Honeywell Compact Quick Heat Ceramic heater with tilt feature - HZ 325

Your prob is their is a thermostatic solinode that is trigger the unit to go off--because it thinks itself as too hot and unsafe to be on--this trigger was defective or damaged by disuse and/or fatigue------give it a shake-- better yet, when cool and unplugged-vacuum or blow out with compressed air-with out disturbing integrity of workmanship on device--if that no worky--time for new one---thermostatic element is dirty, device being of differing Mghz than outlet, if fairly new device--amperage of outlet is too small for device to work properly. If it is a 240 volt or a 120 volt device and your attempiting to use the wrong voltage outlet--STOP USING THE DEVICE
