Bonjour, J'ai une unité intérieure RSA12LCC et une unité extérieure ROR12LCC. cette climatisation fonctionne tres rarement .Actuellement cette climatisation est en panne. le compresseur ne demare pas. Le ventilateur fonctionne 10 secondes puis s'arrete.J'ai mesuré les enroulements 0.8ohms sur chaque enroulements. j'ai forcé le demarrage du compresseur par l'intermédiaire de la telecommande mais le compresseur ne demarre pas egalement. Quelqu'un a il un conseil. merci d'avance

To troubleshoot a Fuji Electric RSA12LCC indoor unit and ROR12LCC outdoor unit that is not starting and has a non-functioning compressor, follow these steps:

1. Check Power Supply: Ensure the unit is receiving proper voltage. Verify connections at terminals marked N and L.

2. Inspect Fuse: Check the fuse (250V 20A) on the outdoor unit. Replace if blown.

3. Examine Thermistors: Verify the resistance of the pipe and outdoor temperature thermistors. Faulty thermistors can prevent operation.

4. Check Compressor Relay and Wiring: Inspect the relay connections and wiring from the control PCB to the compressor.

5. Review Error Codes: Refer to the error contents section in the manual to identify any displayed fault codes.

6. Inspect PMV and 4-Way Valve: Ensure power and control signals are reaching the PMV (Pulse Motor Valve) and 4-Way Valve.

7. Check Indoor/Outdoor PCB Boards: Look for visible damage or faulty components on the PCBs.

If any component is damaged or not functioning properly, it may need to be repaired or replaced.
