Refrigerator repair guides are available from specialty online retailers such as Repair Clinic and informational websites such as Appliance Repairs. Manufacturers generally do not offer repair manuals for their products, though simple repair methods are often included in the owners manual.
Appliance Repairs features an eight-chapter online repair manual that begins by explaining the basics of a refrigeration system. The manual goes on to discuss more complicated repair procedures, including testing the voltage, repairing or replacing faulty wiring, and testing the compressor. Other online retailers sell do-it-yourself refrigerator repair manuals for a variety of manufacturers. As of February 2015, a repair manual for Whirlpool-built refrigerators costs $25 on Repair Clinic.
