Replacement Master-Bilt 19-13968 NTC Thermistor Probe Assembly, 10FT Evaporator Inlet/Outlet Sensor, 12 Month Warranty & USA Support

Restore accurate temperature monitoring in compatible commercial refrigeration equipment with the Wholesale Sensors Replacement for Master-Bilt 19-13968 NTC Thermistor Probe Assembly. Designed as a perfect OEM-style replacement, this temperature sensor is engineered to meet or exceed original functional specifications while providing reliable temperature feedback for compatible Master-Bilt refrigeration systems and electronic controllers.

Replacement for Master-Bilt 19-13968

The primary replacement number is Master-Bilt 19-13968, also commonly cataloged as MB19-13968. This component is identified as an NTC thermistor probe with a 10-foot cable. Parts Town documents previous part numbers MB19-13760, MB19-13775, and NOR151553, while RHS catalogs the same 19-13968 thermistor probe under its reference 37-001. Parts Town

The 10-foot cable provides the length needed to route the temperature probe between the sensing location and compatible refrigeration controller. Always verify the complete equipment model, controller configuration, sensor location, and original 19-13968 part number before ordering.

Compatible Master-Bilt Refrigeration Equipment

The Master-Bilt 19-13968 is designed for commercial refrigeration applications. Parts Town identifies popular compatible equipment including MAC-7, MAC-8, and Master Controller 2.0v24. The sensor is also cataloged within the probe and sensor parts for Master-Bilt BRS built-up remote condensing unit equipment. Parts Town

Because Master-Bilt refrigeration systems can be configured differently depending on the controller, evaporator, condensing unit, and equipment generation, compatibility should be confirmed by part number instead of relying only on the equipment family.

NTC Thermistor Temperature Monitoring

The 19-13968 uses an NTC thermistor, or Negative Temperature Coefficient thermistor. An NTC thermistor changes electrical resistance as temperature changes. The compatible refrigeration controller interprets that resistance to determine the temperature measured by the probe.

Master-Bilt’s controller documentation explains that its solid-state temperature sensors change electrical resistance in response to temperature changes. This allows the controller to monitor refrigeration conditions and make operating decisions based on sensor feedback. Master-Bilt

Depending on the exact Master-Bilt controller and equipment configuration, temperature sensors can be used for functions such as room or return-air temperature, evaporator defrost termination temperature, and evaporator outlet or suction-line temperature monitoring. Master-Bilt documentation identifies these as important sensing positions in its Master Controller refrigeration systems. Master-Bilt

For applications using 19-13968 as an evaporator inlet or outlet temperature sensor, install the replacement in the same position as the original probe. Sensor placement matters because moving the thermistor to another part of the refrigeration system can produce a different temperature reading.

10-Foot Cable for Commercial Refrigeration

The Master-Bilt 19-13968 configuration uses a 10-foot, or approximately 120-inch, cable. Multiple commercial refrigeration parts catalogs confirm the 10-foot length for this NTC thermistor assembly. Parts Town

The extended cable provides flexibility when routing the sensor from the evaporator or other sensing location back to the compatible controller. When installing the replacement, follow the original cable path whenever possible and keep the wiring protected from sharp edges, fan blades, excessive heat, and other areas that could damage the insulation.

Helps Restore Accurate Refrigeration Control

A damaged or inaccurate thermistor can send incorrect temperature information to the refrigeration controller. Depending on the equipment and sensor position, possible symptoms can include incorrect temperature readings, inconsistent refrigeration performance, abnormal compressor operation, defrost problems, sensor alarms, or unexpected refrigeration cycles.

Master-Bilt documentation states that its controller monitors the operating range of connected temperature sensors and can display an alarm if a sensor detects a temperature outside its expected range. Master-Bilt

These symptoms do not automatically mean the thermistor has failed. Similar problems may result from damaged wiring, loose connections, incorrect controller settings, airflow restrictions, evaporator fan problems, dirty condenser coils, refrigerant system issues, or another refrigeration component.

Proper diagnosis should be performed before replacing the sensor.

Tested for Reliable Performance

Commercial refrigeration sensors operate through repeated heating, cooling, defrost, and refrigeration cycles. Consistent electrical response is essential for dependable temperature monitoring.

Each Wholesale Sensors replacement for Master-Bilt 19-13968 is rigorously tested for temperature response, resistance characteristics, electrical continuity, sensing consistency, connection integrity, and reliable performance.

The sensor is designed to provide the temperature-dependent resistance signal expected by compatible Master-Bilt equipment while maintaining the 10-foot configuration required for the original installation.

Straightforward Replacement

Before servicing commercial refrigeration equipment, disconnect electrical power and follow the equipment manufacturer’s safety procedures. Locate the existing thermistor and document its mounting position, cable routing, and electrical connection before removing it.

Install the replacement sensor in the same sensing position and route the 10-foot cable according to the original configuration. If the probe is being used as an evaporator outlet or suction-line sensor, maintain secure thermal contact with the tubing according to the Master-Bilt service procedure.

Master-Bilt specifically notes that its outlet sensor should have good contact with the suction line and should be removed before brazing work is performed near the evaporator. Master-Bilt

Commercial refrigeration systems do not use automotive OBD-II diagnostic codes. If a sensor alarm or refrigeration problem remains after replacement, inspect the wiring, connections, controller, evaporator and condenser fans, airflow, refrigeration circuit, and related components.
