Good To Know
Q: Will this 40-974 sensor work on a Thermo King SLX100 with a different serial number? A: The 40-974 is a graded sensor designed for the SLX100 family, but confirm your unit's serial number and current sensor part before ordering to ensure a match.
Q: What happens if the air temperature sensor fails? A: A failed sensor can cause inaccurate temperature readings or unit shutdown. Replacing it with the 40-974 graded sensor restores reliable performance.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
