If your Morphy Richards microwave is running but not heating food, this can be frustrating — but it’s often caused by settings, usage, or simple checks rather than a fault.
Follow the steps below to identify and resolve the issue.
1. Check the Power Level Setting
If the microwave is set to a low power level, it may appear to run without heating effectively.
- Ensure the power level is set correctly (e.g. High/100%)
- Re-select your programme and try again
Some models require you to manually select the power level before starting.
2. Check You Are Using Microwave-Safe Containers
Using the wrong container is one of the most common reasons a microwave appears to run without heating properly.
- Only use microwave-safe containers
- Avoid metal, foil, or items with metallic trim
Important:
Some containers labelled “microwave safe” (such as takeaway containers or low-grade plastics) may not heat food effectively.
These containers can:
- Absorb heat instead of transferring it to food
- Remain cool while the food heats unevenly or very slowly
✅ For best results, use:
- Glass containers
- High-quality microwave-safe plastic
- Ceramic (without metallic decoration)
❌ Avoid:
- Takeaway containers
- Thin or low-grade plastics
- Containers not specifically designed for microwave use
Tip: If in doubt, try heating food in a glass container to see if performance improves.
3. Ensure the Door Is Fully Closed
Microwaves will not heat if the door is not properly shut, even if the display and timer are running.
- Open and close the door firmly
- Check for debris around the seal
- Ensure the door clicks securely into place
4. Check the Turntable and Food Positioning
Uneven placement can affect how food heats.
- Ensure the turntable is fitted correctly and rotating freely
- Place food centrally on the turntable
- Avoid overcrowding the microwave
5. Try a Simple Heating Test
To confirm whether the microwave is heating:
- Place a cup of water inside
- Heat on full power for 1 minute
If the water does not heat, this may indicate a deeper issue.
6. Check for Child Lock or Incorrect Settings
Some models may appear to run but not operate correctly if settings are incorrect.
- Check that no lock function is active
- Restart the cooking programme from the beginning
