What is actually happening
The single most useful thing to establish is whether the compressor — the motor at the back — is running at all. A compressor that never runs points at the thermostat, the start relay or the compressor itself. A compressor that runs constantly while the fridge stays warm points the other way: either the system has lost its gas, or the airflow from the freezer side is blocked by ice.
The Grundig fault codes that point at this
A Grundig fridge 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 cooling:
- E00 — The temperature sensor in the freezer compartment has stopped giving the control board a sensible reading, so the fridge freezer can no longer tell how cold it actually is.
- E01 — The fridge freezer has lost a sensible reading from the sensor that watches the freezer's evaporator — the cold-producing coil hidden behind the back wall of the freezer — so it can no longer tell when that coil needs defrosting.
- E02 — The fridge section's evaporator temperature sensor is giving a reading the control board won't accept, so the appliance has flagged a sensor fault rather than a cooling fault.
- E03 — The fridge section's air temperature sensor is no longer giving the control board a sensible reading, so the appliance has flagged a fault rather than trusting it.
- E04 — The freezer's automatic defrost heater isn't doing its job, so ice is building up on the evaporator instead of being melted away.
- E08 — The control board has lost a sensible reading from the temperature sensor in the ice maker compartment, so it has flagged a fault and stopped trusting that part of the system.
- E09 — The automatic ice maker's motor isn't turning as the control board expects, so the fridge has flagged a fault with the ice-making mechanism rather than with the cooling itself.
- E10 — The fridge freezer has lost a reliable reading from the air temperature sensor in its third, convertible compartment, so it can no longer control the temperature in that zone properly.
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 Grundig fridge
- A failed thermostat or temperature sensor, so cooling is never called for
- A failed start relay or compressor
- A slow refrigerant leak, leaving the system with too little gas
- A blocked evaporator or failed defrost system choking the airflow
- Condenser coils at the back thick with dust, or the appliance jammed tight against a wall
What you can safely check yourself
- Put a hand on the back of the appliance — a working compressor is warm and audible
- Check the thermostat has not been knocked to its lowest setting
- Pull it out and vacuum the coils at the back, and leave a gap for air to circulate
- Check the door seals shut cleanly all the way round — a note of paper shut in the door should grip
Still not cooling?
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 Grundig 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 Grundig fridge not cooling?
The fridge is running but the inside is not cold. The single most useful thing to establish is whether the compressor — the motor at the back — is running at all. A compressor that never runs points at the thermostat, the start relay or the compressor itself. A compressor that runs constantly while the fridge stays warm points the other way: either the system has lost its gas, or the airflow from the freezer side is blocked by ice.
Can I fix a Grundig fridge not cooling myself?
Put a hand on the back of the appliance — a working compressor is warm and audible. Check the thermostat has not been knocked to its lowest setting. Pull it out and vacuum the coils at the back, and leave a gap for air to circulate. Check the door seals shut cleanly all the way round — a note of paper shut in the door should grip. Beyond those checks this one normally needs an engineer.
What Grundig error codes mean not cooling?
Grundig fridges report this through their own fault codes. The ones that point at not cooling are E00, E01, E02, E03, E04, E08. 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 Grundig fridge repair cost?
£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.
