E5 appears on the display and the air fryer stops heating or shuts off mid‑cycle.

Safety first: Unplug the air fryer before inspecting the cord or internal wiring. Do not operate with exposed wiring.

Steps to troubleshoot E5:

• Check outlet and cord: Plug another appliance into the same outlet to confirm proper voltage. Inspect the Pro Breeze power cord for cuts, kinks, or burn marks. If damaged, replace the entire cord set.
• Inspect cord entry: Remove the bottom cover to access the cord entry and strain relief. Ensure the cord is firmly clamped and the live/neutral connections are tight on the terminal block or PCB.
• Check heater terminals: Locate the heating element terminals. Look for discoloration, melted connectors, or loose spade terminals. Tighten or replace terminals as needed.
• Relay inspection: On the main control PCB, identify the heater relay (usually a small rectangular component). Look for burn marks or cracked solder joints. Resolder any cracked joints if you are experienced with electronics.
• Test continuity: With power disconnected, test continuity from the relay output to the heater terminals. An open circuit may indicate a broken wire or failed relay.
• Replace faulty parts: Replace a burned relay or damaged wiring harness with compatible Pro Breeze parts. If you are not comfortable working with mains voltage circuits, contact a qualified technician.

Warning: Incorrect wiring or relay replacement can cause electric shock or fire. If unsure, do not attempt board‑level repairs.
