The FFRA051WAE is a small, older window unit. At this age, problems usually involve the power cord safety device, the capacitor that helps the compressor start, or a fan motor that is wearing out.
A capacitor stores energy and should never be handled by owners. If the unit hums without starting, unplug it and book service. Frost on the front coil usually means low airflow from a dirty filter, or a room that is too cool for the unit to run efficiently.
