Fix a non-working or erratic temperature display on your Gozney Arc or Arc XL oven. Step-by-step diagnosis for battery, connection, and sensor issues.
Quick answer
Most Arc and Arc XL temperature display issues are caused by dead or incorrectly installed AA batteries, a loose connection, or a damaged display unit. Follow the diagnosis steps below to isolate the cause and decide whether a simple fix or a replacement part is needed.
Before you start: what the display does and doesn't do
The Arc and Arc XL temperature display shows the internal oven temperature during use. It is a standalone digital unit powered by two AA batteries and communicates with a sensor inside the oven. It does not control the gas flame or the oven's heating—it only reports temperature.
If the display is blank, shows erratic numbers, or reads 'Err,' the problem is almost always in the power supply, the sensor connection, or the display unit itself. The oven will still heat normally even if the display is not working.
When to consider a replacement display
The original Arc and Arc XL come with the temperature display included as standard. Gozney sells the Arc and Arc XL Temperature Display as a spare part for cases where the original unit is lost, damaged, or has failed after troubleshooting. It is not a routine maintenance item.
If you have confirmed good batteries, a secure connection, and the display still does not power on or shows persistent errors, a replacement display is the next logical step.
Arc and Arc XL temperature display diagnosis
- Symptom: Display is completely blank: Check that two fresh AA batteries are installed with correct polarity (+ and -). Replace with new alkaline batteries if the existing ones are old or weak. If the display still shows nothing, proceed to the next step. Most blank displays are fixed with fresh batteries.
- Symptom: Display flickers or shows partial numbers: Remove the display from its cradle and inspect the metal contact pins on the back of the unit and inside the cradle. Clean any corrosion or debris with a dry cloth. Re-seat the display firmly. If the issue persists, the display unit may have internal damage. Clean contacts and a secure fit often resolve flickering.
- Symptom: Display shows 'Err' or wildly inaccurate temperature: This indicates a sensor communication error. Turn off the oven and let it cool completely. Check that the sensor wire inside the oven is not pinched, cut, or disconnected from the display cradle. If the wire appears intact and the error continues, the sensor or display unit may need replacement. An 'Err' reading after checking the sensor wire means the display or sensor is faulty.
- Symptom: Display works but reads incorrectly after cleaning or moving the oven: The display may have been dislodged from its cradle. Remove and reinstall it, ensuring it clicks into place. If the reading remains off, allow the oven to stabilize at room temperature for 10 minutes—the sensor recalibrates gradually. Re-seating the display usually fixes post-move reading errors.
