Senville EH 02 error code: zero-crossing signal fault
Senville EH 02 meaning for applicable LETO and AURA equipment, its AC-fan-motor scope, safe restart guidance, and service boundary.
What this means
Senville says EH 02 on applicable LETO and AURA equipment means the indoor PCB is not receiving the expected zero-crossing feedback associated with the AC fan motor; it does not apply the same way to DC-motor designs.
Equipment and model context
LETO and AURA models using an applicable AC fan motor
- Senville LETO models with the applicable AC fan design
- Senville AURA models with the applicable AC fan design
Codes can change meaning across product families. Confirm the complete model number on the data plate before applying any code definition.
What you may notice
- The indoor display shows EH 02 and indoor fan operation may be interrupted.
Likely causes
- A wiring or power-supply issue can interrupt the expected feedback signal.
- The indoor control board may be faulty after wiring and supply are verified.
Safe homeowner checks
- Confirm the exact series and whether the model uses the applicable AC fan motor before using this diagnosis.
- Turn off system power completely, wait two minutes as Senville directs, and observe whether the code returns.
Is a reset appropriate?
Senville specifies one complete two-minute power-off restart; recurrence means the fault needs service.
When to call a technician
- If the code remains, wiring, supply, fan design, and indoor PCB checks belong with qualified service.
- Do not access the indoor electrical enclosure or test energized components.
