• Wiring cable from moisture sensor to PLC unit may not have the shield grounded properly. • VFD noise is creating a variable signal and wires from sensor need to be pulled out of wiring harness and run separately from voltage wires. • Build-up on moisture sensor, clean off sensor. • Sensor does not read proper temperature and cannot be adjusted to read proper temperature. The thermistor or thermocouple is damaged and sensor needs to be replaced.
