Well you got me stumped on this one as they are both reading air temperature this time and not the grate temperature. Which one was below temperature?
Drop them both in a cup of ice water and see if there is a difference in temperature and if it takes one longer to even out. Then once they have stabilized at the same temperature, take them out and see how long it takes to read current air temperatures. might be a faulty probe.
