Microwave interior light does not come on, but unit heats and operates normally.

Safety: Unplug the microwave before replacing the lamp. Some models require cabinet removal; others have an access panel.

Steps:

• 1. Locate lamp access: Check the user manual. Many Morphy Richards models have the lamp behind a small panel at the rear or side; others require removing the outer cover.
• 2. Remove old lamp: Carefully unscrew or pull out the lamp from its holder. Avoid twisting the glass excessively.
• 3. Install new lamp: Fit a Morphy Richards-compatible microwave cavity lamp of the same voltage and wattage. Do not substitute with non-microwave-rated bulbs.
• 4. Test: Reassemble, plug in, and open/close the door or start a short cook cycle to verify the lamp works.
