Merrychef e1s - Error E 106: Cavity Reaches 300°C After Setpoint Control Exceeded

🛑 Critical / Stop Operation
Warning: The information provided here is for educational purposes only. Working with commercial kitchen equipment involves high voltage, gas, and high temperatures.

TLDR

On your eikon e1s unit, Error E 106 indicates the cavity temperature has exceeded 300°C, suggesting an overheating condition or potential fire hazard. This is often caused by a malfunctioning or obstructed convection fan. Immediately power cycle the unit and inspect the cavity for obstructions and verify the convection fan's operation.

Technical Details

Repair Steps:

  1. Perform a Safety Check and Power Cycle: Immediately power off the unit and disconnect it from the power supply. Allow the oven to cool completely. Carefully inspect the cooking cavity for any signs of fire, excessive grease build-up, food debris, or obstructions that could restrict airflow or ignite.
  2. Inspect the Convection Fan Assembly:
    • Access the convection fan motor and impeller. Depending on the eikon e1s model, this may involve removing the rear or side panels.
    • Manually spin the convection fan impeller. It should rotate smoothly and freely without any binding, grinding, or excessive wobble.
    • Check for a loose, damaged, or missing impeller on the motor shaft. A loose impeller will not move air efficiently, leading to hot spots and overheating.
    • Inspect the wiring connections to the convection fan motor for any signs of looseness, corrosion, or burnt terminals.
    • If the impeller appears intact and spins freely, use a multimeter to check the convection fan motor’s windings for continuity and resistance (refer to the service manual for expected values). Consider temporarily testing the motor with an external power source (if safe and appropriate for your skill level) to ensure it operates correctly.
  3. Verify Cavity Temperature Sensor:
    • Locate the cavity temperature sensor. Inspect its wiring for any damage or loose connections.
    • Using a multimeter, measure the sensor’s resistance (if an NTC thermistor) or voltage output (if a thermocouple) at ambient temperature. Compare the readings to the manufacturer’s specifications in the service manual. A faulty sensor can provide inaccurate readings, causing the control system to mismanage heating.
  4. Examine Heating Element Control (Advanced):
    • If the convection fan and temperature sensor appear functional, the issue might lie with the component controlling the heating elements, typically a Solid State Relay (SSR) or contactor. A “stuck-on” SSR can cause continuous heating regardless of the setpoint.
    • This step requires advanced electrical diagnostic skills and should only be performed by a qualified technician.
  5. Assess the Control PCB:
    • If all preceding checks yield no definitive fault, the Control PCB (Printed Circuit Board) may be at fault. This could involve an internal component failure preventing proper fan control, heating element regulation, or misinterpretation of sensor data.
    • Replacement of the Control PCB is a last resort and should be performed by a certified technician.
  6. Reset and Test: After addressing any identified issues, reassemble the unit, restore power, and monitor the oven’s temperature control closely during a test cycle to ensure the E 106 error does not recur.

Common Questions:

Q: What does the E 106 error code mean on my Merrychef eikon e1s?

A: Error E 106 indicates that your Merrychef eikon e1s cavity temperature has exceeded 300°C, even after attempting to control at the setpoint. This is a critical overheating condition, potentially due to airflow issues or faulty heating control.

Q: Is it safe to operate my eikon e1s with an E 106 error?

A: No, it is not safe to operate the unit with an E 106 error. Exceeding 300°C can pose a fire hazard and lead to significant damage to the appliance. The error signifies a critical safety and operational fault that must be addressed immediately.

Q: What are the most common causes for a Merrychef eikon e1s to display error E 106?

A: The most common causes for an E 106 error include a failed or obstructed convection fan, a loose or missing fan impeller, or internal cavity fires due to excessive grease accumulation. Less commonly, a faulty cavity temperature sensor or a problem with the heating element control circuitry could be responsible.

When to call a technician

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

  • Equipment shows a critical or stop-operation fault.
  • You smell gas, burning, or see smoke or sparks.
  • Error returns after following the steps above.
  • You are not trained to work on this equipment.
  • Warranty or safety could be affected by DIY repair.
