I wouldn't think so, unless the ice melted and water got in/on something that doesn't like it...Pull the code and post it here.

Its not low on freon, it is your ac sensor on the high pressure side. the ac system is supposed to cycle if it doesn't cycle it will freeze up like your system is. Low freon would cause no or very little cooling or frost. Your system is just staying on and not cycling on and off causing it to freeze up
