direct furnace high limit switch replacement for the legacy 626615 and 626567 models. It features a robust 1/2" diameter sensing probe and a single-pole configuration for seamless integration. Utilizing a genuine Nordyne 190F limit switch ensures that your equipment maintains the precise safety thresholds required for forced-air furnace applications, safeguarding against restricted airflow and short-cycling issues commonly found in aging residential heating systems.
Key Benefits:- Precise Thermal Protection: Fixed 190°F opening point prevents overheating and potential damage to the heat exchanger.
- Automatic Reset Logic: Automatically closes at 150°F to resume normal operation once cooling is achieved.
- Drop-in Compatibility: Optimized as the official furnace parts replacement for model 626615.
- HVAC Industry Standard: Manufactured with industrial-grade materials for long-term performance in high-duty heating cycles.
What causes a furnace limit switch to trip repeatedly?
Repeated tripping is usually a symptom of restricted airflow. Technicians should inspect for a dirty air filter, blocked returns, or a failing blower motor before replacing the limit switch.
Can I use this to replace a different temperature-rated switch?
No. You must always match the OEM temperature rating. Installing a higher limit than the factory-specified 190°F can create a fire hazard and lead to structural failure of the furnace cabinet.
How do I know if my 626615R is faulty?
If the furnace blower runs continuously while the burners stay off, or if the unit short-cycles despite clear airflow, use a multimeter to check for continuity across the terminals when the system is cool.
