Morphy Richards oven heats but does not reach the set temperature; food takes significantly longer to cook.

Safety first: Disconnect the power supply before testing any components.

Steps:

• Verify with thermometer: Use an independent oven thermometer to compare the actual temperature inside the oven with the set value.
• Inspect elements: Look for cold spots or an uneven glow on the heating elements. Replace any main oven elements that are visibly damaged or show readings outside of specifications.
• Check door seal: Inspect the oven door gasket for any gaps, tears, or signs of compression. Replace it if it does not seal evenly.
• Test sensor: Measure the resistance of the temperature sensor at room temperature and at a known elevated temperature (e.g., 100°C in boiling water, if the sensor is removable). Replace it if the readings are outside the specified range.
• Calibration: Some Morphy Richards models allow for temperature offset adjustment within the settings menu. Adjust this setting according to the user manual if all hardware components are found to be sound.
