Possible Causes
Blown internal fuse on PCB, Failed SMPS power supply components, Loose mains connector, Shorted component drawing down supply
How to Fix / Troubleshooting
Safety first: Unplug the air fryer. Internal capacitors can retain charge; if you are not experienced with electronics, seek professional service.
- Check mains lead and plug: Inspect the Morphy Richards power cord and plug for damage. Test the wall outlet with another appliance.
- Internal fuse: Remove the housing to access the main control PCB. Look for a small glass or ceramic fuse. Test continuity; if blown, replace with the same rating only after checking for shorts.
- Visual PCB inspection: Look for burnt components, bulging electrolytic capacitors, or cracked solder joints in the power supply section.
- Component‑level repair: Replacing individual SMPS components (diodes, regulators, capacitors) requires electronics skills. In most home repairs, replacing the entire main control PCB is more practical.
