Hello, I recently acquired a Pit Boss grill and I'm loving it so far, but I've encountered an issue with an "erh code" popping up on the display. I've scoured the manual, but I can't seem to find any information about what this code means or how to resolve it. Has anyone else faced this ERH code situation before? I'd greatly appreciate any insights or advice on how to troubleshoot and fix this issue so I can get back to grilling without any hiccups. Thanks in advance for your help!
