Electric oven in Candy range shows Er01 and will not heat

Safety first: Disconnect the range from mains before removing panels or the back cover.

• Locate sensor: Inside the oven cavity, find the temperature probe (usually at the rear or top). Inspect for physical damage.
• Check wiring: From the rear, trace the sensor wires to the electronic control board. Ensure connectors are fully seated and not burnt.
• Measure resistance: With a multimeter, measure the sensor resistance at room temperature and compare with Candy specifications. Replace the sensor if open, shorted, or out of range.
• Control board: If a new sensor does not clear Er01, the oven control board’s sensor input may be defective and require replacement.
