So based on the photo its 100% mold and once it takes a hold it is not safe to store food in it any longer as it could impact your health. The issue is even the smallest slightest bit of mold left after fridge is on it will just keep growing back and get worse it loves dark humid environments total breeding ground. I think the fridge needs to be thrown out because the Mold is in places you wont be able to access.
Did you just lose power? or did it get wet? its sounds like your having a mold problem and its internal where you cant get to it. Certain types of Mold will emit a foul stench. Really hard once it takes a grip.
If you are talking counter depth the Thermador is the way to go as they have the dual compressors. The ranges are pretty close but they do offer the 5 burner model. I think both are a better quality choice over the Jenn Air. If you are talking full height built in fridge they are similar but given the choices here I think Thermador is the best option.
Dacor built in refrigerators are built on their own platform and I think good quality overall, the DW ovens and cooktop are just ok but the fridges I dont have an issue with.
It is a good cooktop but nothing so special that wows me. I think many other brands will work just as well for less money. I think that Thermador makes a superior unit overall and would be a better choice , more features and a nicer appearance as well. If 36″ their freedom model is tops!
