The Nordyne 01-0838 Sequencer is a critical control component designed for multi-stage electric heat applications

the switch operates with a fixed cut-in temperature of 140°F and a fixed cut-out temperature of 120°F

individual replacements should always be inspected for debris

serving as a diagnostic signal for potential airflow restrictions or secondary failures

Nordyne 626404R Limit Switch The Nordyne 01-0838 Sequencer isThe Nordyne 626404R is a critical OEM replacement part engineered for high limit safety in Intertherm, Miller, and Revolv gas and electric furnaces. As a 145F double pole limit switch, this component is designed to monitor internal plenum temperatures and interrupt both sides of the electrical circuit should the system exceed the 145 degree Fahrenheit threshold. This rollout limit switch features an automatic reset with a 40 degree differential,
