TLDR

On your eikon® e2s unit, error E116: HEATER FAILED indicates the oven requested heating but detected insufficient current draw from the heater circuit. This typically points to an electrical integrity issue within the heating system. Focus on inspecting all connections, fuses, and the SRB board to quickly restore oven functionality.

Technical Details

Repair Steps:

  1. Safety First: Immediately power down the MERRYCHEF eikon® e2s unit and apply lockout/tagout procedures before commencing any electrical troubleshooting or component replacement.
  2. Inspect All Heater Circuit Connections: Systematically check every electrical connection point along the heater circuit. This includes connections from the incoming power supply, through the main filter, to the relevant fuse(s) (F1 or F3 & F4 for V2 ovens), the Solid State Relay Board (SRB), and finally, to the heating element terminals. Ensure all connections are clean, secure, and free from signs of overheating or corrosion.
  3. Verify Fuses: Carefully test the continuity of fuse F1 (and F3 & F4 if applicable for a V2 oven) using a multimeter. A blown fuse indicates an overload or short circuit somewhere in the heater circuit that must be identified and corrected before replacing the fuse.
  4. Examine Heating Element Connections: Pay particular attention to the connections at the heating element itself. When tightening the front nut on the element terminals, always counter-hold the rear bolt to prevent twisting or damaging the element’s internal connections.
  5. Evaluate the Heating Element: While rare, measure the resistance of the heating element with a multimeter. An open circuit or extremely high resistance indicates a failed element. A typical element resistance for this model should be within manufacturer specifications.
  6. Inspect and Test SRB Board: If all connections are secure, fuses are good, and the heating element tests correctly, the issue likely resides with the Solid State Relay Board (SRB). Inspect the SRB for any visible signs of damage, burn marks, or bulging components. If no physical damage is evident, the board may still be faulty internally.
  7. Replace SRB Board (If Necessary): As a final step, if all other components and connections have been thoroughly checked and confirmed good, replace the SRB board. This board controls the power delivery to the heating element, and its failure would prevent proper current draw.
  8. Test and Monitor: After performing any repairs or replacements, restore power to the oven and initiate a heating cycle. Monitor the current draw on the heater circuit (if safely possible with appropriate equipment) to confirm it is operating within specifications (i.e., >1A).

Common Questions:

Q: What does E116: HEATER FAILED mean on my Merrychef eikon® e2s?

A: This error signifies that your oven tried to activate its heating elements but detected a very low (less than 1 amp) current draw, indicating a circuit interruption or component failure within the heating system.

Q: Where should I start troubleshooting an E116 error?

A: Begin by performing a thorough visual inspection of all electrical connections from the main power supply to the heating element itself, including the filter, relevant fuses (F1 or F3 & F4 for V2 ovens), and the SRB board.

Q: Is the heating element usually the cause of a Merrychef eikon® e2s E116 error?

A: No, the heating element itself rarely fails. The E116 error is far more commonly caused by loose, corroded, or damaged electrical connections, blown fuses, or a faulty Solid State Relay Board (SRB) that controls the element.
