Temperature Sensor Orientation
and Failures
• Temperature Sensor failure will cause
following problems
1. Sensor fails and reads 97F at evaporator return will lead to
refrigerant flood back, incomplete defrost cycles.
2. Sensor fails and reads -40F at evaporator return will starve
evaporator
3. Sensor fails and reads -40F at evaporator inlet will lead to
refrigerant flood back.
4. Sensor fails and reads 97F at evaporator inlet will starve
evaporator
5. Both sensors fail will cause machine to shut down and
displays hot product shut down
