Safety: Unplug the unit and allow it to cool for at least 30 minutes before touching internal parts.

Steps:

Check environment: Ensure the room temperature is within Honeywell’s specified operating range (typically 41–95°F / 5–35°C). Do not operate in confined closets or near heat sources.
Clean filter and grilles: Remove and wash the air filter with mild soap and water. Vacuum dust from the intake and exhaust grilles.
Verify clearance: Provide at least 12–18 inches of clearance around all sides of the unit for proper airflow.
Inspect fan operation: With the cover removed (and power briefly applied if you are qualified), verify the fan spins freely and at full speed. If it is slow, noisy, or not starting, replace the fan motor assembly.
Check thermal sensor/fuse: Locate any thermal cutouts or high‑temp sensors near the compressor or discharge area. Test for continuity and replace if open (following Honeywell’s part specifications).

Warning: Do not bypass thermal fuses or safety sensors; this creates a fire hazard.

Dehumidifier shows E8 and shuts down; may be accompanied by unusually hot air discharge.
