Airtemp Mini Split EE Error Code: What It Means & What to Check
Q: My Airtemp mini split is showing EE. What does that mean?
A: On many Airtemp (and similar platform) mini splits, EE commonly indicates a drive memory chip error. In plain terms, the driver/inverter section is detecting a memory/storage fault and may shut the system down to protect operation and prevent unreliable control behavior.
This guide covers homeowner-safe checks you can try first, common causes, and when it’s time to call our friendly technicians in yellow.
Symptoms You May Notice
- EE appears on the indoor unit display
- System may not start at all
- Outdoor unit may attempt startup, then shut down
- Cooling/heating is interrupted or unavailable
- Error may clear after a reset, then return
Safety First
- Turn the system off before checking filters or visible airflow restrictions.
- Do not open electrical panels, inverter covers, or control compartments unless you are trained.
- Mini split electronics can store hazardous voltage—avoid touching internal components.
- Drive memory/inverter faults require electrical testing and model-specific diagnostics.
Quick Checks You Can Try First
1) Power Reset (Quick Reboot)
Turn the mini split off, then reset power at the breaker for about 3–5 minutes. Restore power and test the system again. If EE returns, the memory/drive fault is likely still present.
2) Check for Recent Power Events
If the error started after a storm, outage, voltage flicker, or breaker trip, make a note of it. Electronics and memory-related faults can appear after power disturbances.
3) Check and Clean the Indoor Air Filter (Baseline Check)
EE is not primarily an airflow code, but cleaning the indoor filter is still a good homeowner-safe baseline step while troubleshooting.
4) Watch for Repeat Pattern
Note whether EE appears immediately at power-up, at startup, or after the outdoor unit begins running. That timing can help a technician narrow down control vs. driver/inverter faults.
Common Causes of EE Drive Memory Chip Error
- Driver / inverter board memory chip fault
- Main control ↔ driver data fault (communication/data integrity issue)
- Power event damage (surge, voltage spike, outage-related stress)
- Board-level component failure in the drive electronics section
- Connector/wiring issue affecting driver board operation (less common than board failure)
Likely Components a Technician May Check
- Driver / inverter board (including memory chip-related faults)
- Main control board (model-dependent)
- Communication harnesses and connector points
- Power input quality and signs of surge/heat damage
- Outdoor electronics compartment condition (moisture, corrosion, contamination)
When to Call Beacon
If EE returns after a reset, the system likely needs professional diagnosis. Drive memory chip errors usually require board-level diagnostics and model-specific testing procedures, and often point to an electronics repair/replacement path.

Frequently Asked Questions
What does EE mean on an Airtemp mini split?
EE commonly indicates a drive memory chip error, meaning the driver/inverter electronics detected a memory-related fault.
Can a storm or power outage cause an EE code?
It can. Power disturbances can stress electronics and sometimes trigger memory or inverter board faults.
Can I reset an EE code?
You can try one breaker reset, but if EE returns, the system likely has a driver/inverter or control electronics issue that needs diagnosis.
Is EE a refrigerant problem?
Usually no. EE is generally an electronics/driver memory fault, not a refrigerant pressure or charge code.
Should I keep running the system with EE?
If EE keeps returning, it’s best to stop and schedule service. Repeated electronics faults can prevent reliable operation and may worsen board damage.
When should I call for service for EE?
If EE returns after a breaker reset, call for service to diagnose the driver/inverter board, control board, and related wiring/electronics.
