Step 2: Clear Out Excess Oil and Food Debris
- Use a soft brush or non-abrasive sponge to scrub stubborn residues.
- Wipe the interior of the unit with a damp cloth, paying close attention to the heating element area.
- If needed, lightly spray with vinegar or a mild cleaning solution to dissolve grease spots.
Step 3: Inspect and Replace Liners Properly
Make sure you are not using liners during preheating or without enough food on top to prevent them from flying up and touching the heating element. If using disposable liners, choose ones designed for air fryers, and do not preheat with liners in the basket.
Step 4: Check for Overfilling and Oil Usage
- Avoid overfilling the basket, which can cause excess smoke from trapped grease or juices.
- Use minimal oil and evenly distribute it to prevent excessive smoke.
Step 5: Reassemble and Test
After cleaning and inspection, reassemble the air fryer. Run a short test cycle at a lower temperature (around 350°F) with no food to see if smoke persists. If smoke continues, further troubleshooting or professional repair may be necessary.
