My electric heater (the kind that blows out air) is acting strange - it's heating for maybe 10 seconds, then there's an audible click and a flash of light from inside the grill, then it start pushing out cool air; wait 10 more seconds and it starts blowing out hot air again.
So, a) what causes this, and b) can I do something about this with basic tools?
Yes a new one's cheap but it's more of a /diy/ principle, I'd rather try to fix something first before replacing it.

It is a safety feature. Make sure the fan is upright. There should be a switch that turns the off if tipped over so you don't catch your house on fire. Does it completely shut off?

its probably the high limit switch that you hear clicking and breaking the circuit. thats usually due to low airflow either from it being dirty or the inlet/outlet being blocked in some way

It's obviously standing upright on its feet, so it must be something else. Also there's no switch in this one, its short legs keep it off the floor. It's more like pic related than the OP.
its overheating, mine did the same thing.
Either the fan isnt kicking the air it should be and cooling it enough or the wire coils have a short.
Fan is easy to do, put a drop or 2 of oil on the sleeves of the motor making sure you just get enough on it to lube the shaft and not splash it onto the coils you should get a little more life out of it.
If the coils have a short just toss that shit right out. Mine had a short in the coils and I kinda bandaided it... then it caught on fire.

I see that this is three hours old, but just wanted to point out that on a cheap Chinese heater like this, a short wouldn't reset itself.
A hilimit acting as a thermostat would. It heats, satisfies while airflow is low, then cools, and turns back on. Although, it's probably meant for safety.
The hilimit is probably covered in shit, causing the contacting surfaces to be closer together than normal, causing a spark.
If it's new, it's probably metal flakes from shitty Chinese children's manufacturing.
I have a love-hate relationship with these little fucks. I use them in a dusty workshop every winter. Every year one of them breaks and I take it apart, clean it and/or replace burnt wiring and keep using it until it dies completely or catches on fire. Every new replacement over the years gets harder to crack open to maintain, shittier, and more expensive. And yet, I almost look forward to spending 2 hours every winter fucking with one. There's something beautiful about the electrical gore to me, and the challenge of fixing something not worth fixing.

Why not just buy yourself a good salamander and be done with it?
