Nordyne 626339 Fan Control

The Nordyne 626339 Fan Control, rated at F110-25F, is a critical OEM replacement component designed for precision airflow management in Nordyne, Miller, and Intertherm furnaces. As a veterans in the field know, maintaining correct blower timing is essential for preventing heat exchanger fatigue and ensuring optimal static pressure. This furnace fan limit switch is engineered with a 110°F "on" set point and a 25°F differential, effectively managing the blower motor control sequence to maximize heat recovery from the plenum before the system cycles down. This specific model replaces legacy part number 626236 and is a standard T-O-D 60T12 configuration utilized frequently in mobile home HVAC repair applications, specifically within MS series oil furnaces and MB series gas units. Its compact footprint allows for straightforward integration into existing control stacks where space is at a premium.

• OEM Compatibility: Exact drop-in replacement for Nordyne 626339R and Intertherm 626236, ensuring factory-spec performance.
• Precise Thermal Calibration: Fixed F110-25F temperature range provides reliable fan-on and fan-off cycling for mobile home furnaces.
• Durable T-O-D Construction: Built on the 60T12 platform for industrial-grade reliability in high-cycle residential environments.
• System Efficiency: Optimizes blower run time to improve AFUE performance and prevent short-cycling of the heating element.

What are the temperature specs for the Nordyne 626339?
