Danfoss 117U6016 Starting Relay

Danfoss 117U6016 Starting Relay

When you are troubleshooting a compressor that refuses to turn over or is cycling on the thermal overload, the Danfoss 117U6016 Starting Relay is a specialized electrical component designed to provide the high-torque surge required for HST (High Starting Torque) applications. As a veteran-grade compressor start relay, this current-operated relay is engineered specifically for fractional horsepower compressors typically found in commercial refrigeration units, wine coolers, and reach-in freezers. Unlike standard PTC devices, this mechanical start relay uses an internal electromagnetic coil and a weighted plunger to momentarily engage the start windings. If you hear the distinct clicking of the overload protector but the motor fails to wind up, the contacts in your existing 117U6016 relay may be pitted or the coil may have failed.

Built for durability and precise timing, the Danfoss 117U6016 ensures the start winding is dropped from the circuit the moment the compressor reaches running speed, preventing winding burnout. This heavy hammer type relay is a direct replacement for many Secop and Danfoss branded hermetic compressors and is compatible with systems ranging from 110V to 240V. Its robust housing and heavy-duty terminals are designed to stand up to the high-heat environment of a condensing unit housing, providing the compressor starting torque necessary for systems with capillary tubes or expansion valves where pressures may not be fully equalized at startup.

Key Benefits for the Contractor:
  • High Starting Torque (HST): Delivers the necessary electrical punch to start compressors under load or high head pressure.
  • Heavy-Duty Mechanical Contacts: Provides a more reliable alternative to solid-state PTC starters in demanding commercial environments.
  • Universal Compatibility: Fits a wide range of Danfoss and Secop compressors found in brands like Samsung, Kenmore, and Haier.
  • Simple Terminal Layout: Standardized push-on connectors allow for fast field replacement, minimizing equipment downtime.
Common Technician Questions:

How do I test the Danfoss 117U6016 for failure?
Using a multimeter set to ohms, check for continuity across the coil (Terminals M and the line input). To test the contacts, hold the relay in its upright operating position; the start contacts should be normally open. When flipped upside down, gravity should close the plunger, showing continuity across the start terminal.

Can I use this relay on a compressor with a start capacitor?
Yes, this current relay is designed to work in conjunction with start capacitors to further boost starting torque in high-differential pressure applications.

What are the symptoms of a bad starting relay?
The most common signs include a "click-clack" sound every few minutes, a compressor shell that is hot to the touch but not running, or blown fuses/tripped breakers immediately upon startup.
