Bought a GMG Davy Crockett and it arrived this past Wednesday. Unfortunately it stopped working on day 3 :(. Can anyone help troubleshoot this and whether or not it is the thermal unit that's broken?

When turning on the machine, it goes through all the cycles and everything works fine - the auger fills the firebox, there's an adequate amount of pellets in the firebox and it's not full of ash or overfilled with pellets. The igniter heats up, then the pellets start smoking, and the grill heats up perfectly fine. I stuck the food probe in the grill as well as my own temp sensor and it shows that the grill is heating up. Only problem is that the grill doesn't know that. During this stage the grill reads the temp as 50 degrees the whole time even as the temp rises towards 150 according to the food probe and my own thermometer probes I put in there. So the grill temp displays 50 degrees until "FAL" shows up and the grill stops the startup process.

So what do you guys think. Broken thermal unit? Anything I should try?
 
From the manual it sounds like the igniter is faulty


Grill didn’t light (FAL message).
There may be too much ash in the firebox. Wait until it cools off, and clean out the ash. Alternatively, pellets may have overfilled the firebox. Never turn the grill off and on repeatedly as this will overfill the firebox with pellets. Each time the grill displays “0” on start-up, it feeds a full load of pellets into the burn pot. The igniter won't light the pellets unless air can flow freely through the combustion chamber.
The combustion fan may not have been operating. Check to make sure that the fan blades turn freely and the fan runs on cycles 2 and 3 of the 0-1-2-3 sequence.
The auger might not have turned pellets into the burn pot. Refer to “No pellets in the firebox” above.
If there isn’t any ash or pellet buildup, the fan works properly, and fresh pellets are feeding in, your igniter is most likely out and the grill will require a replacement.
*The grill can be manually lit if the igniter is out. Charge the burn pot with a handful of pellets, and light them with a propane torch or. Once the pellets are able to maintain a flame by themselves, plug the grill in so it displays “off.” Hold the “power” button for 10 seconds. The grill will initially display “0” but then skip to a temperature reading while turning on the fan and auger. Let the grill come to 150 then select your grilling temperature like normal.
