Marvel Bar Refrigerator Error Code Ed: Defrost Sensor
Ed on a Marvel ML15BCG2**, ML15BCF3** or ML15BCP3** beverage center means the control found an open or shorted circuit on the defrost sensor. The manual says to unplug the power cord immediately and call service to have the defrost sensor replaced. Without proper defrosting, heavy frost can build up.
High: the manual directs you to unplug the unit at once because defrosting is not working.

What does Marvel error code Ed mean?
Cooling coils collect frost, and the control runs a defrost cycle to clear it. A defrost sensor tells the control when the coil has warmed enough to stop. The control also checks that sensor's circuit. If the circuit is open, with a broken path, or shorted, with the leads touching, the control cannot defrost correctly, and it shows Ed on the 7-segment display. The manual states the cause as an open or shorted circuit condition on the defrost temperature sensor. It adds that the unit then does not defrost properly, which can build up heavy frost and cause water damage to the unit and the surrounding floor. That is why its instruction is stronger than for the compartment sensor code: unplug the power cord immediately and call service to have the defrost sensor replaced. The warning is about water that melts later and spills, not about an immediate electrical hazard.
Affected models and control systems
This applies to the Marvel ML15BCG2**, ML15BCF3** and ML15BCP3** beverage center with the electronic control, per the installation, operation and maintenance instructions 41014803-EN Rev A.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- Ed on the temperature display
- Frost building up on the back wall or coil area
- Water on the floor under or around the unit
Possible causes
Listed in Marvel's documentation
- Open or shorted circuit condition on the defrost temperature sensor
Other likely causes — what usually sits behind error code Ed on this control. A technician confirms which one it is before any part is replaced.
- Defrost sensor lead broken near the evaporator
- Moisture or ice at the sensor connector
- Sensor body failed after many defrost cycles
- Control input for the defrost sensor not reading
Safe checks before calling for service
- Unplug the power cord, as the manual says, and take the drinks out.
- Put towels on the floor in front of the unit, because ice can melt and run out.
- Leave the door ajar so the cabinet can thaw and dry out.
- Call service, giving the code Ed and noting any frost or water you see.
How a technician diagnoses error code Ed
- Confirm Ed and look for frost build-up.
- Allow the unit to thaw fully and dry.
- Inspect the defrost sensor connector and lead.
- Measure sensor resistance to confirm open or short.
- Replace the defrost sensor, as the manual directs.
- Restore power and watch a full defrost cycle.
- The sensor sits on the evaporator behind the liner, so reaching it means taking parts out.
- Water from heavy frost can reach electrical parts if the unit is left running.
- Verifying a defrost cycle needs timed observation.
How error code Ed differs from similar codes
Ed is the defrost sensor code, while EL is the compartment temperature sensor code on the same control.

Why does the manual say to unplug it immediately?
Without defrosting, heavy frost can build up and cause water damage to the unit and the floor.
Is Ed the same as EL?
No. EL is the compartment sensor. Ed is the defrost sensor.
Can I keep the drinks inside?
Move them elsewhere, since you will be unplugging the unit.
