Good To Know

Q: Will this RPM sensor work on my older Thermo King Whisper unit? A: This sensor is designed for Thermo King SLX, Whisper 400/300/200/50, and Spectrum 100 models; check your serial number to confirm exact compatibility.

Q: What causes an RPM sensor to fail? A: Exposure to moisture, vibration, or excessive heat can degrade the sensor over time, leading to erratic readings or engine shutdown. Replacing it restores reliable performance.
