Why is there frost on the coils of my Honeywell DH70W?
- JJustin WrightSep 9, 2025
If you see frost on the coils of your Honeywell dehumidifier, especially after recently turning it on in low room temperatures (usually below 41°F (5°C)), this is normal. The frost should disappear within an hour or so after the dehumidifier is switched off.
