What does Gree error F2 mean?
F2 means the temperature sensor on the indoor coil is not giving a proper reading. The sensor is faulty, its wire is loose, or the board cannot read it.
Why does code F2 appear?
- The sensor's plug has come loose from the board.
- The sensor or its wire is broken or got wet.
- The indoor board is faulty.
What can you safely check for F2?
- Switch the power off for 5 minutes, then start the AC again.
- Check whether water drips from the indoor unit. Water can damage the sensor.
Safety: never reach into an electrical panel, board, gas pipe or the inside of an inverter yourself. You can get a shock or release gas. This is a mistri's job.
When should you call a mistri?
If the code comes back, call a mistri. A sensor is a cheap part and usually quick to change, but the indoor unit's cover and board must be opened for it.
