The digital timer, temperature and the heating element is shut off and won't turn on. Your smoker is equipped with a thermostat (high limit safety shut off) to give added safety in case of electrical failure within the appliance and could be damaged. Unplug and reconnect the thermostat by removing the cover plate located on the back of the smoker and try again. If that doesn’t solve this issue the thermostat will need to be replaced. Refer to your Manual, on how to locate and replace the thermostat.
