When smoking pork chops my remote reading thermometer stopped climbing at about 135 degrees. Checked with another thermometer and it also read 135. Used a thermometer to confirm the internal temperature of the smoker and it was 230 degrees. Waited at least 30 minutes and the temperature remained at 135, by this time the chops had been in the smoker for over 2 hours. Trying to find out why temperature stopped rising at135.
