TLDR
On your BAKERLUX SHOP.Pro unit, error U14 indicates a temperature probe warning in the hood. This typically points to a disconnected, faulty, or incorrectly installed temperature sensor. Begin by verifying the probe's connection and electrical integrity.
Technical Details
Repair Steps:
- Verify Temperature Probe Connection: First, ensure the temperature probe for the hood is securely connected to the P7 socket on the hood power board. A loose or disconnected wire is a common cause for this warning.
- Test Temperature Probe Impedance: Disconnect the temperature probe and use a multimeter, set to ohms, to measure its impedance. At 25 °C (77 °F), a properly functioning probe should read approximately 110 ohms. If the reading is significantly off or open/shorted, the probe is faulty.
- Replace the Temperature Probe: If the impedance test confirms the probe is defective, or if the connection was secure but the error persists, replace the temperature probe with a new, genuine UNOX replacement part.
- Inspect and Replace Hood Power Board: If the probe is confirmed good and correctly connected, but the U14 error persists, the issue may lie with the hood power board itself. Carefully inspect the board for any visible damage, burnt components, or signs of water ingress. If no other cause is found, replacing the hood power board may be necessary.
Common Questions:
Q: What does the UNOX U14 error code signify?
A: Error code U14 on your UNOX BAKERLUX SHOP.Pro unit indicates a warning related to the hood’s temperature probe, suggesting it might be disconnected, faulty, or providing an incorrect reading.
Q: What is the correct impedance for the hood’s temperature probe?
A: When testing the temperature probe with a multimeter set to ohms, it should ideally measure around 110 ohms at 25 °C (77 °F) for proper functionality.
Q: Is it safe to operate the oven with a U14 temperature probe warning?
A: Operating the oven with a faulty temperature probe is not recommended as it can lead to inaccurate cooking temperatures, affecting food quality and potentially creating unsafe cooking conditions. It’s best to address the error promptly.
