Blendtec Commercial Blender Error Code Temp Sensor: Not Detected

Error: Temp. Sensor not detected on a Blendtec commercial blender means the control cannot see the motor temperature sensor. The manual lists it under Reset Errors: press the cancel button or unplug the blender and plug it back in, and contact your Blendtec service agent if it does not clear.

Medium · inspection needed

Medium: the control cannot read motor temperature, so the blender may refuse to run until repaired.

What does Blendtec error: temp. sensor not detected mean?

The control needs to read the motor temperature so it can protect the motor from overheating. To do that it checks that the temperature sensor is present and answering. If the sensor does not respond, the control shows Error: Temp. Sensor not detected, because it cannot tell how hot the motor is. The manual lists the message with the other Reset Errors for the Stealth 875/885 and Connoisseur 825. The action is to press the cancel button or cycle power by unplugging the blender and plugging it back in, and, if the error does not clear, to contact your Blendtec service agent. No individual causes are listed. A sensor that has failed, a connection that has come loose, or a control board input that is not reading are likely causes. The display reads exactly Error: Temp. Sensor not detected.

Possible causes

Sensor connector loose or corroded inside the base
Sensor circuit reading on the control board not responding

Safe checks before calling for service

✓ What an operator can do

Press the cancel button, or unplug the blender and plug it back in, as the manual says.
Try a short blend and see whether the error returns.
Do not open the base or move wires yourself.
If the error does not clear, contact your Blendtec service agent and note whether the blender ran at all, for the service call.

How a technician diagnoses error: temp. sensor not detected

Read the error and confirm it is the sensor message and not an overtemp message.
Check the sensor connector and wiring for looseness or corrosion.
Measure sensor resistance against its specification.
Check the sensor input on the control board.
Replace the sensor or lead, or the board if the input fails, and run a loaded test.

! Leave this to a technician

Sensor and board tests mean opening a base connected to line voltage.
Running a blender without a working temperature sensor risks undetected overheating.
Resistance values and replacement parts must match the model.

Error: Temp. Sensor not detectedQuestions about Blendtec error: temp. sensor not detected

Can I keep using the blender with this error?

If a power cycle clears it, you can. If it returns, contact your Blendtec service agent, since the motor cannot be monitored.

Is it the same as Overtemp?

No. Overtemp means the motor was too hot. Temp. Sensor not detected means the control cannot read the temperature at all.

Will unplugging it fix a failed sensor?

No. A reset clears a brief glitch, but a failed sensor will bring the error back.
