wall Air Conditioner problem. Smells bad on fan setting. Please help?

Question

I have a frigidaire 2.1v 12,000 BTU thru-the-wall a/c. The smell is not there on the cool setting, but when the fan setting kicks in it smells very bad, like a chemical smell. A repairman came and said it's not freon, it must be mold & mildew and took it for cleaning. He brought it back and it still has the bad smell. The smell is like a chemical or paint smell, something weird. What should I do please help

i mean 220 volt
