What is actually happening
On a fridge freezer the freezer side normally does the cooling for both compartments, so a freezer that has stopped freezing while the fridge is still cold is unusual and points at airflow rather than the compressor. The most common cause of all is a thick layer of ice on the evaporator, which stops air moving over the coil no matter how well the compressor is working.
The Montpellier fault codes that point at this
A Montpellier freezer will usually tell you what it thinks is wrong before anyone opens it up. These are the codes we hold for this make that relate to not freezing:
- E00 — The fridge freezer has lost contact with, or isn't getting a proper response from, its automatic ice maker.
- E01 — The fridge can no longer read the temperature in the fresh food compartment, so it has flagged a faulty sensor.
- E02 — One of the temperature sensors inside the fridge freezer has stopped giving the control board a sensible reading, so the appliance is flagging a sensor fault.
- E03 — The fridge's control board has lost a sensible reading from one of the temperature sensors inside the cabinet, so it can no longer control the cooling properly.
- E04 — The sensor that tells the fridge when to defrost has stopped giving a sensible reading, so the appliance has flagged a fault with the fridge compartment's defrost sensor.
- E05 — The fridge freezer has lost a reliable reading from one of its internal temperature sensors — on most models in this range, the defrost sensor on the freezer evaporator.
- E06 — The display panel and the fridge freezer's main control board have stopped talking to each other.
- E07 — The fridge freezer has lost a sensible reading from the sensor that measures the room temperature around it.
If yours is showing one of those, that is a much shorter conversation than a general fault — tell us the code when you book and the engineer can often carry the part.
The usual causes on a Montpellier freezer
- A failed defrost heater or defrost timer, letting ice build up over the evaporator
- A failed evaporator fan, so cold air never circulates
- A door left ajar or a failed door seal, packing the compartment with frost
- A refrigerant leak
- A failed thermostat or sensor
What you can safely check yourself
- Empty it and defrost it fully for twenty-four hours with the door open, then run it again — if it works and then fails a few weeks later, that is the defrost system
- Check the door seal and that nothing is holding the door open
- Listen for the fan when the door switch is held in
Still not freezing?
Most of these need an engineer once the checks above are done. £66 including VAT for an engineer to come out and diagnose it, or £84 in total including VAT if it is put right on the visit and no parts are needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Our engineers work on Montpellier machines week in, week out, so they arrive knowing the machine rather than reading the back of it. Local engineers across Nottinghamshire, Derbyshire and Leicestershire.

Common questions
Why is my Montpellier freezer not freezing?
The freezer is running but the contents are soft or thawing. On a fridge freezer the freezer side normally does the cooling for both compartments, so a freezer that has stopped freezing while the fridge is still cold is unusual and points at airflow rather than the compressor. The most common cause of all is a thick layer of ice on the evaporator, which stops air moving over the coil no matter how well the compressor is working.
Can I fix a Montpellier freezer not freezing myself?
Empty it and defrost it fully for twenty-four hours with the door open, then run it again — if it works and then fails a few weeks later, that is the defrost system. Check the door seal and that nothing is holding the door open. Listen for the fan when the door switch is held in. Beyond those checks this one normally needs an engineer.
What Montpellier error codes mean not freezing?
Montpellier freezers report this through their own fault codes. The ones that point at not freezing are E00, E01, E02, E03, E04, E05. If your machine is showing one of those, that narrows it down considerably — each has its own guide on this site.
How much does a Montpellier freezer repair cost?
