My dryer won't start during dryer mode. It is a pretty basic dryer. It usually runs and heats during dry mode, but it has stopped. The timer runs all during the cycle, but the only time the motor runs, and the drum actually turns, is during "finish guard" mode, which is an intermittent cycle that just tumbles the clothes for a brief period after the dry cycle has completed. I have checked the thermostats, and have continuity on all but one, which is called the "cycling thermostat", and has four terminals with two red wires and two purple ones. What does this thermostat do? Should I have continuity between the reds, and continuity between the purples. Haven't gotten to the igniters and flame sensors yet. Maybe this weekend.

Model number listed on the dryer is LGC6848AQ1. Thanks for the response.
