How to fix no display on my ICM Controls Thermostat?
- RRebecca DouglasAug 14, 2025
If your ICM Controls Thermostat display is blank, here's what to check: * **For hardwired installations:** Ensure that there is 24 VAC present at the thermostat. The display will be blank if there is no 24 VAC. * **For battery installations:** Make sure the batteries are not drained and are installed correctly. A blank display indicates drained or incorrectly installed batteries.
