That's what happens with loose electric connections. Need to go from the breaker to the AC unit power run inspecting each wire splice, all electric connections need to be clean and tight.
A loose connection becomes electrical resistance and electrical resistance consumes power, power consumed is dissipated as heat. Overheated, charred, discolored connections can be cut off and reconnected when found.
Start by tightening the circuit breaker wires, and neutral if any.

Your Friedrich A/C should be connected to a dedicated 20-amp breaker with 12 gauge wire, at least. There should be nothing else connected.

I would contact the manufacturer or their agent.

Did you use the Reset button? Did you call (800) 541-6645 and ask Customer Service? Is the Air Conditioner plugged into a power strip? Is the reset on the power unit ON or OFF? If the unit is plugged into a wall AC outlet is the circuit breaker to that AC outlet in need of reset? Is there a foul odor?

Here's some things that could be causing your issue.
A clogged air filter could be one possible cause.
However I suspect the units high limit switch is the culprit.
This is an image of a high limit switch for visual reference only.
