All of a sudden, my KitchenAid KHMS2050SSS-0 microwave hood decided to heat much less than normal. Everything else still appears to be working, but the heat is about 50% less than usual. It also became very quiet when heating, perhaps the fan is not working? Earlier there was this normal whooshing sound when cooking, but now it's quiet, I can only hear some faint noise from the turntable spinning.
Does someone have an idea what is wrong and what do I need to replace to get it back working properly?

Thanks.
