The High Limit Thermostat is an OEM part for LG dryers, designed to act as a critical safety feature within the appliance. This thermostat monitors the dryer's internal temperature, shutting off the heat source if it detects temperatures that are dangerously high. By doing so, it prevents overheating, which can lead to appliance damage or, in worst-case scenarios, fires. The high limit thermostat is a crucial component for the safe operation of your dryer, ensuring it operates within the specified temperature range. Causes of a faulty High Limit Thermostat can include a malfunction within the thermostat itself, such as a failure to accurately detect temperature changes, or issues with the dryer that cause it to run hotter than designed, such as restricted airflow or a malfunctioning heating element. Symptoms of a malfunctioning High Limit Thermostat include: The dryer not heating properly or at all The dryer repeatedly shutting off during cycles Excessive heat emanating from the dryer, indicating it is not regulating temperature correctly This OEM LG part is also compatible with some Kenmore models.Part Number AGM30045804 (AP7206815) replaces 6931EL3004B, 6931EL3002B, 6931EL3003F.
