Nordyne 626607 Limit Switch
The Nordyne 626607 Limit Switch is a critical safety component engineered for specific sequence control in residential gas furnaces and air handlers. This L205F-20 limit switch is designed to monitor internal heat exchanger temperatures, featuring a fixed temperature setting that opens the circuit at 205°F and automatically resets once the temperature drops 20°F. As a SPST (Single Pole Single Throw) normally closed switch, it ensures system integrity by interrupting the burner circuit during an over-temperature event. This OEM replacement part is compatible with various Intertherm, Miller, and Nordyne M1, M2, and M3 series units. Precise thermal protection and a reliable snap-action disc mechanism ensure long-term stability and accurate cycling. When troubleshooting a furnace that is tripping the limit switch or exhibiting short-cycling, verifying the 626607 furnace limit performance is essential for maintaining safe operating parameters and preventing premature heat exchanger fatigue.
Key Benefits for Technicians- Precise Thermal Calibration: Factory-set at 205°F to ensure immediate response to overheating conditions without drift.
- OEM Compatibility: Direct replacement for Nordyne 626607, eliminating the need for mounting bracket modifications in the field.
- Automatic Reset Logic: Features a 20°F differential, allowing the system to resume operation once safe temperatures are restored.
- Rugged Construction: Built to withstand the high-ambient conditions of the furnace plenum for extended service life.
What causes a Nordyne 626607 limit switch to trip repeatedly?
Frequent tripping is often caused by restricted airflow, such as a dirty 16x25x1 filter, blocked return vents, or a failing blower motor. Ensure the static pressure is within manufacturer specs before replacing the switch.
Can I use a higher temperature limit switch if this one keeps tripping?
No. Using a switch with a higher opening temperature than the L205F-20 rating compromises the safety of the heat exchanger and violates the appliance's UL listing. Always match the OEM temperature specifications.
Is the 626607 switch compatible with Intertherm mobile home furnaces?
Yes, this is a standard high-limit safety for many Intertherm and Miller M-series gas furnaces. Always cross-reference the part number on the existing switch's faceplate to confirm.
