Electric test to the compressor:
The compressor has some electrical connections and a temperature limiter thermostat that ensure its protection.
Using a multimeter, is possible to control its functionality, nevertheless the HMI will detect if compressor is running.
Cables and cover protection have clear identification of the different connections.
R – Main electro valve
S – Auxiliary electro valve
C – Common

Checking Continuity and Resistance (Ω)
Between C – R > 0 Mitsubishi = 4.7 Ω / Highly = 5.84 Ω
Between C – S > 0 Mitsubishi = 8.2 Ω / Highly = 7.62 Ω
Between R – S > 0
