Mr. Cool isn't procuding heat, can't identify the unit to even start diagnosing the issue.

This is the Mr. Cool in my apartment. recently, it doesn't get warm at all no matter how high I turn up the heat. It'll feel like its shooting out hot hair for a few minutes, then get cold. The filters seem to be clean, I don't know what else to check.
