The Thermal Limiter is an OEM part for Frigidaire dryers. It acts as a safety feature, designed to prevent the dryer from overheating by shutting down the appliance when the internal temperature exceeds safe limits.  Symptoms of a failing Thermal Limiter include: The dryer failing to start or stopping abruptly during a cycle No heat being generated while the dryer is running The dryer overheating or feeling excessively hot Common causes for a bad thermal limiter include restricted airflow due to a clogged lint filter or venting system, component failure from age or faulty manufacturing, and unusually high operating temperatures from overloading the dryer or mechanical failures elsewhere in the system. When a thermal limiter trips or fails, it must be replaced to restore functionality to the dryer. This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.This part fixes the following symptomsShuts off too soonToo hotTakes too long to dryWon't startNo heat or not enough heatPart Number 134120900 (AP2108182) replaces 146062-0, 146062-00, 146062-000, 1489053, 3205659, 5303209192, AH419402, EA419402, PS419402.
