If your fridge isn’t staying cold or the door isn’t closing properly, it might be time to replace the fridge magnetic seal. This simple yet essential fix helps your refrigerator maintain the right temperature, reduces energy waste, and prevents food spoilage. In this guide, we’ll show you how to replace a fridge magnetic seal step-by-step, explain when it’s worth replacing, and answer common questions about fridge seal maintenance.
Why the Magnetic Fridge Seal Matters
The magnetic seal (also known as the door gasket) is the flexible strip that runs around the edge of your fridge door. It creates an airtight barrier to keep cold air inside and warm air out. When the seal becomes cracked, warped, or loses its magnetism, it can lead to:
- Temperature fluctuations
- Frost build-up
- Higher energy bills
- Food spoiling faster
In short, a faulty seal means your fridge is working harder than it should, and it’s time for a replacement.
Magnetic vs Standard Fridge Seals – What’s the Difference?
If you work with commercial refrigeration, you’ve probably heard the term magnetic fridge seal but how does it differ from a standard door gasket?
In most modern commercial and domestic fridges, the door seal includes a magnetic strip inside the flexible rubber or PVC casing. This magnet draws the door tightly against the frame, maintaining an airtight seal to keep cold air inside and warm air out. It helps the door close automatically and ensures consistent temperature control, vital in commercial environments where energy efficiency and food safety standards matter.
Older or specialist compression seals (non-magnetic types) rely purely on pressure or clips to stay closed. These are still found in some heavy-duty or legacy commercial units, but they’re less common today as magnetic seals are easier to fit, maintain, and replace.
So, when you see guides on how to replace a fridge magnetic seal, it usually refers to the same magnetic-style gasket used across most modern commercial and catering fridges. This kind ensures tight closure and reliable temperature retention.
How to Tell if Your Fridge Seal Needs Replacing
Before learning how to replace a fridge magnetic seal, check whether yours actually needs it. Common signs include:
- The fridge door is not sealing properly or pops open.
- Visible damage, such as cracks or warping.
- Cold air leaks or condensation around the door edge.
- The “paper test” fails; close the door on a piece of paper; if it slides out easily, the seal isn’t gripping.
- You notice higher energy use or food not staying as cold.
If one or more of these symptoms appear, it’s time to fit a new seal.
Step-by-Step: How to Replace a Magnetic Strip on a Fridge
Follow these steps to fit a new seal safely and correctly:
Step 1: Buy the Correct Replacement Seal
Check your fridge model number (usually found inside the door or behind the salad drawer) search for it on our website, and order a compatible replacement fridge magnetic seal.
If you don’t know the model number, you can order a PVC or rubber bespoke replacement and have the replacement seal in no time.
Step 2: Remove the Old Seal
- Unplug the fridge for safety.
- Starting at a corner, gently peel back the old seal. Most are held in place by a retaining lip or small screws.
- If screws are used, loosen them slightly (don’t remove entirely).
- Pull the seal out, working around the door.
Step 3: Clean the Door Groove
Wipe away any dirt, mould, or residue using warm soapy water. A clean surface ensures the new seal sits flush and forms a proper airtight bond.
Step 4: Fit the New Magnetic Seal
- Align the new seal with the groove.
- Push or slide it into place, starting from the corners.
- If your model uses screws, tighten them gently once the seal is fully inserted.
- Run your fingers around the edge to ensure it’s secure and even.
Step 5: Warm the Seal for a Perfect Fit
Use a hairdryer on a low setting to soften the seal slightly, allowing it to mould to the door shape. Close the door and let the fridge rest for a few hours before plugging back in.
Can I Replace the Fridge Seal Myself?
Yes, replacing a fridge seal is a DIY-friendly job. Most people can do it in under an hour with minimal tools, but it can be done in as little as 3.5 minutes once you know what you’re doing! However, you should:
- Always unplug the fridge first.
- Make sure to buy the right size and type of seal.
- Avoid over-tightening screws or stretching the seal.

Is It Worth Replacing a Fridge Seal?
Absolutely. A damaged seal can waste up to 20% more energy, putting unnecessary strain on your appliances and increasing energy costs. Replacing it is much cheaper than buying a new fridge and can quickly pay for itself in energy savings.
As a rule of thumb:
- Inspect your seal regularly.
- Replace every 6-12 months in commercial settings and every 3-5 years domestic appliances, or sooner if it shows damage.
Common Mistakes to Avoid
- Not cleaning the groove properly before fitting.
- Forcing the seal into place, causing tears or gaps.
- Skipping the warm-up step, which can stop the seal from sitting evenly.
- Ignoring door alignment issues, check hinges and level the fridge if needed.

FAQs About Replacing Fridge Magnetic Seals
How much does it cost to replace a fridge seal?
On average, businesses can expect the total cost to replace a refrigerator door seal to fall in the range of £40 to £140, depending on door size, seal specification and labour/parts mix.
- The part alone for stock-profile seals typically runs around £20 to £60.
- Labour (or call-out) for commercial replacements, especially where travel and downtime are factors, can add a significant portion of the cost.
Why is my magnetic strip not working?
The magnet may have weakened or become misaligned. Try re-magnetising or replacing the strip. For a weak magnet, it’s often fixed by taping the door shut overnight, which gives the magnet time to properly magnetise to the door. Sometimes it’s hard for them if the door is misaligned. You can see more helpful tips on this in this guide on achieving the perfect seal.
Can a fridge work without a seal?
It will technically run, but it won’t cool efficiently and will waste energy, which is not recommended.
