I have a Maverick ET-732 and I am on my second Maverick ET732 Genuine Smoker & Chamber Probe (BBQ Pit Temp Probe). Here's my issue... During a cook, the temperature display will jump up and down, display LLL and/or HHH and then eventually go back to what i assume is the correct temperature. As an example, this is what i might see in a 10 minute period - 275, 400, 150, LLL, and then back to 275. This will happen 3-4 times in a 2 hour cook. My original probe did not do this. Has this happened to anyone else? Why does it do this?
