On legacy Wolf dual fuel ranges with text error messages, such as the DF series, RTD OPEN means there is an open circuit on the RTD oven sensor. The control cannot read the cavity temperature, so it stops heating to avoid guessing. Owners see RTD OPEN on the display and the oven will not preheat or hold temperature. Baking and broiling both stop while the message is on.
1. Turn the oven off and let it cool fully. 2. Switch the range off at the breaker for two minutes, then back on. 3. Try a normal bake at a moderate temperature. 4. If RTD OPEN returns, stop and call us. Do not reach into the oven rear wall or pull on the sensor wire.
It is the temperature sensor in the oven cavity. The control uses it to know how hot the oven is. RTD OPEN means the circuit to it is broken, so no reading arrives.
OPEN means the sensor circuit is broken. SHORTED means the circuit is shorted. Both stop heating, but they are different readings and point to different checks.
No. The oven needs the sensor to cook safely. We test the circuit and replace what has failed, with the price written before we start.
A technician diagnoses it on site and gives you the price in writing before any work starts.
