What -tE- means on a Samsung range

The -tE- error code on a Samsung range indicates a communication failure between the Sub PCB (printed circuit board) and the touch glass panel. The Sub PCB serves as an intermediary controller that manages the touch interface, relaying input signals from the touch glass to the main control board. When this communication link breaks down, the range cannot process touch commands, and the error is triggered to alert the user and technician that data is not passing correctly between these two components.

The most common starting point for diagnosing this error is connector TE201 on the Sub PCB. This connector is the physical interface that links the Sub PCB to the touch glass assembly. If this connector is loose, partially seated, or has been displaced due to vibration or prior disassembly, communication will be interrupted and the -tE- code will appear. Inspecting and firmly reseating TE201 is always the first step before assuming component failure.

If the connector is properly seated and the error persists, the fault may lie with the wiring harness running between the Sub PCB and the touch glass, the touch glass itself, or the Sub PCB. Damaged wire insulation, corroded connector pins, or a failed touch glass digitizer can all prevent the signal from transmitting correctly. In some cases the Sub PCB itself may have failed and will need replacement to restore proper communication.

Common causes of -tE-

  1. 01

    Loose or unseated connector TE201

    Wiring / connection

    Connector TE201 on the Sub PCB is the primary link between the Sub PCB and the touch glass. If this connector is not fully inserted, communication fails immediately and the -tE- code appears. Inspect and firmly reseat the connector as the first diagnostic step.

  2. 02

    Damaged or faulty wiring harness

    Part replacement

    The wiring harness connecting the Sub PCB to the touch glass can develop breaks, pinched wires, or corroded pins over time. Visually inspect the harness for any signs of wear, heat damage, or bent terminals at each connector end.

  3. 03

    Failed touch glass assembly

    Part replacement

    If the touch glass digitizer has failed internally, it will not send or receive signals from the Sub PCB, triggering the communication error. Swapping the touch glass is required to confirm this as the cause.

  4. 04

    Defective Sub PCB

    Part replacement

    If the connector and wiring check out correctly but the error remains, the Sub PCB itself may have failed. A faulty Sub PCB cannot maintain the communication protocol with the touch glass and will need to be replaced.

Frequently asked questions about -tE-

What does -tE- mean on a Samsung range?
The -tE- error code indicates a communication failure between the Sub PCB and the touch glass panel on your Samsung range. The Sub PCB is the controller that links the touch interface to the main control system, and this code appears when that connection breaks down. The most likely cause is a loose connector, specifically connector TE201 on the Sub PCB. Reseating that connector is the recommended first diagnostic step.
Can I fix the -tE- error on my Samsung range myself?
In some cases, yes. If the error is caused by a loose connector TE201 on the Sub PCB, a knowledgeable DIYer comfortable working inside appliances can reseat the connector and resolve the issue without replacing any parts. However, if the problem is a damaged wiring harness, a failed touch glass, or a defective Sub PCB, those repairs involve sourcing and installing components and may be better suited for a qualified technician.
Is it safe to use my Samsung range while the -tE- error is showing?
A -tE- error means the touch control interface is not communicating properly, which can make the range unreliable or unresponsive to input. It is best to avoid using the range until the error is resolved, as you may not be able to control cooking functions accurately or shut off burners through the touch panel.
Will resetting my Samsung range clear the -tE- error?
A power reset, such as unplugging the range or switching off the circuit breaker for a few minutes, may temporarily clear the error code. However, if the underlying issue is a loose connector, damaged harness, or failed component, the code will return once the range powers back on. A reset alone does not fix the root cause of the communication failure.
How much does it cost to repair a Samsung range -tE- error?
Repair costs vary depending on the cause. If only the connector needs reseating, there is no parts cost, and a service call fee typically ranges from $75 to $150. If a wiring harness or touch glass replacement is needed, parts plus labor can bring the total to $150 to $400 or more. A Sub PCB replacement tends to be on the higher end of that range due to part cost.
