Nordyne 626403R Limit Switch
The Nordyne 626403R is a high-precision 140F CO Auto Limit Switch designed for critical safety monitoring in Nordyne, Intertherm, and Miller electric furnaces. As a veteran-grade OEM furnace limit switch, this double-pole (2-pole) component acts as a primary fail-safe, monitoring discharge temperatures to prevent heat exchanger damage. This unit is the direct replacement for 626260 and also supersedes legacy part numbers 626403 and 6264030, ensuring a plug-and-play installation for HVAC technicians servicing mobile home or residential electric heating units. Engineered with a durable bi-metal sensor and a 3/4" diameter (64TX11) footprint, the Nordyne 626403R provides an automatic reset function that restores operation once temperatures drop below the 140-degree threshold. For contractors, using this HVAC rollout limit switch ensures compatibility with FEHA, FEHB, and SEHA series units, maintaining the original equipment’s efficiency and safety specifications.
Key Benefits for HVAC Professionals- Universal double-pole configuration allows for simultaneous control of two heating elements or safety circuits.
- Standardized L140F temperature rating provides consistent thermal protection for Intertherm/Miller furnaces.
- Direct technical upgrade for the retired 6262600 and 626260 models, eliminating mounting modifications.
- Reliable automatic reset mechanism reduces unnecessary service calls by clearing faults once parameters are safe.
- Compact, OEM-spec construction ensures a perfect fit in tight plenum or rollout assemblies.
Is the 626403R compatible with single-pole 140F applications?
While this is a double-pole limit switch, it can often replace single-pole equivalents like the 626259R in specific wiring configurations, though using the exact pole match is recommended for safety circuit integrity.
What causes a 140F furnace limit switch to trip frequently?
Frequent tripping usually indicates restricted airflow, often due to a clogged air filter, blocked return vents, or a failing blower motor, rather than a faulty thermal limit switch.
Does this switch require manual resetting?
No, the 626403R is an auto-reset limit switch. It will automatically close the circuit once the sensed temperature falls approximately 40°F below the 140°F trip point.
