Dead Inverter


Basic fault

  • Check inner and outer fuse
  • Try checking drive voltage of mosfet
  • The inverter shuts down 2 to 5 minutes after being switched on due to a faulty or stopped fan. This causes the heat sink to overheat, ultimately leading the inverter to turn off. Video @ 7:45
  • Try tracing the outgoing voltage fault systematic wise e.g. check for short or faulty components

Luminous Ecowall 900 VA

Problem Dead Inverter
Fault Blown R60 Fuse resistor and Swollen capacitors due to unknown reason
Fault tracing Basic check inner and outer fuse and then First traced for 12v supply in the 12+ written connector, found no supply > Next traced for 5v in the 20th pin of the microcontroller, found no supply > Next traced for three pin regulator IC for voltage which converts 12v to 5v, found no supply >Next traced the R12 fuse resistor which was found OK > Next traced the next R60 fuse resistor of 1 Ohm attached to regulator IC of the micro controller, found broken, Changed the resistor and inverter started working. Also the two long capacitors between the heat sink were swollen, they were also changed. Video
Parts used Resistor and capacitors

Luminous Ecowall 950 VA

Problem Dead Inverter
Fault Blown R60 Fuse resistor and Swollen capacitors due to fan stopped by dust clogging
Fault tracing
  • Directly found Swollen resistors and faulty c60 fuse resistor, changed the fan, capacitors and fuse resistors and solved the problem. Video.
