- A recent number of calls are coming in for the E-466 And E-366 Alarms.
- I reached out to Samsung Engineering in Korea for Troubleshooting direction.
- We are seeing a wide ranges of VDC At the CN15 on the Inverter Board the sends the VDC to CN401 At the FAN PCB.
- This is the Ranges they sent to reference (Voltage in DC Link is below 150V or over 410V.)
- Reference Troubleshooting Tree.
- 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.
