What the U80 error code actually means

Your Dacor oven is showing U80 because it detected a problem with the meat probe, the temperature sensor you insert into food to track its internal cooking temperature. Either the probe itself is damaged, or there is a wiring problem between the probe and the oven's control system. The oven stops the probe-guided cooking function to prevent inaccurate readings that could result in undercooked food.

Questions people ask about U80

What does U80 mean on a Dacor range, oven, cooktop?
U80 indicates a meat probe fault in the upper or single oven cavity. The oven control board has detected either a short circuit or an open circuit in the probe or its associated wiring. The code appears when the resistance reading from the probe falls outside the acceptable range for normal operation. This prevents the oven from using the probe for temperature-guided cooking.
Is it safe to use my Dacor oven while U80 is displayed?
Standard baking and broiling functions that do not rely on the meat probe may still be usable depending on how the oven responds to the fault. However, you should not attempt to cook using the probe-guided mode while U80 is active, as the temperature readings would be unreliable. Resolve the probe fault before relying on that function again.
How much does it cost to repair a U80 error on a Dacor oven?
If the meat probe itself is the problem, replacement probe costs typically range from $30 to $80 depending on the model. If the issue is a wiring harness, parts and labor can range from $100 to $250. A control board replacement, if needed, is the most expensive scenario and can range from $200 to $500 or more for parts and professional installation.
Can I fix the U80 error myself?
In many cases, yes. Start by removing the meat probe from the oven socket and inspecting both the probe cable and the socket for visible damage or debris. If the probe cable is kinked or burned, replacing the probe is a straightforward repair. Testing the probe with a multimeter is the most reliable way to confirm whether the probe itself is the faulty component before purchasing parts.
Will resetting the oven clear the U80 error code?
A power reset by turning off the circuit breaker for 60 seconds may temporarily clear the display, but U80 will return as soon as the oven detects the faulty probe circuit again. A lasting fix requires identifying and correcting the underlying cause, whether that is a damaged probe, faulty wiring, or a defective socket.
