The **E-83** display on a Samsung microwave points to **communication error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **E-83**. Search normalization stores it as **E83** while preserving the characters a homeowner actually sees.

Communication error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E83 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. Safety takes priority over clearing E-83. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged.
A returning communication/electronic-control code can require harness, connector, board power-supply, firmware, or module testing. A repeatable E-83 event is more useful diagnostically than repeated resets, because it shows when the communication error check is failing.

We diagnose Samsung microwave no-heat, keypad, sensor and control-related symptoms.
Communication error.
You can try the one reset Samsung documents for the model, but **E-83** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **E-83**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **E-83** before replacing anything.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Microwave E-83** separate from same-looking codes used by other Samsung appliance families.
