Microwave stops heating shortly after start; display may show E02 and cooking time cancels.

Safety first: Unplug the microwave. Internal components can store dangerous voltage. Do not touch the high-voltage section.

External airflow checks:

• Ensure the microwave has adequate clearance on all sides as specified in the Candy manual (typically 10 cm or more at sides/top/back).
• Inspect rear and side vents for dust, grease, or obstructions. Clean gently with a soft brush and vacuum.
• Verify that the unit is not installed inside a closed cabinet without proper ventilation.

Internal cooling fan check (for experienced users):

• Remove the outer cover after unplugging the unit.
• Locate the cooling fan near the magnetron and transformer.
• Spin the fan blades gently by hand; they should rotate freely without scraping.
• If the fan is seized, noisy, or not running during operation (observe briefly with cover loosely in place, then unplug again), the fan motor is likely faulty and should be replaced.
• Inspect the thermal cut-out (thermostat) mounted on or near the magnetron for signs of overheating or loose wiring.

After cleaning and checks: Reassemble the cover fully, restore power, and test with a cup of water for 1–2 minutes. If E02 reappears quickly, discontinue use and arrange professional service, as prolonged overheating can damage the magnetron and cavity.
