Sub-Zero EE Code and a Flashing Wrench or Service Light
EE is one of the more specific Sub-Zero codes, because the side of the display it appears on tells you which compartment’s sensor is suspect.
EE According to Sub-Zero
On Classic Series (BI) built-ins, Sub-Zero pairs EE with a flashing service wrench; on UC undercounter models, with a flashing Service message. In both, Sub-Zero links the code to a faulty thermistor, the temperature sensor: EE on the left points to the freezer thermistor and EE on the right to the refrigerator thermistor. Sub-Zero states that no troubleshooting is available for this issue and directs owners to its Factory Certified Service, with the code and current temperatures.

How EE Shows Up
Often with these.
Likely Sources
Sub-Zero names the sensor; we confirm it before ordering.
Getting Ready for an EE Repair
There is no owner fix in Sub-Zero’s article, but a few notes save time.
Note the side
Left means freezer sensor, right means refrigerator sensor, by Sub-Zero’s description.
Check temperatures
A thermometer in the affected section shows whether the food is still safe.
Find the model number
The rating plate inside the unit lets a technician confirm the correct sensor before the visit.
When to Call a Technician
Schedule a repair if:
- EE appears on either side
- The wrench or Service light keeps flashing
- One section drifts warm or cold
- You need the sensor tested

Sub-Zero EE FAQs
Sub-Zero links EE to a faulty thermistor. On the left side it points to the freezer sensor; on the right, the refrigerator sensor.
Sub-Zero’s EE articles state that no troubleshooting is available and list no reset. The sensor needs to be tested.
Sub-Zero publishes EE articles for Classic Series (BI) built-ins and UC undercounter models, and a separate answer notes that 400 Series units can show Service and EE too.
It depends on the model and access, so we test first and give you a written estimate before any work.
