Ralph M Alto , TX December 19, 2018 Appliance: Model LG DLEX5170W No heat The hi limit thermostat p/n 693EL3003D was open (symptom), which I replaced . I also replaced the thermostat p/n 6931EL3001F (cause). This fixed my problem. Initially, I was apprehensive about removing the dryer drum, but it was very simple. This made access to parts in the dryer very easy. A simple problem to resolve. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
