A Low Temp Error is specific for WiFIRE-enabled grills and will occur when the temperature goes below 120ºF/48ºC for more than 10 minutes. If you get this error, you may notice that the grill will try to reignite. Reignitions happen when the grill temperature has dropped below 90% of the set temperature for longer than 4 minutes.
Lower temperatures can be a result of poor-quality pellets, auger failure or ash buildup.
The most common resolution for a Low Temp Error is to restart your grill correctly.
WiFIRE-enabled (or D2) grills require a closed-lid startup, meaning you should preheat your grill with the lid shut. Failure to do so will often result in temperature irregularities throughout your cook. Use the following path to perform the closed-lid startup:
Check your firmware version to see if it is up to date. Check out Firmware Updates for more details.
Other than proper startup, check your pellet quality. Pellets should be shiny and snap easily. Also check if the auger is feeding pellets into the firepot. Silly as it may seem, also check to make sure the grill isn't out of pellets. Your grill will notify you when pellet levels are low, but it is still quite common for Traeger owners to run out of pellets.
An unmaintained grill will often lead to difficulty in getting a grill to the correct temperature. Ash buildup, particularly in the firepot, reduces the hotrod's ability to efficiently bring pellets to their smoking point. You should clean your grill at minimum, every 20 hours of cook, but we suggest cleaning it more often than that.
Ash buildup will also effect your grill's ability to circulate heat efficiently, which in turn will prevent the grill from being able to maintain the set temperature.
