Plastic housing or handle becomes excessively hot to touch during use.

Safety first: If the exterior becomes dangerously hot, unplug the unit and discontinue use until inspected.

Steps to reduce exterior temperature:

• Check ventilation: Ensure all vents are clear and the unit has sufficient space around it.
• Inspect fan operation: Confirm that the convection fan motor runs at full speed; a failing fan can cause heat buildup.
• Open housing: Inspect internal heat shields and reflective liners for displacement or damage.
• Replace shields: If heat shields are missing or warped, replace them with original Princess parts. If the fan is faulty, replace the convection fan motor.
