- The E-396/496 I have seen the most, these are usually a result in losing the VDC from the EMI or Transformer to the Inverter or Inverter to the Fan PCB Board.
- Losing one fuse on EMI#1 or one leg from the Transformer will generate these alarms.
- EMI failure Losing voltage at CN23 to CN13 at the inverter will generate this alarm .
- Inverter board failure will generate this, the VDC from the CN15 Connector form the inverter to the CN401 at the FAN PCB connector is the path that would generate this.
- This voltage as per Samsung Engineering should be (Voltage in DC Link is below 150V or over 410V.)
-
- Below is the troubleshooting tree for E-369/396/469/496 as listed in the Error codes and diagnostics Manual.
- VRF-SVM046A-EN
- As per Samsung Engineering on the Inverter Reactors :
- The L (Inductor) in the LC filter applied to the inverter product.
- Inverters convert AC input power into DC power and then use PWM (Pulse Width Modulation) to generate AC output at the desired frequency.
- LC filters are designed to address harmonics and power factor degradation that occur when converting AC input to DC.
- Transpower part number:
CNT06987 2 1 CONTROL; TRANSPOWER
DC Link Voltage Sensors Errors E469, E496, E369, & E396
