Hi @d544
Not sure if this [https://legalectric.org/f/2011/03/carrier-9200-weathermaker-uhe-om58-67.pdf|information] is relevant to your particular model variant (58MCA and 58MXA) but check if there is a LED fault code display on the control board or if not if there is any obvious component damage on the board at all. (see p.9-10 on the document linked).
What is the full model number of the unit? Perhaps check if there is a product info label on the unit somewhere (on the back?) rather than the brand/model name on the front.
Knowing the correct model number will help to find the correct spare parts if there is a faulty part that needs replacing.
