Meat probe temperature reading is inaccurate or does not change during cook.

Safety first: Use heat-resistant gloves when handling hot probes.

Step-by-step checks:

• 1. Inspect probe cable: Look for cuts, kinks, or melted insulation. Replace the probe if damaged.
• 2. Clean probe tip: Wipe the metal tip with a damp cloth to remove grease and residue.
• 3. Test in boiling water: Place the probe tip in boiling water; it should read near 212°F (100°C) depending on altitude. Large deviations indicate a bad probe.
• 4. Check jack connection: Ensure the probe is fully inserted into the control panel jack. Wiggle gently to see if the reading drops out, indicating a loose jack.

When to call a technician: If multiple known-good probes read incorrectly, the control board probe input may need replacement.
