Electrocuted my partner, customer service were uninterested
Really disappointed in the unit and the customer service. Had our grill a few years, it was a 2020 model but I suspect we bought it around 2022 so it would be just out of warranty.
Out of the blue the power supply/adapter blew up, blowing the adapter case open and electrocuting my partner when it was plugged in.
A quick google showed MANY people with the same power supply reporting issues ranging from unreliable to dangerous. We had an electrician check the power point and the grill and all was fine except the power supply. Grill was always kept covered and on our balcony out of the weather.
I emailed customer service to advise and ask if they could assist, thought given the seriousness of the fault, the history of similar faults from that unit/adapter reported online and the fact that we bought the unit based on reports of impeccable customer service they could assist.
Alas, I was sent a link to buy a new one at $90 (+$10 postage, of course) and told by the rep it was surprising it had failed...
This is a shame given we had bought all the accessories for the grill as well, it has a rotisserie, the pizza attachment, thermal blankets, the lot. We have sunk a bunch of money into this grill but confidence in the unit and the customer service are gone so will simply move on to something new. Would advise people to avoid GMG based on poor quality and mediocre customer service.

In the trash where it belongs
Well, I finally figured out the best place for my Daniel Boone smoker: the trash.
I’ve owned this GMG Daniel Boone pellet grill for approximately 10 years, and unfortunately the ownership experience was frustrating almost from the beginning. In fact, my support history with these issues goes all the way back to late 2015, not long after purchase.
Over the years I replaced multiple components including control boards, WiFi boards, and temperature probes. Even when functioning, the smoker struggled to maintain accurate and consistent temperatures.
The biggest ongoing problem was moisture intrusion into the pellet/auger system. Despite being stored outdoors with a cover, consistent with the intended use of an outdoor smoker, I repeatedly dealt with swollen pellets, auger jams, and complete tear-downs to get the grill operational again. During the latest repair attempt, the auger itself finally failed.
I also contacted my local dealer regarding these recurring issues and was essentially told they could “find nothing wrong,” despite years of repeated failures and repairs.
I understand that any grill can wear out after a decade. The problem here is not that it eventually failed, it’s that it was unreliable for most of its lifespan. I spent more time troubleshooting, replacing parts, and disassembling this smoker than actually enjoying it.
Maybe GMG’s newer models are better, but this experience completely ended my willingness to purchase another Green Mountain Grill product.
Update after company response:
GMG asked whether the smoker was 10-11 years old. Yes, it is. However, the core issue is that the reliability problems began within roughly 3 months of purchase and continued throughout ownership...
Daniel Boone Issue Timeline (Purchased 8/20/2015)
• 11/26/2015 (3 months after purchase)
Reported major temperature inaccuracies. Grill set to 300° but actual measured temp was approximately 350° using external thermometers. Verified in multiple locations inside grill.
• 01/24/2016
Followed up after firmware updates and troubleshooting. Grill still running dramatically hotter than indicated:
Set to 380°, actual ~455°
Set to 215°, actual ~251°
Described concern that “set it and forget it” functionality was fundamentally inaccurate.
• 02/2016
Food probe failures began shortly after firmware update. Probe displayed “nFd” errors and ultimately required replacement under warranty.
• 05/21/2016
Major malfunction while cooking:
Grill suddenly displayed 542°
Stopped heating properly
Could not be reset
WiFi signal lost
Described grill as “essentially useless at this point.”
• 05–06/2016
Dealer evaluated smoker after repeated issues. Dealer replaced control board and food probe but ultimately stated they “found nothing wrong,” despite repeated documented temp inaccuracies and failures.
• 08/20/2016
Third food probe failure reported. Noted broken internal solder connection despite probe remaining plugged in continuously. Also documented prior WiFi board replacement by dealer.
• 11/2017
Reported control board/button failure. “Up” button stopped functioning entirely. Also referenced prior WiFi board replacement and three prior temp probe replacements.
• 06–07/2018
Severe temperature sensor issues:
Grill reading 347° while OFF
Later reading 273° while OFF
Grill temperatures running 80–100° above actual temp
GMG suggested thermal sensor replacement.
• 08/28/2018
Another major malfunction:
Grill registered 527°
Significant smoke event
Bottom of smoker filled with pellets
Described as “a small campfire”
By this point, documented replacements included:
Main board
Temp probe
Food probe (3x)
WiFi antenna/board
Additional components
• 2019–2026
Continued ongoing ownership issues including moisture intrusion into pellet/auger system causing swollen pellets, repeated auger jams requiring disassembly, and eventual auger failure during teardown.
Summary:
The issue was never that the smoker finally failed after 10+ years. The issue was that reliability problems began within months of purchase and continued throughout ownership across multiple major components and systems.

Hi Mr. Chris Farmer
We want to address this in great detail but can you confirm that your unit is 11 year old unit that you are reviewing?

Not dependable.
I received my smoker as a gift. DO NOT BUY FROM THIS COMPANY! 2 months later my power cord shorts out. Thy sent a replacement. 6 months later, mt igniter goes out. Now, it won't power up. They are good at sending parts, but the product is crappy. Try and get tech support, good luck with that. I will never buy any product from this company.Very CHEAP!

I am not a happy camper.
I bought my Green Mountain Grill, Davy Crockett grill back in 2020. I have had problems with it from day one. I am now replacing the controller board for the fourth time. They claim that the grill can reach 500°F, if you get to that temperature you can watch the paint burn right off of the grill. customer service is worthless.
Response from Green Mountain GrillsMay 21, 2026
Sorry Michael. Sounds like it could be a number of things inckuding heatshield set up or grease tray set up but most likely a firmware update. This unit does go to 550 F.

Nothing but customer service issues…
Nothing but customer service issues (Ledge)
This grill worked perfectly for 1 year after purchasing, after a firmware update, everything went to helena handbasket. Temperature off by 100's of degrees. Either buring the food while you're not looking, or letting it sit raw for hours, The pizza attachment only catches on fire when set at the lowest temp. The company has replaced everything on the grill, but it still doesn't work right. The expensive pizza attachment is the most troublesome. The company doesn't even answer my questions anymore. I'm putting it out by the trash and buying something that works. Piece of crap
Bottom Line: No, I would not recommend this to a friend
