6. Troubleshooting

If you encounter issues with your COOLHOOD thermometer and hygrometer, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
Inaccurate Temperature Reading	Direct sunlight exposure. Proximity to heat/cold sources (e.g., vents, windows). Strong drafts.	Relocate the thermometer to a shaded area. Move away from direct heat or cold sources. Place in an area with stable air flow.
Inaccurate Humidity Reading	High moisture environment (e.g., bathroom). Extremely dry environment. Device not given enough time to acclimate.	Ensure placement in a general living area. Allow 15-30 minutes for the device to stabilize after relocation.
Physical Damage	Dropped or impacted.	Discontinue use and consider replacement. Mechanical damage can permanently affect accuracy.
