Has anyone had problems with a Condar digital CAT temp. probe? I loaded up the insert tonight and waited and waited and waited for the CAT temp reading to start climbing but it never did. The readout read COOL for 35-40 mins. I looked up into the stove at the CAT and it was glowing kind of a dull orange. I decided to close the bypass and immediately it lit off a bright orange. The reading still read COOL. I just changed the battery two nights ago because it was kind of acting funny. I changed the battery again tonight, as I picked up the meter it flashed between 350 and 500. I finally got it to settle in but still after 10-15mins. it was only reading 850. Usually about this time it's cruising around 1100+. Has anyone else experienced this with their Condar? It's a new unit, I just installed it earlier this year and it's probably got less than 300hrs of burn time.
