Old post but on my last trip tried to use my Highpoint in the convection mode to cook a pizza on my 2017 Vegas. It would heat up to about 350 then there is a click and the heating element shuts off and it cools down to about 200 then restarts.
Also on microwaving a large frozen dish 20 minutes thru it turns off the magnetron until it cools down then it turns back on and goes again.
In both situations the lights fan Etc continue to function.
On a bet I pulled it out of the cabnet about 4 inches and found it to be blazingly hot. There is no venting of the heat in that confined enclosure. Im going to mount some 12volt muffin fans (type used on computers) to force some cooling
