TLDR

On your eikon® e2s unit, error E116: Heater Failed (E092) indicates a critical issue where the oven's primary heating element is not drawing sufficient current. This typically points to a faulty heating element, a failed Solid State Relay (SSR) controlling the heater, or a break in the associated wiring. Immediate inspection and component testing are required to restore heating functionality.

Technical Details

Repair Steps:

  1. Safety First: Power Disconnection. Before any inspection or repair, always disconnect the MERRYCHEF eikon® e2s from all power sources at the main breaker. This is crucial for preventing electrical shock and injury.
  2. Visual Inspection of Heating Circuit. Carefully open the oven’s casing to access the heating elements, their associated wiring, and the Solid State Relay (SSR) that controls them. Look for any signs of visible damage such as burnt wiring, loose connections, or physical damage to the heating elements themselves. Pay close attention to terminal blocks.
  3. Test Heating Element for Continuity. Using a multimeter set to resistance (Ohms), disconnect the wires from the heating element terminals and measure the resistance across the element. A healthy element should show a specific resistance value (refer to your eikon® e2s service manual for the exact specification, typically 10-50 Ohms). An “OL” (open line/infinite resistance) reading indicates a failed, open-circuit heating element that needs replacement.
  4. Test Solid State Relay (SSR) Functionality. The SSR is the component that switches power to the heating element. With power still disconnected, check the continuity across the SSR’s load terminals. If the heating element tested good, then with the control voltage applied (professional only, exercise extreme caution if testing with power), the SSR should show continuity across the load. If it remains open or shows a short, the SSR is likely faulty.
  5. Inspect Wiring for Breaks or Shorts. Using your multimeter, perform continuity checks on all wiring runs from the control board to the SSR, and from the SSR to the heating element. Ensure there are no breaks in the conductors or unintended short circuits. Pay particular attention to high-temperature rated wiring.
  6. Verify Control Board Output (Advanced). If the element, SSR, and wiring appear intact, the issue could stem from the control board not sending the activation signal to the SSR. This requires advanced diagnostics, often involving checking voltage signals from the board, and should only be performed by a certified technician due to high voltage risks.
  7. Replace Faulty Components. Once the faulty component (e.g., heating element, SSR, or damaged wiring harness) is identified, replace it with a genuine MERRYCHEF eikon® e2s spare part. Ensure proper electrical connections and insulation are maintained.
  8. Reassembly and Recommissioning. Carefully reassemble the oven, ensuring all connections are secure and all covers are correctly fitted. Reconnect power and perform a recommissioning test to verify that the oven heats up correctly and the E116 error does not reappear. Monitor current draw to confirm it is within specification.

Common Questions:

Q: What specifically causes error E116 on my MERRYCHEF eikon® e2s?

A: Error E116, Heater Failed (E092), typically indicates that the primary heating element is not drawing its required current, often less than 1A. Common causes include a burned-out or open-circuit heating element, a faulty Solid State Relay (SSR) that supplies power to the heater, or damaged/loose wiring in the heating circuit.

Q: Can I continue to use my eikon® e2s oven if the E116 error code appears?

A: No, it is not recommended to operate your MERRYCHEF eikon® e2s with an E116 error. The oven’s primary heating function is compromised, meaning it will not reach cooking temperatures, and attempting to operate it could potentially lead to further damage or safety risks.

Q: How long does it take to fix a heater failure on a MERRYCHEF eikon® e2s?

A: Diagnosis and repair typically take 30 minutes to 2 hours, depending on the specific component that has failed and the technician’s experience. This timeframe does not include potential waiting periods if replacement parts need to be ordered.

When to call a technician

For this error, we recommend calling a certified technician. Do not continue operation or attempt repair yourself.
