Back in June I was given a Maverick ET-732 remote thermometer set. I has served me well for the most part til Sunday. I put a ham in the pellet grill and turned on the Thermometer. The remote was registering well and took it inside and set it on the counter. After about 5 minutes it beeped and the screen went blank. Maybe the battery's were getting bad so I replaced both sets. Restarted the units and took the remote back inside, same thing again. This time I pressed the reset and took it back in only to have it fail again. The sending unit seemed to work just fine. Am I missing something or has my receiver given up on me.
