Disconnect power. Use a multimeter to check the continuity of the start relay and overload. Replace if open-circuit. Issue 2: Compressor is Running but Not Cooling Cause: Refrigerant leak or inefficient compressor valves.
: Utilizes a piston-driven reciprocating mechanism suitable for demanding commercial refrigeration environments. Energy Efficient
Measure between each terminal pin (C, R, and S) and a bare, unpainted metal surface on the compressor shell. Any continuity or low-resistance reading indicates an internal short-to-ground, requiring immediate replacement. Critical Handling and Installation Rules
The string “l68wu1” could be:
Proper system integration requires strict adherence to the electrical boundaries defined by Donper. Operating outside these ranges can cause premature motor insulation breakdown or failure of the start components.
