Replacement Delfield 2194808 Defrost Probe 12-Month Warranty & USA Support

Restore reliable evaporator coil and defrost temperature monitoring with the Wholesale Sensors Replacement for Delfield 2194808 Defrost Probe, backed by a strong 12-Month Warranty and responsive USA-based product support. Designed for compatible Delfield commercial refrigerators, freezers, work tables, equipment stands, prep tables, and reach-in refrigeration equipment, this replacement temperature probe provides the feedback required by compatible refrigeration controls to monitor evaporator conditions and support proper defrost operation.

The Delfield 2194808 is specifically identified by Delfield as a coil/defrost probe used with compatible Danfoss refrigeration controls. Current Delfield parts documentation describes 2194808 as a “Probe, Defrost, Danfoss” and identifies it as the blue probe in applicable equipment. This distinction is important because many Delfield refrigeration systems use more than one temperature sensor, with each sensor assigned to a different monitoring position.

This Wholesale Sensors component is engineered as a perfect OEM-style replacement designed to meet or exceed OEM specifications for compatible 2194808 applications. The primary manufacturer number is 2194808. Parts Town also identifies 2195551 as a previous part number associated with the current 2194808 defrost probe.

Do not confuse this sensor with Delfield 2194809. Official Delfield documentation identifies 2194808 as the coil/defrost probe, while 2194809 is separately identified as the air/cabinet sensing probe. Although both sensors may appear in the same refrigeration equipment, they serve different sensing positions and should not automatically be treated as interchangeable.

Compatibility covers a broad range of Delfield commercial refrigeration equipment. Parts Town identifies popular 2194808 applications including F15MC48N, 18648-PTB, and CTP8175-NB. Delfield’s own current parts documentation confirms 2194808 in multiple commercial refrigeration product families.

The probe is documented in Delfield GCF3P, GBF3P, and GBSF3P equipment, where it is identified as the coil/defrost probe used alongside the separate 2194809 air/cabinet sensor. These are current Delfield refrigeration applications using the 2194808 Danfoss defrost probe.

Delfield also specifies 2194808 in select GARRI1P-G, GARRI1P-S, and GARRT1P-S reach-in equipment. In these applications, the official parts documentation describes 2194808 as a 120-inch-long defrost probe for Danfoss control systems, specifically for applicable units without touchscreen controls. This is an important compatibility detail because touchscreen-equipped versions can use a different sensor arrangement.

The sensor is also documented throughout Delfield’s F18 Series refrigerated work tables. Delfield service documentation lists 2194808 with refrigerator and freezer evaporator coil assemblies, alongside the separate 2194809 temperature sensor.

Additional documented applications include Delfield F2000 and F17 Series equipment stands, where 2194808 is listed as the defrost probe associated with compatible evaporator coil assemblies.

Because Delfield has manufactured many equipment configurations, refrigerant versions, control revisions, and production changes, compatibility should always be verified using the complete equipment model number, serial number, original sensor part number, probe color, connector configuration, and control type. Do not order a replacement based only on the general appearance of the equipment.

The 2194808 performs an important role in commercial refrigeration. During operation, moisture can collect and freeze on an evaporator coil. A refrigeration system must manage frost correctly to maintain efficient airflow and heat transfer. The defrost control system relies on accurate temperature information to understand conditions at the evaporator.

The 2194808 probe supplies temperature information from the coil/defrost sensing position to the compatible Danfoss control. Delfield specifically identifies this component as a defrost probe rather than a general cabinet temperature sensor.

When the original sensor deteriorates, becomes electrically open or shorted, develops an intermittent connection, or provides inaccurate temperature feedback, the refrigeration controller may not receive an accurate representation of evaporator conditions.

Potential symptoms can include abnormal defrost operation, excessive frost or ice accumulation on the evaporator, inconsistent cabinet temperatures, reduced airflow through an iced evaporator, unusual refrigeration cycling, or other temperature-related control problems.

These symptoms do not automatically mean the 2194808 probe has failed. Commercial refrigeration systems contain numerous components that can cause similar problems. Proper diagnosis should also include the evaporator coil, evaporator fan, defrost system, controller, wiring, connectors, airflow, condenser condition, refrigerant system, expansion valve, door seals, and related electrical components.

Before replacing the sensor, inspect the existing probe and its wiring carefully. Look for damaged insulation, cut or pinched wires, loose terminals, corrosion, moisture intrusion, broken conductors, damaged connectors, or physical damage to the sensing element.

A qualified refrigeration technician can also test the sensor electrically. The probe should provide the temperature-dependent electrical response expected by the compatible Danfoss controller. Testing should be performed using the correct Delfield service information for the specific equipment rather than assuming every commercial refrigeration thermistor uses the same resistance curve.

Installation should begin by disconnecting electrical power to the refrigeration equipment according to the manufacturer’s service procedures. Commercial refrigeration systems contain hazardous electrical voltage, moving fan components, hot surfaces, and pressurized refrigerant circuits, so qualified service personnel should perform repairs when appropriate.

Before removing the original 2194808 probe, document its mounting location, orientation, wire routing, connector position, and relationship to the evaporator coil. Taking photos before disassembly can help ensure the replacement is installed in the correct location.

Remove the existing probe carefully without damaging the evaporator coil, wiring harness, or mating connector. Inspect the electrical connection before installing the replacement. Corroded, overheated, loose, or damaged terminals should be corrected rather than simply connecting a new probe to a compromised circuit.

Install the Wholesale Sensors replacement in the same intended coil/defrost sensing location as the original 2194808. Correct probe placement matters because even a properly functioning sensor can provide misleading temperature information when mounted in the wrong position.

Route the wiring according to the original configuration. Keep the lead protected from sharp sheet-metal edges, moving fan blades, inappropriate contact with hot components, and areas where service panels could pinch the wiring.

After installation, reinstall all covers and guards, restore electrical power, and allow the refrigeration equipment to complete normal cooling and defrost cycles. Monitor cabinet temperature, evaporator frost condition, and defrost performance to confirm proper operation.

Commercial refrigeration equipment does not use automotive OBD-II diagnostic trouble codes, so automotive sensor codes do not apply to Delfield 2194808. Delfield and Danfoss controls may provide equipment-specific alarms or diagnostic indications depending on the model and controller. Always use the service documentation for the exact equipment when interpreting a displayed fault.

It is also important to identify the correct sensor before replacement. In many documented Delfield applications, 2194808 is the coil/defrost probe while 2194809 is the air/cabinet probe. Replacing the wrong sensor may not correct the refrigeration problem.
