Unit will not turn on at all; no lights or display when plugged in.

Safety: Before opening the unit, unplug it. If you suspect a wiring or breaker issue, turn off power at the panel.

Steps:

• 1. Check outlet and breaker: Test the outlet with another device. Reset any tripped breakers or replace blown fuses in the home panel.
• 2. Inspect power cord: Look for cuts, burns, or loose connections at the plug. Replace the cord if damaged.
• 3. Internal fuse: Remove the front panel and locate the main control board. Many Frigidaire boards have a small glass or blade fuse. Test with a multimeter and replace with the same type and rating if blown.
• 4. Control board: If power is present at the board but there is no display or response, the main PCB is likely defective and should be replaced.

Warning: Do not bypass fuses or safety devices. If a new fuse blows immediately, there is a short that requires professional diagnosis.
