Nordyne 105144000R Relay

Nordyne 105144000R Relay

The Nordyne 105144000R Relay is a specialized Time Delay Relay engineered for heavy-duty application in Nordyne-manufactured HVAC units, including systems from Miller, Intertherm, and Frigidaire. Designed to prevent short cycling, this critical component manages the sequencing of compressors and blower motors to protect against excessive wear and electrical surges. Featuring a 24V AC coil and SPDT (Single Pole Double Throw) contacts, it provides reliable switching for high-current loads up to 30 Amps. The fixed or adjustable timing circuit ensures that internal pressures equalize before a restart, maintaining the operational integrity of the sealed system. Built as a direct OEM replacement part, this relay utilizes standard 0.25-inch quick-connect terminals for an efficient, drop-in installation that matches the original terminal logic and mounting footprint. This component is essential for technicians performing reactive maintenance on furnaces and air handlers where precise interlocking control and transient protection are required to restore system balance during the cooling or heating call sequence.

Key Benefits:
  • Short Cycle Prevention: Actively delays system restarts to safeguard HVAC compressors from mechanical stress.
  • OEM Precision: Guaranteed high-tolerance timing accuracy and compatible mounting for Nordyne HVAC systems.
  • Enhanced Durability: Robust terminal construction resists vibration and high-temperature environments common in attic or closet installs.
  • Service Efficiency: Simplifies troubleshooting by restoring predictable sequencing in complex control circuits.
Common Questions:
  • How do I confirm if my 105144000R relay is faulty? Use a multimeter to check for continuity across the contacts and verify that the 24V coil is receiving power; if the relay remains open under a call for cooling, the timing circuit or coil has likely failed.
  • Can this relay replace a standard SPDT relay? While it shares the same contact form, the time delay function is specific to this part number and is necessary for systems requiring a programmed pause before the blower or compressor energizes.
  • What causes these relays to chatter? Inconsistent 24V signals from the thermostat or a failing transformer often cause contact chatter, which can lead to premature pitted contacts.
