Product Overview
This solenoid controls the engine fuel shutoff on compatible Thermo King systems. A unit that cranks but does not stay running or an engine that fails to stop can have a solenoid/control issue, though wiring, relay output and the mechanical fuel lever should be checked first.
42-0100 has broad historical Thermo King coverage including KD-II, MD-II, RD-II, multiple MD/TS/SL families and other units depending on production date. Cross-reference data also shows several earlier Thermo King and Woodward numbers.
Later units may use a different shutdown actuator, and some service information identifies production-date changes. Verify the unit model, serial and original solenoid before ordering.
