42-1307 Pressure Sensor for Thermo King | Aftermarket Replacement
42-1307 Pressure Sensor for Thermo King monitors refrigerant pressure in the refrigeration system and provides pressure information to the control system. It is an aftermarket replacement option for selected Thermo King transport refrigeration units.
Product Description
The 42-1307 Pressure Sensor is a replacement pressure transducer for selected Thermo King transport refrigeration equipment.
The sensor measures system pressure and sends a corresponding signal to the refrigeration unit control system. Accurate pressure information helps the system monitor operating conditions and manage refrigeration performance.
The 42-1307 appears in Thermo King aftermarket parts catalogs as a Pressure Sensor / Pressure Transducer. Some parts suppliers also cross-reference it with 42-2282 and other related pressure transducer numbers.
Because Thermo King uses different pressure sensors for different refrigeration systems, customers should confirm the original part number, unit model, and sensor application before ordering.

Main Function
The pressure sensor provides important pressure data for the refrigeration system.
It helps the system:
- Monitor refrigerant pressure.
- Send pressure information to the controller.
- Detect abnormal pressure conditions.
- Support stable refrigeration operation.
- Assist technicians in diagnosing refrigeration system problems.
A faulty pressure sensor can provide inaccurate pressure information. This may lead to warning messages, incorrect system control, or refrigeration performance problems.
Common Replacement Symptoms
A damaged or failing pressure sensor may cause:
- Incorrect pressure readings.
- Unstable pressure signals.
- Pressure-related alarm messages.
- Abnormal refrigeration operation.
- Difficulties during system diagnosis.
- Intermittent sensor signals.
These symptoms can also result from wiring, connectors, refrigerant, or other system components. Technicians should inspect the complete circuit before replacing the sensor.
Related and Cross-Reference Part Numbers
Several Thermo King pressure transducer numbers appear in aftermarket catalogs alongside 42-1307.
| Part Number | Description | Notes |
|---|---|---|
| 42-1307 | Pressure Sensor / Transducer | Main product number |
| 42-2282 | Pressure Transducer | Frequently cross-referenced with 42-1307 |
| 42-1312 | Pressure Transducer | Listed as a 500 PSIG discharge transducer |
| 42-2827 | Pressure Transducer | Listed as a related replacement number |
The relationship between these part numbers can depend on the equipment application. For example, aftermarket sources identify 42-2282 as a replacement for 42-1307 on selected SB units, while other suppliers list 42-1312 as a replacement for 42-1307 and 42-2282 for selected SLX/SLXe applications. Therefore, customers should verify the unit model and original part number before treating these numbers as interchangeable.
42-1307 vs. 42-2282
The numbers 42-1307 and 42-2282 are commonly associated with the same pressure sensor replacement application in aftermarket catalogs.
For selected Thermo King SB units, suppliers list 42-2282 / 42-1307 together and identify them as replacement pressure sensor numbers.
However, customers should still compare the original part number and equipment model before ordering.
