The cabinet temperature reading jumps erratically up and down.

Safety first: Unplug the smoker before accessing the wiring.

Steps:

• 1. Inspect the wiring: Check the probe leads at the controller for loose or corroded connections. Reseat the connectors.
• 2. Flex test: Gently wiggle the probe cable while watching the temperature reading (with the smoker ON). If the reading jumps, the cable is likely damaged, and the probe should be replaced.
• 3. Dry the probe: If the smoker was recently washed, allow the probe and cabinet to dry thoroughly.
• 4. Replace the probe: Install a new Cookshack cabinet temperature probe if erratic readings persist.
