Evidence strength: Strong
When to stop
If the appliance shows smoke, sparking, a burning or gas odor, electrical shock, active flooding, or another urgent safety sign, stop using it and seek appropriate professional help. Do not bypass safety devices to continue troubleshooting.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
