Plug gets hot on air fryer

[signcrafter]

We just bought a house and are in the process of moving 2 hours to different a different state. At the new house built in the 70s there are 4 duplex outlets on 2 circuits. I doubt this is original and guessing someone added or modified them at some point. They are on 20 amp breakers but have not dug into them yet to figure out what size wire they are. But we bought a new ninja air fryer and whenever we use it on either circuit the plug gets pretty hot and the rubber is very pliable. Thinking something isnt right here either with the air fryer or the outlets. Planning on digging into this over the weekend but wanted to see what other more knowledgeable people would suggest? I plan on trying the fryer on another circuit and also pulling the outlet apart to see what size wire it is. Make sure someone didnt just add a 20 amp breaker to 14 gauge circuit. Should I get an amp clamp to see how many amps its pulling? Anything else to look for?

is the receptacle you're plugging in to a solid fit? try it on another outlet & see if you get the same results.
you also could have a bad cord ( wire poorly crimped)

Looking online, it look like the Ninja Air Fryer can pull up to 1800 watts depending on model, which is about 15A of current. 15 A sustained will make pretty much any standard outlet get rather warm.

he's talking about the plug on the cord getting warm and soft not the outlet

sounds like the tangs in the receptacle may be loose as @The Cobbler alluded too... how hard is it to push the plug into the receptacle?

Just as a precaution I would replace those receptacles with premium grade ones.

If the budget allows, Hubble is my wiring device of choice.

A sustained 15A will make just about any plug/cord warm with sustained use. Especially on a kitchen appliance that almost certainly has a wimpy 14 gauge cord with PVC jacket.

But I mean, hot is also relative. If it's 100 degrees warm, it's pretty normal (IMO) given the power. If it's 140 degrees, that's a different story.

Hubble makes excellent Plugs as well as receptacles.

They tend to be on the "Pricey" side.

This will identify if it's the cord or the receptacle. The cord may be normally warm but not hot. If it's too hot to hold continuously I would say that's too hot for a cord. If the receptacle grips the prongs tightly is the wiring to it back stabbed?

P=EI

At 1690W you get 14A

Which one is it, 14A or 15A?

P = EI cos(theta) for anything but DC and purely resistive circuits.
but I would expect the main load to be heaters which are unity power factor. Still could be enough to make 1 amp of difference.
