For the Samsung Microwave families covered by the source set, **E-82** means **communication short error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **E-82**. Search normalization stores it as **E82** while preserving the characters a homeowner actually sees.

Error codeE82

Quick answer
Communication short error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E82 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
For the Samsung Microwave families covered by the source set, **E-82** means **communication short error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung appliances monitor whether a function reaches an expected state within a certain sequence.

Signs
Symptoms you may notice
One clue that supports the E-82 diagnosis is that the appliance can lose communication between control boards, display, inverter, or other electronic modules.
Depending on the exact model, controls can become unresponsive, a feature may stop, or the code may appear after power-up.
Depending on the exact model, intermittent operation can occur if a connection or power condition is unstable.
While E-82 is active, e-82 appears and the microwave may stop or limit the function associated with communication short error.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
To rule out an accessible cause, power the appliance off once using the documented method, then restore power and see whether the code returns.
Before opening any service area, record whether the issue followed an outage, update, move, or service event.
Before opening any service area, do not reseat internal live connectors unless qualified to follow the exact service procedure.
As an external check for E-82, record the exact code and model number.
Before opening any service area, power the microwave off for 60 seconds only if Samsung's model guidance allows a reset.
As an external check for E-82, do not remove the outer cabinet or access internal high-voltage components.
Important safety warning. When working around a microwave that shows E-82, keep the checks external and non-invasive. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged.

When to request repair service
If the owner-accessible checks do not clear E-82, A returning communication/electronic-control code can require harness, connector, board power-supply, firmware, or module testing. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
You can try the one reset Samsung documents for the model, but **E-82** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
No. **E-82** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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-82** separate from same-looking codes used by other Samsung appliance families.
