Objekt: Ovn. hjælp

Hej alle.

Jeg har en ovn der har simple formål.
Strømmen skal kunne tændes og slukkes, det samme med varmen og temperaturen skal være mellem 0 og 475 Fahrenheit.

Til sidst i min kode har jeg så lavet et scenarie.

Jeg har dog problemer med alle mine methods, da den melder fejl på samtlige.
Nogle der kan hjælpe mig med at gennemskue problemet og hjælpe mig til at få koden til at virke korrekt?

Med venlig hilsen Michael
