Common 440R-W23219 failures

Failure patterns we regularly see on Guardmaster safety relay hardware like the 440R-W23219:

  • Output contacts welded or burned: relay will not reset or drop out
  • Input circuit fault from a wiring or device mismatch (cross-fault detection tripping)
  • Reset / monitoring circuit failure: relay will not reset with valid inputs
  • Power supply section failure: no power LED
  • Age-related drift and slow drop-out on older electromechanical relays

Repair or replace?

ReplaceSafety relays are replaced, not repaired. The Guardmaster is a certified device, and its rating depends on unmodified internals. Replace the 440R-W23219 when it will not reset or its outputs no longer close. We stock the 440R-W23219. Order by 5:00 PM Central for same-day shipping.
RepairWe do not repair the 440R-W23219; a repaired safety relay cannot carry the original certification. If the relay trips on a healthy circuit, the fault is usually in the input devices or wiring, which we can help you troubleshoot.
