Display shows TEMP PROBE error and grill will not maintain set temperature

Safety: Disconnect power before plugging or unplugging probes if the controller behaves erratically.

• Remove accessory probes: Unplug any meat or auxiliary probes from the front panel jacks. Power cycle the grill and see if the error clears.
• Inspect probe and cable: Check the stainless probe tip and cable for kinks, cuts, or melted insulation. If damaged, replace the probe with a Memphis-compatible meat probe.
• Test probe resistance: With a multimeter, measure resistance across the probe plug. A typical probe will show a finite resistance (often 1–100 kΩ depending on type). An open or zero reading indicates a bad probe.
• Check jacks: Inspect the probe jacks on the controller for grease, moisture, or corrosion. Clean gently with contact cleaner and a cotton swab.
• Test with known-good probe: Plug in a new or known-good probe and verify that the controller reads a reasonable temperature. If the TEMP PROBE error persists with a good probe, the jack or controller input is likely faulty and the controller may need replacement.
