iGrow 100 Series Sensor Troubleshooting

Temperature sensor is fluctuating or not registering at all

Check sensor connection wires on the controller make sure there snug & tight.

Check connection’s inside junction box (if one exists) for moisture or corrosion

Check the PCB for corrosion, moisture or contamination build

Check the line that leads to that box for cuts or any damage which will affect the sensors readings.

Check for wire any interference sources (voltage, motors, inverters, etc….)

Cycle equipment ON and OFF and see if Sensor Reading appears or Stabilizes

Check the power supply P/S and see if dropdown voltage AC to 12VDC is accurate.
- Since incorrect voltage can discourage the logic within the device.

Try powering iGrow from a different circuit entirely (extension cord across the way or an inverter) and see if the sensor stabilizes.
