I was using my grill at high heat tonight (3rd party thermometer read over 500) the GMG display and phone app read zero.  If I adjusted the temp it would read what the GMG was “at.” Has anyone experienced this or have an idea of the cause?

Thanks,
Jon

Time to call GMG CS.  I've always had my questions answered by them.  Good luck.

No idea how to help.

Thanks for the replies guys.  GMG CS thinks its the thermal sensor. I ordered a new one yesterday, about 15 bucks shipped. Pretty cheap fix!

 Please let us know how you made out after the part is changed.  Successful or not.

I swapped out the part, fired up grill and it seemed to be working again. I haven’t cooked on it since I’ve been using my smaller grill, but I probably will fire it up next week

Good to hear its back working
