What does Samsung Microwave TE Error - Causes & Fix mean?

TE means touch communication error: the control board can't reach the keypad. Most likely fix: power reset or replace the membrane switch.

How do I fix Samsung Microwave TE Error - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Samsung Microwave TE Error - Causes & Fix?

The most frequently replaced parts for Samsung Microwave TE Error - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Samsung Microwave TE Error - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Samsung Microwave TE Error - Causes & Fix

Samsung Microwave TE Error — What It Means

TE stands for Touch communication Error on Samsung microwaves. The main control board has lost proper communication with the touchpad or membrane switch panel. Samsung documents this as a fault in the keypad circuit or the connection between the user interface and the control system. The error often appears after moisture exposure, a failed keypad membrane, or a loose connector between the touch panel and the main board.

Jump to Fix

Common Causes

Failed or open membrane switch The touchpad assembly itself develops an open circuit or short that prevents the control board from reading button presses.
Loose or corroded connector The ribbon cable or plug between the keypad and main control board is loose, corroded, or contaminated.
Moisture or spill intrusion Liquid or steam has entered the touch panel electronics and disrupted the communication circuit.
Defective main control board The control PCB itself has a fault in the touch-input communication circuitry.

Step-by-Step Fix

Unplug the microwave or turn off the circuit breaker for at least 60 seconds to perform a full power reset, then restore power and test the keypad.
Inspect for moisture around the control panel and keypad area. If you suspect liquid intrusion, leave the unit unplugged and allow the electronics to dry for several hours before retesting.
Remove the outer cover or control panel trim to access the membrane switch assembly and the ribbon cable that connects it to the main control board.
Check all connectors between the touchpad and the control board. Reseat each plug firmly and inspect for corrosion, bent pins, or contamination.
Test the membrane switch by disconnecting it and measuring continuity across each button contact while pressing. Replace the touchpad assembly if you find open or intermittent contacts.
Replace the main control board if the keypad and all wiring are intact but the TE code still appears after power reset.
Reassemble and test by cycling through several keypad inputs and running a short heat cycle to confirm proper operation and no return of the error.

Parts Often Needed

Part	Notes
Membrane switch / touchpad assembly	Amazon \| Most common repair for TE errors. Match your exact Samsung microwave model number.
Main control board / PCB	Amazon \| Required if the touch-input circuit on the board itself has failed. Verify the keypad is good first.
Ribbon cable / wiring harness	Amazon \| Only if the existing cable is visibly damaged, cut, or corroded.

When to Call a Pro

Call a qualified appliance technician if the TE code returns after a power reset and you are not comfortable opening the microwave cabinet or working near the high-voltage capacitor and magnetron. Microwaves store dangerous voltages even when unplugged. A technician can safely discharge the capacitor, trace the communication circuit with a multimeter, and replace the touchpad or control board with the correct Samsung part for your model.
