Microwave displays F2 and may stop mid-cycle; keypad may still respond.

Safety first: Unplug the microwave. High temperatures may have occurred.

• Check ventilation: Ensure all vents are clear and the unit has proper clearance.
• Allow cooling: Let the microwave sit unplugged for 30–60 minutes, then test.
• Inspect thermostats:
  • Remove the outer cabinet.
  • Locate thermal cutouts/thermostats on the magnetron and cavity.
  • Check for signs of overheating or discoloration.

If F2 returns, a thermostat or sensor is likely faulty and should be replaced with the correct Black+Decker part. This repair is best done by a technician due to proximity to high-voltage components.
