Those who opt for an LG smart range will enjoy Smart Diagnosis, a preventative and reactive feature on LG models that works to curtail and troubleshoot problems. The range will perform a check and send the results via WiFi to a technician. The diagnosis will then be sent back to you, along with the appropriate next steps to follow. In most cases, this saves you time and the potential cost of an in-person maintenance visit. The diagnosis can be sent via text, or you can opt to have an audible, recorded diagnosis to listen to and follow.
