E2
Daikin Split AC
Severity: ModerateWhat Does This Error Mean?
E2 on a Daikin AC typically indicates a fault with the indoor fan motor or the zero-crossing detection circuit. The indoor fan circulates room air over the evaporator coil — without it, cooling cannot reach the room. Some Daikin models also use E2 for anti-freeze protection activation when the indoor coil is close to freezing.
Affected Models
- Daikin FTKF Series
- Daikin FTKG Series
- Daikin ATKF Series
- Daikin Inverter Split AC (all models)
- Daikin 1 Ton / 1.5 Ton / 2 Ton Inverter
Common Causes
- Indoor fan motor bearing failed — motor is seizing or drawing excessive current
- Indoor fan blade obstructed — debris or an object has jammed the fan
- Fan motor capacitor failed — motor cannot start or maintain speed
- Zero-crossing detection circuit fault on the indoor PCB
- Indoor coil approaching freeze — triggered as a protective measure on some models
How to Fix It
-
Switch off the AC and listen — does the indoor fan make any noise when starting?
A fan that hums but does not spin has a seized bearing or failed capacitor. Complete silence suggests a power supply fault to the motor.
-
Clean the indoor unit air filter.
A severely blocked filter can cause the indoor coil to start freezing, triggering E2 as a protective code on some Daikin models.
-
Power cycle — switch off at circuit breaker for 10 minutes, then restart.
If E2 was triggered by a temporary coil freeze event, the system may clear after the coil defrosts.
-
If E2 persists, call Daikin service for indoor fan motor inspection.
Fan motor replacement is a moderate-cost repair — typically Rs 800–2,500 for the motor plus visit charge.
When to Call a Professional
E2 requires a technician to inspect the indoor unit. The indoor fan motor is inside the indoor unit casing — accessing it requires disassembly. Daikin India: 1800-103-3666.
