Air fryer does not power on at all; no lights or display when plugged in.

Safety: Unplug the air fryer before any inspection. Mains voltage is hazardous.

Steps to diagnose no-power condition:

• Check outlet: Test the wall outlet with another appliance. Reset any tripped breaker or GFCI.
• Inspect power cord: Look for cuts, frays, or burn marks. Gently flex the cord near the plug and unit; if power flickers, the cord is damaged and must be replaced.
• Open the base: With the unit unplugged, remove the bottom cover to access the control PCB and power entry point.
• Locate and test internal fuse: Many Farberware models have a small glass or ceramic fuse on the control board. Remove and test with a multimeter for continuity. Replace only with the same rating if blown.
• Check thermal fuse in power path: Some designs route power through a thermal fuse near the heater. Test for continuity; replace if open.
• Inspect power supply section: Look for burned components or bulging capacitors on the control PCB. If present, replace the entire main control board.

Warning: Do not bypass fuses or safety devices. If fuses blow repeatedly, there is an underlying short that must be corrected.
