I'm pretty sure if they were Alarmed by the temperature it was too hot for purpose

they also said

I don't care what they said, they're not experts, a lot of people still think WiFi/5G gives you cancer - none of these people know the first thing about the subject.

Its perfectly possible the reason it got so hot was because you had it in the wrong orientation as its designed to go on the ceiling and they usually have a bracket holding it there so its not actually touching the ceiling.

Like I said before, LED lights that go on the ceiling have the heatsink at the back against the ceiling and are too hot to touch in use.  In ceiling halogen lights get even hotter, its literally the same heat output as an electric hob, you wouldn't even get close to touching that.  Electrical fires are started by actual sparks, arcing due to bad connections.  Hot electrical wiring is only a problem if its hot enough to melt the insulation, and then the problem is due to being able to pass enough current to cause arcing and start a fire.

If its not hot enough to soften the plastic, its definitely not hot enough to set the ceiling on fire.  Have you never felt surfaces after they've had direct sunlight on them?  Or a plastic kettle even?

I tested it face down so the air could get at the back & so did they

In summation no one else has an over heating WAP, I sent the device back & the supplier agreed it was alarmingly hot

I'll decide this weekend what I will replace it with. It'll be another TP-Link & the supplier said they would test it for heat this time

I'll post further info

cheers  :)

More likely nobody else checked or they assumed it was normal, which it probably is.

I would be curious to know if they checked others of the same model to see if they do the same.

Its not impossible its faulty, but I'd still argue its unlikely to be a fire risk as if it got that hot it would melt something on the PCB and die at much lower temperatures than a halogen light bulb reaches, all happening isolated in the case which is likely self extinguishing to avoid fire.

Quote
On average, a halogen bulb can reach temperatures of around 250 to 500 degrees Celsius during normal operation. This level of heat can be significant, especially considering that traditional incandescent bulbs typically reach temperatures of around 150 to 200 degrees Celsius

A voltage regulator for example will either fry or shut off at around 135C.  Other components would fail at even lower temperatures.

A device will start to feel "too hot to the touch" at around 40C by comparison, and feel "alarmingly hot" at 50C.  Yet a lot of laptops will run their CPU at 95C, my gaming laptop by this measure will get "alarmingly hot" under heavy use as even with the fans flat out the surface temperature gets too hot to touch.

As I understand it the legal requirement is that its not allowed to get so hot you will burn your finger before you have a chance to remove it, but things being mounted to a ceiling do not necessarily have this requirement as you're not supposed to touch them in operation.

Dude, if your laptop is hitting 95C it's in trouble

If it's the CPU turn the Turbo off in the BIOS

Take the back of the laptop, clean the airways & apply new thermal paste like I said

High-end laptops ALL hit those kinds of temperatures - they are designed to hit the thermal throttling limit of the CPU.  Many modern desktop CPUs adopted the same strategy.

For you heat from your devices is not a problem, I think the opposite

I don't want any problems; fire or malfunction

Personal preferences differ

I'm just shocked you've never run into this "issue" before.

I've been using NiMH batteries for decades and they get too hot to touch right after charging.  Every time you reply I think of another example, its so common.
