DIY refrigerator repair instructions can be found online at The Family Handyman and video tutorials can be viewed on YouTube. Libraries also carry books with repair instructions.
Before starting a repair, the owner needs to be familiar with the anatomy of the appliance and take all safety precautions. Reading several DIY guides and watching a few videos can help determine if the repair can be done safely without the assistance of a licensed repair technician.
A nut driver, an adjustable wrench, a 4-in-1 screwdriver and a level are the usual tools required for refrigerator repairs. A vacuum, hair dryer, and long brush are also essential to avoid frustration and save time.
