LG Microwave Error Code E-35

E-35 indicates a weight sensor error where the initial calibration value (called the K value) calculated by the weight sensor is outside the acceptable range of plus or minus 28 in hexadecimal. This means the sensor is not initializing correctly to its baseline zero reference. The error prevents the microwave from using weight-based automatic cooking functions until the issue is resolved.

The E-35 error specifically affects the weight sensor system used for automatic and sensor-based cooking programs. Basic microwave functions may still operate, but any cooking mode that relies on the weight sensor will not work correctly. It is best to avoid using automatic weight-based programs until the fault is diagnosed and repaired to prevent improper cooking results.

Repair costs vary depending on the root cause. If only wiring or connector issues are found, labor costs alone may range from roughly 75 to 150 dollars. Replacing a faulty weight sensor typically adds a parts cost on top of labor, bringing the total to approximately 100 to 250 dollars or more depending on the specific model and local labor rates. If the control board needs replacement, costs can be higher.

Some basic checks are possible without professional help, such as cleaning the turntable area, reseating the turntable, and looking for any visible wiring issues. However, actually testing the weight sensor's output signal and replacing components requires technical knowledge and appropriate tools. If the basic checks do not clear the error, a qualified technician should inspect the sensor and wiring harness.

A power reset by unplugging the microwave for a few minutes may temporarily clear the error if it was caused by a one-time signal anomaly during startup. However, if the underlying cause is a faulty weight sensor, damaged wiring, or physical interference, the E-35 code will return when the appliance initializes again. A reset is worth trying first, but persistent errors require diagnosis of the sensor and its circuit.
