Charger gets unusually hot to the touch during normal charging, even at rated current, but no error code is shown.

Burn and fire risk: If the housing is too hot to touch comfortably, stop using the charger until inspected.

• Step 1 – Improve airflow: Ensure the BougeRV charger has adequate clearance and is not enclosed in a small cabinet.
• Step 2 – Clean vents: Disconnect power and remove dust from vents with a vacuum or compressed air.
• Step 3 – Check fan operation: With the cover removed and power restored, observe the internal fan during charging. Replace the BougeRV internal cooling fan if it does not run smoothly.
• Step 4 – Tighten power connections: With power off, tighten all high-current terminals on the input and output sides. Loose connections generate heat.
• Step 5 – Thermal interface: If overheating persists, a technician may need to remove the power module, clean old thermal compound, and apply new high-quality thermal paste between the module and heatsink.
