Safety: Before opening the unit, unplug it. If you suspect an electrical short, do not repeatedly reset breakers.

Steps:

Check outlet and breaker: Test the outlet with another appliance or a plug-in tester. Reset any tripped GFCI or breaker.
Inspect power cord: Look for cuts, burns, or crushed sections. If damaged, the cord must be replaced by a qualified technician.
Access main control board: Remove the rear or top service panel to expose the board. Look for an onboard fuse (glass or blade type).
Test and replace fuse: With the unit unplugged, check the fuse for continuity. If blown, replace with the same type and rating. If it blows again immediately, there is a short that requires professional diagnosis.
Inspect board for damage: Burnt areas or bulging capacitors indicate a failed board. Replace the main control board with an EdgeStar-compatible part.

Warning: If you are not comfortable working around mains voltage, contact a professional technician.
