What the E077 error code actually means

Your Electrolux induction cooktop has detected a problem with the temperature sensor that monitors the right side burners, and the cooktop has shut down those zones as a safety measure. The sensor circuit appears to be broken or disconnected, so the cooktop can no longer confirm it is operating safely. A technician will need to inspect and most likely replace a circuit board to fix this issue.

Questions people ask about E077

What does E077 mean on a Electrolux cooktop?
E077 indicates that the control system has detected a break or open circuit in the heat sink temperature sensor for the right side induction cooking zones. Without a valid reading from this sensor, the cooktop cannot confirm safe thermal operation and disables the affected zones. The fault points to the induction housing assembly on the right side of the unit.
Is it safe to keep using the cooktop while E077 is displayed?
No. The E077 code means the cooktop has lost thermal monitoring for the right side zones, which is a protective system designed to prevent overheating. Continuing to operate the appliance without this protection in place could lead to component damage or a fire hazard. The affected zones should remain off until the fault is resolved.
How much does it cost to repair an E077 error on an Electrolux induction cooktop?
Repair costs depend on whether the issue is a wiring connector, the thermistor, or the full generator circuit board. Generator circuit boards for induction cooktops typically range from $150 to $350 or more for the part alone. Adding professional labor, total repair costs commonly fall in the range of $250 to $550, though prices vary by region and service provider.
Can I fix E077 myself, or do I need a professional?
The primary repair involves replacing the right side generator circuit board, which is a high-voltage induction power component. This repair requires disconnecting power, handling capacitors that can retain charge, and working inside the appliance. It is strongly recommended that a qualified appliance technician perform this repair due to the electrical hazards involved.
Will resetting the cooktop clear the E077 error?
A power reset by turning off the circuit breaker for 30 to 60 seconds may temporarily clear the display, but the error will return once the cooktop runs a self-check and rediscovers the open sensor circuit. Because the fault is caused by a hardware failure in the sensor or circuit board, a reset alone will not fix the underlying problem.
