After heating only one Lean Cuisine-style frozen meal, the High Pointe convection microwave in our 2015 Prism will overheat and shut down while heating the second meal. The interior metal is very hot to the touch. We are not using any prohibited dishes or materials in the oven. Any ideas why the oven would overheat so quickly? I cannot find any discussion of this in the manual.

Are you connected to power? Well I guess you'd have to be, no way that microwave would run off batteries.

I would suspect eh microwave itself has an issue. Where it me, I'd run the microwave from another power source. For instance, run a heavy gauge extension cord from your house into the rv and plug the MW into that, and see if it still overheats.

Or you could pull it, and take it inside and plug it in in your kitchen and see if it overheats.

If your microwave is not getting enough power from the RV, that would cause a problem right away, and it would get hot trying to pull the juice.

If the MW worked great on another power source, I'd then be testing the plug in my RV to see that full power is there and operational when a load is pulled. Microwaves pull a LOT of juice. It's all together possible that the wiring to the plug for the microwave is too small, and it's having a hard time supplying the right amount of electricity under load.

OR the MW itself could be bad. I'd want to separate the two to determine if the problem exists in the microwave itself or not.

High Point is a pretty low end rig and I have found the higher end units tend to contain heat much much better. That said , most have fans in the rear of the unit for cooling. Could pull the unit out, put it on a counter run it and see if the rear is exhausting heat like it should. Could b e just a bad fan, or may take you further down the rabbit hole into the unit.

Our High Point CO vents thru the wall outside. Have someone turn it on while you're outside and see if the unit is venting/fan is exhausting.
(Also make sure the little door outside isn't latched shut)
