Depending on the problem, owners can fix many appliances without professional help. Repair websites such as AcmeHowTo.com offer repair guides for most appliances. A majority of these guides contain a section that allows owners to diagnose a problem, as well as step-by-step instructions on how to repair the appliance.
Repair websites are typically divided into small and large appliances. Small appliances commonly consist of two or three elements and are easier to repair. Large appliances are typically harder to diagnose and repair due to the number of components.
The manufacturer sells most replacement parts, as should local hardware stores. It is generally considered a better option to replace malfunctioning parts than to attempt to repair them.
