Description
Original PT1000 temperature sensor for Miele ovens Miele 7912804
The original Miele PT1000 temperature sensor 7912804 is the component responsible for accurate temperature measurement in the H2661, H2861 and H6461 built-in & freestanding oven series. The sensor is based on a platinum resistor with a value of 1000 ohms at 0°C – an industry standard that ensures accurate measurement over the entire temperature range. A sensor failure results in inaccurate heating, uneven cooking, and an F9 error code. The original part ensures perfect compliance with Miele control protocols.
About 70% of temperature problems in Miele ovens that come to our technicians end up with replacing the PT1000 sensor alone. Is the oven displaying an F9 code? Is the temperature not reaching the target? Is the baking uneven even in the ventilation program? These are the classic signs of sensor failure. Now click the “Check Model Compatibility” button at the top of the page for immediate confirmation that the part is suitable for your appliance.
What causes error code F9 on Miele ovens?
Code F9 appears when the control system detects an open circuit in the PT1000 sensor – that is, the sensor is not transmitting a correct temperature reading. Common causes: a burned-out sensor due to prolonged exposure to extreme temperatures (over 300°C), a break in the wiring, or oxidation of the contacts. In our experience, in 80% of cases the sensor itself is the cause – not the wiring.
The PT1000 sensor uses a platinum resistor that changes its value linearly with temperature. At 0°C the value is exactly 1000 ohms; at 100°C – approximately 1385 ohms. The Miele control system reads these values and calculates the temperature in real time. A non-original platinum sensor will produce incorrect readings – even if it does not stop working completely.
⚠️ Important: Replacing the temperature sensor in Miele ovens requires professional technical knowledge. It is recommended to call a qualified technician from the official service. Incorrect installation may cause constant temperature inaccuracy and repeated error readings.

🔧 How do you replace the PT1000 temperature sensor?
⚠️ This is a complex replacement part that requires technical knowledge. Replacement involves access to the rear compartment of the oven and the internal wiring. Do not attempt to replace it yourself – contact a qualified technician.
Before calling for service – an initial check you can perform:
- Unplug the oven for 15 minutes – reset the control
- Restart and check if the F9 code still appears.
- If the code returns immediately – the sensor has failed and requires replacement.
- Contact a Miele certified technician with part number 7912804
💡 Tip from the experts
From the experience of our technicians – before confirming the sensor failure, it is worth checking it with a multimeter. A normal PT1000 sensor shows about 1100-1110 ohms at room temperature (25°C). A reading outside this range – a failed sensor. If the multimeter shows OL (open circuit) – there is no doubt: the sensor is dead and must be replaced. Technicians who perform this test often also avoid a mistake in “wiring” that does not solve the problem.
❓ Frequently Asked Questions
What are the signs of a temperature sensor failure in a Miele oven?
Error code F9 is the most obvious sign. It is usually preceded by: uneven baking despite a proper ventilation program, temperature not reaching the set target, and heating that behaves unexpectedly. An oven that displays F9 and does not heat – it should be unplugged and a technician should be called.
Will a non-original PT1000 sensor work?
Not recommended. Original Miele PT1000 sensors are manufactured with a measurement tolerance of less than 0.5°C over the entire range. Non-original sensors sometimes work within a narrow range and deteriorate quickly. The result: uneven baking that increases over time, and eventually a recurring error code. An original sensor is the right decision for years of precise baking.
How long does it take to replace the sensor?
A qualified technician with the required experience performs the replacement in an average of 30-45 minutes, including disassembly, replacement, and functional testing. After the replacement, calibration and readings must be checked at several temperature points.
