E5 error appears and the air fryer shuts off shortly after starting.

Safety first: Unplug the unit. Over‑current faults can indicate a serious electrical problem. Do not continue to reset and run the unit until inspected.

• Step 1 – Visual inspection: Remove the basket and pan. Look up at the heating element area for signs of arcing, burn marks, or heavy carbonized grease. Clean gently if only surface grease is present.
• Step 2 – Check heater resistance: With the cover removed and unit unplugged, disconnect the heater leads from the main PCB. Measure resistance across the heating element. A typical value is between 10–40Ω. If it reads near 0Ω (short) or shows visible damage, replace the heater assembly.
• Step 3 – Inspect wiring: Follow the heater wires from the element to the PCB. Look for melted insulation or contact with sharp metal edges. Repair or replace damaged harnesses.
• Step 4 – Evaluate control board: If the heater tests normal, the triac or relay on the main PCB may be shorted. Check for burnt spots or cracked solder joints. Replace the main control board if defective.
• Do not bypass fuses: Never bypass internal fuses or safety devices to clear E5.
