Hoover oven overheats and burns food even at low temperature settings.

Safety first: Turn off the oven at the mains immediately if it is overheating. Allow it to cool fully before inspection.

• Check temperature control:
  • On mechanical thermostat models, test continuity across the thermostat at room temperature with the knob in the OFF position; there should be no continuity.
  • If continuity is present when OFF, the thermostat is stuck closed and must be replaced.
• Test sensor on electronic models:
  • Measure NTC resistance at room temperature and compare to Hoover specifications.
  • If the sensor reads very low resistance (shorted), replace it.
• Inspect wiring:
  • Ensure the thermostat or sensor is wired correctly according to the wiring diagram.
• If control components are OK: The main control board may be driving the elements continuously; replacement by a technician is recommended.
