Safety: Do not attempt live electrical testing unless you are trained. Always unplug before inspecting internal wiring.

Steps:

Check household power: Test the outlet with another appliance or a plug-in tester. Reset any tripped breakers or GFCI outlets.
Inspect power cord: Look for cuts, burns, or crushed sections. If damaged, the cord must be replaced by a qualified technician.
Try another outlet: Plug the cooler into a different known-good outlet (no extension cords) to rule out outlet issues.
Internal fuse: Some Frigidaire models have an internal fuse on the control board. With power disconnected, remove the control cover and visually inspect the fuse. Replace only with the same rating if blown.
Control board replacement: If the fuse is good and power is present at the board input but the unit remains dead, the main control board power supply is likely failed and should be replaced.
