Refrigerator and freezer fail to maintain temperature; food warms and spoils. Compressor does not run due to failed inverter board preventing speed control signals.
All functions — compressor, evaporator fan, condenser fan, and interior LED lights — shut off simultaneously. Classic symptom of a shorted or burned inverter board, especially after a power surge.
Relay clicking noise near the compressor but it never sustains a run cycle. The inverter board fails to deliver proper variable-frequency drive signal to the Embraco compressor motor.
Fridge cools for a while then stops, or temperature fluctuates widely. Caused by degraded solder joints or failing relay on the inverter board intermittently losing control of compressor speed.
Control panel displays error codes related to compressor communication or temperature out-of-range. A faulty inverter board breaks communication between the main control board and compressor, triggering diagnostic faults.



💡 Pro Tip: How to Confirm Your Inverter Board Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Refrigerator completely dead — compressor, fans, and interior lights all stop working simultaneously after a power event
⚠️ Fridge not cooling or cooling inconsistently despite the compressor occasionally humming
⚠️ Error codes related to compressor or temperature sensor communication displayed on the control panel
⚠️ Clicking or rapid relay-cycling sounds near the compressor with no sustained run cycle
🔍 Quick test: Unplug the fridge for 60 seconds, then plug back in. If LEDs flash momentarily then go dark and the compressor never starts, the inverter board is the prime suspect. Always verify the compressor itself is not mechanically seized before ordering the board.
