Dryer Won't Stay Hot: Separate Normal Heat Cycling From a No-Heat Fault
A dryer that warms, then pauses the heat, may be regulating temperature normally; GE explains that a safety thermostat can cycle the heat source off when temperature rises, and automatic cycles may turn heat off as clothes dry. First check whether Air Only or a low-heat setting was selected, then run the manufacturer's basic empty-drum test on a heated timed cycle for five minutes and observe whether the inside is warm.
