COMPRESSOR HUMS OR CLICKS BUT FAILS TO START

Supco Refrigerator Relay Overload Capacitor (3-in-1 hard-start relay, overload, and start-capacitor combination) URCO410, Fixes Compressor hums or clicks but fails to start

Supco solid-state hard-start relay kit for refrigeration systems. Includes a relay, overload, and start capacitor; rated 110–125 VAC (115 VAC nominal), 1/4 to 1/3 HP compressors, maximum continuous RLA 6.8 A, and 243–292 MFD capacitance. The manufacturer states it is for systems with or without run capacitors and works on RSIR, CSIR, PSC, and CSR compressors.

Common Symptoms

  • Repeated compressor clicking or buzzing during attempted startup
  • Compressor starts intermittently or shuts off shortly after starting
  • Refrigerator remains warm because the compressor cannot start
  • Overload protection trips during compressor startup
  • Low-voltage conditions make compressor startup unreliable

Check Before Replacing

  • Disconnect electrical power before inspecting the compressor start components.
  • Verify the compressor nameplate is within the kit’s 115 VAC, 1/4–1/3 HP, and maximum 6.8 A continuous RLA ratings.
  • Visually inspect the existing relay, overload, and capacitor for loose terminals, heat damage, bulging, or leakage without touching energized components.
  • Confirm that the compressor terminal markings and the kit wire designations correspond to Common, Start, and Run before installation.
  • After installation, restore power only after all covers and connections are secured, then observe whether the compressor starts normally; continued clicking or failure to start requires further appliance or compressor diagnosis.

Pro Tip

Match the kit to the compressor’s horsepower and continuous running amperage—not just the refrigerator model—and photograph the original wiring before disconnecting the old components.

Part Details

Part NumberURCO410
Part TypeRelay Overload Capacitor (3-in-1 hard-start relay, overload, and start-capacitor combination)
ManufacturerSupco
Appliance TypeRefrigerator
Primary FunctionProvides a high-torque start boost for a 115 VAC refrigeration compressor while combining the start relay, overload protection, and start capacitor in one solid-state kit. It is intended for 1/4–1/3 HP compressors and can be used with or without a run capacitor.

Installation Notes

  • Disconnect and isolate appliance power before working on the compressor electrical connections.
  • Install only when the compressor rating matches the URCO410 specifications.
  • Use the supplied wire designations and the appliance or compressor wiring diagram to identify Start, Common, and Run connections.
  • Ensure push-on terminals are fully seated and the kit is secured with its intended mounting clip so it is not left loose near vibrating components.
  • Replace the compressor terminal cover and any rear access cover before returning the appliance to service.
  • If the compressor still fails to start after correct installation, do not assume the kit is the cause; further diagnosis of the compressor and appliance circuit is required.
