Why is my thermometer throwing an AH code and how do I clear it
Try a new high quality battery. That solved the problem with one guy with the same issue: https://www.amazon.com/review/RZ37J3P397…
Hi @dogglb27 , I suggest that you contact the manufacturer and ask them. It never hurts to ask.;-) If the manufacturer informs you that it is faulty and cannot be repaired, how long have you had the thermometer? There is a 1 year manufacturer’s warranty (plus additional 1 year if registered with the manufacturer) on the product. If your thermometer is still within the warranty period, ask them what you have to do to claim a manufacturer’s warranty replacement or refund.
