Avantco 17813890 Carel Black Temperature Probe Sensor – 59"

Avantco 17813890 Carel Black Temperature Probe Sensor – 59"

The Avantco 17813890 is a Carel black temperature probe sensor designed for compatible Avantco commercial refrigeration equipment. This replacement sensor measures approximately 59 inches long and is used with compatible Carel electronic temperature controllers.

The temperature probe provides the controller with the temperature input it needs to monitor refrigerated cabinet conditions. Accurate sensor input is important because the electronic controller relies on the probe reading when responding to temperature changes in the equipment.

Use Avantco manufacturer part number 17813890 as the primary identification reference when selecting this replacement. Always compare the original sensor, controller, equipment model, connector configuration, cable routing, and equipment documentation before ordering.

What the Avantco 17813890 Temperature Probe Does

The Avantco 17813890 senses temperature inside compatible refrigeration equipment and sends that temperature information to the connected Carel controller.

The electronic temperature controller uses the probe input as part of the equipment's refrigeration-control sequence. If the sensor signal is inaccurate, intermittent, or missing, the controller may not receive a correct representation of actual cabinet temperature.

Designed for Carel Temperature Controllers

Avantco identifies the 17813890 specifically as a Carel black probe sensor. It is intended to replace the temperature sensor used with compatible Avantco Carel temperature-control systems.

Do not substitute another sensor based only on cable color or physical appearance. Different probes can use different electrical characteristics, cable lengths, connectors, and equipment applications.

59-Inch Probe Cable

The Avantco 17813890 has an approximate overall length of 59 inches. The cable allows the sensing portion of the probe to be positioned in its intended refrigeration location while connecting back to the Carel controller.

When installing the replacement probe, follow the original cable-routing path whenever possible. Avoid pinching, cutting, stretching, or routing the cable against sharp sheet-metal edges, fan blades, hot components, or other areas that could damage the sensor wiring.

Commercial Refrigeration Applications

The 17813890 is used with compatible Avantco commercial refrigeration equipment equipped with the applicable Carel temperature-control system.

Avantco uses multiple temperature probes across different refrigerators, freezers, display cases, and equipment generations. Always verify the exact manufacturer part number and original sensor before replacement.

Common Signs a Temperature Probe May Need Service

• Displayed cabinet temperature is inaccurate
• Temperature reading changes erratically
• Controller indicates a sensor-related fault
• Probe cable is cut, pinched, or damaged
• Sensor connection is loose or corroded
• Displayed temperature remains fixed while actual cabinet temperature changes
• Controller operation appears inconsistent with actual cabinet temperature
• Probe fails electrical or resistance testing during diagnosis

These symptoms do not automatically confirm that the temperature probe has failed. Wiring, connectors, controller problems, incorrect probe placement, or other refrigeration-system conditions can cause similar symptoms.

Technician Service Information

Before replacing the Avantco 17813890, inspect the complete sensor circuit and compare the displayed cabinet temperature with a known accurate test thermometer.

Check:

• Original 17813890 sensor identification
• Probe cable condition
• Controller connections
• Sensor mounting location
• Cable routing
• Carel controller operation
• Actual cabinet temperature compared with displayed temperature

After installation, secure the probe in the correct sensing location and confirm that the controller displays a reasonable temperature that responds normally as cabinet temperature changes.

Before You Order

Confirm Avantco manufacturer part number 17813890 before ordering. Do not select a temperature probe based only on its black cable or overall appearance.

Verify the following:

• Avantco manufacturer part number 17813890
• Carel temperature-controller application
• Approximately 59" cable length
• Equipment model number
• Original temperature probe
• Sensor connector or terminal configuration
• Probe mounting location
• Original cable-routing path

If the original manufacturer number cannot be confirmed, compare the equipment model, controller, sensor connection, probe length, and existing component before ordering.

Frequently Asked Questions

What is Avantco part number 17813890?
Avantco 17813890 is a black Carel temperature probe sensor used with compatible Avantco commercial refrigeration equipment.

How long is the Avantco 17813890 temperature probe?
The probe is approximately 59 inches long.

What controller is Avantco 17813890 used with?
Avantco identifies 17813890 as a replacement sensor for compatible Carel temperature controllers.

Is Avantco 17813890 a temperature controller?
No. It is the temperature-sensing probe. The Carel controller is a separate component that receives and processes the probe's temperature input.

Can a bad probe cause an incorrect temperature display?
Yes. A damaged sensor, cable, connection, or sensor circuit can contribute to inaccurate or unstable temperature readings.

Can I use another black Avantco probe instead?
Do not assume black probes are interchangeable. Avantco uses different sensor part numbers, cable lengths, and equipment applications. Match the exact manufacturer number whenever possible.

What should I check before replacing the probe?
Compare the displayed temperature with an accurate test thermometer and inspect the cable, connections, controller, and probe placement before replacing components.

How do I confirm Avantco 17813890 is the correct replacement?
Match manufacturer part number 17813890 and verify the equipment model, Carel controller, 59-inch probe length, connector arrangement, and original sensor before ordering.
