If the MOT19481 receives 230V but fails to spin

Using a longer probe may interfere with internal components or place the sensor too close to the heat source

It effectively replaces legacy part numbers EM212 and 319143-228

The sampling tube must extend at least 5/8 to 2/3 across the HVAC duct width

Built for precision in R-410A refrigerant applications
