Start with the sequence
For this Montpellier oven complaint, note whether food undercooks or overcooks and if the display changes. Record the last normal stage and the first change. A short description of that sequence is more useful than a guessed part name.
What might explain it?
The temperature result changes can involve temperature sensing, control or a selected function. Those are possible areas for assessment, not a confirmed diagnosis or a claim about a particular Montpellier model.
Compare the selected setting with the result you actually observed. Mention whether other functions on the same appliance still operate. Avoid repeated resets, bypassing locks or testing internal components.
The Montpellier identification matters
Look for the accessible label around the oven door opening. For a double oven, state which cavity is affected.
The badge covers more than one product family. Identify the particular appliance from its complete rating plate; matching names or styling do not establish parts compatibility.
A display code only has meaning alongside the exact product and its documentation. Photograph the full message rather than looking up a similarly named model and assuming it uses the same code system.
Before a visit for this complaint
Record built-in, built-under or freestanding fitting. Do not remove the oven from its cabinet to find a number.
Give the full address postcode, not just Catford or SE6. Appointment availability, the repair approach, charges and any parts requirement are confirmed individually.
