Fix:

• Test control voltage input with a multimeter to confirm proper signaling.

• If the SSR output does not respond consistently, replace it with a Custom Delis parts designed for your specific model.

Abnormal Noise or Clicking

Sign: While SSRs are designed to operate silently, some users report faint noises such as clicking, buzzing, or humming.

Cause: Noise usually indicates a fault in the internal semiconductor or control board. Sometimes, it can also signal a related wiring or grounding issue.

Fix:

• Check grounding connections to ensure electrical stability.

• Replace the noisy or defective SSR with the correct Custom Delis equipment part.

• If the issue persists, a technician should inspect the control board for deeper faults.

Intermittent Equipment Performance

Sign: The equipment works properly at times but occasionally malfunctions without a clear pattern.

Cause: A deteriorating SSR may perform inconsistently as internal components fail intermittently under load.

Fix:

• Document when the failures occur to help diagnose the issue.

• Test the SSR under different load conditions.

• Replace the part if inconsistencies are confirmed. Using genuine Custom Delis equipment parts ensures stable and predictable performance.
