The Frost Free Freezer is icing up badly.
The Frost Free Freezer is icing up badly. Either magnetic door seal, thermostat or sensor have failed. The fridge and freezer still maintain required temperatures.

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Hotpoint frost free freezer icing up heavily while temperatures remain normal
- The problem
- A Hotpoint fridge freezer with a frost free freezer section was icing up badly, although both fridge and freezer were still maintaining the required temperatures.
- Likely cause
- The accepted diagnosis was that heavy icing on a frost free freezer is more likely to be due to door sealing, air circulation, the defrost system, or a blocked defrost drain than the thermostat itself. A thermostat or sensor fault was mentioned as possible, but not supported by any test result.
- What fixed it
- Recommended action was to inspect the door seal for gaps, splits or poor contact, check whether ice was forming mainly around the door opening or behind the rear panel, listen for the internal fan, and consider a defrost-system fault such as heater, sensor, thermal fuse or control issue if ice was building behind the panel. The exact repair was not confirmed in the discussion.
- Checks to try
- Checked that fridge and freezer temperatures were still correct
- Inspect door seal for gaps, splits, hardened areas and uneven pull
- Paper-grip test around the door seal
- Check door alignment and that drawers or shelves are not preventing proper closure
- Observe where the ice is building up
- Listen for the internal fan
- Check whether the defrost drain is blocked
- Parts or tools mentioned
- Door seal
- Internal fan
- Defrost heater
- Defrost sensor
- Thermal fuse
Safety: Isolate the appliance from the mains before inspecting internal parts. Further diagnosis should be carried out by a suitably qualified appliance engineer.

If a Hotpoint frost free freezer is icing up badly but still holding the right temperatures, the fault is often with air circulation, defrosting, or door sealing rather than the thermostat itself. A thermostat or sensor issue is possible, but if temperatures are still normal it is less certain.
1. Check the door seal carefully Look for gaps, splits, hard sections, or places where the seal is not pulling evenly onto the cabinet. Close a thin piece of paper in several places around the door and see if it grips firmly. Also check the door is aligned properly and not being held slightly open by a drawer or shelf.
2. Look for signs of where the ice is building If ice is mainly around the door opening, suspect the seal or door being opened frequently. If heavy ice is building on the back panel or behind it, that points more towards a defrost fault.
3. Listen for the fan A frost free freezer relies on an internal fan to move cold air. If the fan is not running, or is being obstructed by ice, moisture can build up and cause severe icing.
4. Consider the defrost system A failed defrost heater, defrost sensor, thermal fuse, or control issue is a common cause of heavy icing in frost free models. This usually causes ice to build up behind the rear freezer panel first.
5. Defrost drain If accessible, check whether the defrost water drain is blocked, as this can also lead to ice build-up.
Before inspecting any internal parts, isolate the appliance from the mains. If ice is behind internal panels or you suspect a heater, sensor, wiring, or control fault, it is best checked by a qualified appliance engineer.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
