Description

Overview

Thermo King RPM Sensor suits selected SB, SL, SLXi and T-Series units and feeds engine speed input to the controller. When that signal drops out, the unit can log engine RPM alarms, lose stable speed feedback or behave erratically during diesel operation, so replacing the sensor makes sense during electrical fault work.

Features

• Suits selected Thermo King SB, SL, SLXi and T-Series applications
• Provides engine RPM input for control and alarm handling
• Relevant when the unit logs Check Engine RPM faults or shows unstable speed feedback
• Replacement sensor for reefer electrical diagnosis and repair

Specifications and Materials

Thermo King RPM Sensor is a direct replacement style engine speed sensor for selected refrigeration units. Match the unit family and fitted sensor before ordering, because sensor layouts can vary across older fleets and previous repairs can change what is already in place.

Part number: TK-44-9298-AM.

Compatibility and Fitment

Check the unit family and fitted sensor before ordering. This part suits selected Thermo King SB, SL, SLXi and T-Series applications. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. 44-9298, 449298, 449-298, 1189A70G03

Compliance and Safety

Disconnect power before removing the old sensor, then keep the connector area clean during refit. If the harness shows oil, dirt or damaged insulation, inspect that at the same time because a new sensor will not correct a poor connection on its own.

Trailer Applications

Thermo King RPM Sensor suits workshop repairs where the controller needs a steady engine speed signal for normal diesel operation. It is most relevant when technicians chase intermittent RPM alarms, missing speed input faults or shutdown complaints linked to engine speed feedback.
