The legacy Sub-Zero 500 series includes models like the 501, 511, 532, 550, 561 and 590. These older built-ins use mechanical or simple electronic controls without fault codes. Common repairs are defrost timers and heaters, thermostats, fans, start components, compressors, gaskets and door hardware.
