Federal Display Refrigerator Error Code EE: Parameter Error
EE on a Federal display refrigerator with a Carel control is a unit parameter reading error. Remedy abnormal operating conditions: the control is rated for 14 to 122 F and less than 90 percent relative humidity, non-condensing. Replace the control if EE persists.
Medium: the case may keep running, but a control that cannot read its parameters needs attention.

What does Federal Industries error code EE mean?
EE is not a probe code. It reports that the control had trouble reading its unit parameters, the stored settings that tell it how to run the case. The manual's remedy is to correct abnormal operating conditions. The control is rated for 14 to 122 F (-10 to 50 C) and for less than 90 percent relative humidity, non-condensing. If the control sees conditions outside that range, its stored data can be disturbed. If the problem persists after the conditions are corrected, the control is replaced. As with other errors, an alarm sounds, the indicator lights and the wrench button mutes it, and codes clear automatically after the cause is fixed.
Affected models and control systems
Federal SSRC and ESSRC display refrigerators with a Carel control. The SSRPF and SSRVS use the same Carel error table.
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
- EE flashes on the display
- An alarm sounds and the alarm indicator lights
- The settings seem to have changed or are not saved
- The case sits in a hot or humid spot
Possible causes
Listed in Federal Industries's documentation
- Operating conditions outside the control's rated range
Other likely causes — what usually sits behind error code EE on this control. A technician confirms which one it is before any part is replaced.
- Condensation on the control from cold-case humidity near an open door
- A power disturbance that corrupted stored parameters
Safe checks before calling for service
- Press the wrench button to mute the alarm.
- Check the temperature and humidity around the control and the case location.
- Move heat or moisture sources away if you can.
- If EE stays, write down the model and conditions, and call us.
How a technician diagnoses error code EE
- Read the code and any others in the cycle.
- Check the ambient temperature and humidity at the control.
- Check for condensation or heat sources.
- Check the supply voltage for disturbances.
- Cycle the power and see whether EE returns.
- Replace the control if it persists.
- Parameter values are specific to the model and are not set by guesswork.
- Control replacement involves mains-powered parts.
- Ambient conditions may need changes to the installation.
How error code EE differs from similar codes
EE is the unit parameter error, and EF is the operating parameter error. Both share the same remedy.
