Air fryer plug and electrics question

Yes it’s 2400 watss

I just checked the 13A plug for our conventional fan oven, ( also around 2.5KW) after it had been switched on for 20 mins. Maybe there was a slight warmth in the cable near the plug, but the plug itself was cold.
With the kettle then cable near the pug was a bit warm, but plus was cold to touch.

Pretty much what I'd expect from a well-made appliance.  There's less thermal insulation and closer contact between conductors as they go through the strain relief.

I wouldn't expect a plugtop to remain cold with a substantial load drawn through it for a reasonable amount of time. The question really is whether it's running warm or hot.

If the socket is old, the spring connectors that touch the pins on the plug can get tarnished and slack, both of which could increase the heat produced at the plug pins.  Therefore changing the socket faceplate for a shiny new one *might* help

Thank you. I have tried it in  4 plug sockets and it does the same in all of them.

then the problem is obviously with the plug as unless the air fryer is some dodgy import, there is no way the plug should be getting hot during normal operation as it must be rated for 13amp max otherwise the fryer would not have a "normal" 3 pin plug.

Try using the lead off your kettle (assuming you have a "old fashioned" kettle with detachable lead)). Most air fryers use standard "kettle" sockets for the lead to connect to, with a 3 pin plug for the wall socket, so are perfectly interchangeable with (13 amp) kettle leads.

I have 3 airfryers and none of them use a kettle lead.  I've never check how hot the plugs get but laptop chargers get quite hot and I thought that was normal.

I s'pose ovens only draw current for a fraction of the time once they're up to temperature.  Kettles get away with increasingly thin flex since they're only on for a few minutes.   Don't know what kind of duty-cycle airfryers run

I have a similar issue with a fan heater.  When heating a room when other heating is off the plug gets too hot to touch at the pins when using around 2k.  The plug is moulded.  Would it be best for me to fit my own plug which I have spares of and have fitted my own many times a long time ago so feel confident I can do it correctly?

Changing the plug would void the warranty of many items (that becomes an issue sometimes for kitchen appliances when people cut the plug off to feed the cable through a cupboard), but apart from that there is no problem with you competently changing to another plug with an appropriate rating and fuse.

Laptop chargers get warm because they're converting mains supply 230 V AC down to low voltage DC. The heat is due to wasted energy as the conversion is never 100% efficient. A cable on a mains voltage appliance like a kettle or air fryer is quite different. It's just a passive piece of metal, and will get a little bit warm if a very high current flows through it, but the situations are quite different.
