- Revision Date: 1/24/2025
- Subject: E443 Error Code
- Models: DVMS, ECO, CHILLER, WATER
- Title: Refrigerant Leak Error
- Judgment Method: If the compressor is idle and the pressure is below 14 PSIG on the low side, error E443 will occur.
Troubleshooting Steps
- Connect manifold gauges to the system and verify the standing pressure compared to the ambient temperature using a PT chart.
- Connect a laptop and open Samsung service software (Snet Pro2).
- Verify that the manifold gauges and Snet service software match. If they do not match, test pressure transducers as per the low- and high-pressure transducer chart.
- If the standing pressure is below 14 PSIG while in idle, place the system in vacuum mode, pressure test the system to 500 PSIG with dry nitrogen, and test for leaks.
- Locate and repair leaks, conduct the triple evacuation process, and weigh in charge per the installation manual or DVM pro file.
- Molex connection on the circuit board will be in a different location across models.
- Check the wiring diagram to ensure the proper location.
