The cheapest problem in the cooling chain and the one that causes most of the rest: an eight-to-twelve-year part that hardens into a shape, a thirty-second banknote test to prove it, and a $430 median repair that is worth making long before the compressor it wears out. Sugar and grease left on the contact face is where 1 of the 5 causes on this page gets settled without buying anything — about 15 minutes, no part needed [S1]. On a refrigerator the complaint is the door has stopped sealing and the refrigerator runs constantly, and it arrives in these words: there is frost or ice building up inside, it will not hold its temperature any more, condensation and black mould around the door, it runs constantly and the power bill went up or the door feels loose or does not pull shut. Parts only come into it once those are ruled out: the completed repairs behind this symptom run $332–$629 [S1], against a replacement from $700.
What a technician actually does
a gasket hardened by age into a permanent shape [S1]
high likelihood pro $332–$629 installed about 90 min
there is frost or ice building up inside it will not hold its temperature any more the door feels loose or does not pull shut
The ordinary failure and the one to test for first, because the check is free and takes thirty seconds: close the door on a banknote so half of it sticks out and pull. Clear resistance means the seal is still gripping at that point; if the note slides out, the seal is gone there. It has to be repeated every eight to ten inches around all four sides and on both doors, because gaskets almost never fail evenly - the hinge side and the bottom corners go first, and the seal can still be perfect along the handle side. S1 puts the life of the part at eight to twelve years: the magnet stays strong, the flexible material around it hardens and takes a set, and once it has set it cannot be revived.
S1 publishes no part-only figure; it prices the completed gasket replacement at a $430 median across 118 jobs with the middle half at $332-629, part, labour and the service call together
a door pulled out of alignment by weight or by hanging on it [S1]
medium likelihood moderate $332–$629 installed about 120 min
the door feels loose or does not pull shut there is frost or ice building up inside
The cause that makes a gasket replacement fail twice: children swinging on a door, or a fully loaded door bin, pulls the hinge out of true. The gasket then contacts unevenly, wears at the point of pressure and leaves a gap at the opposite corner - which is why a new seal fitted to a dropped door behaves exactly like the old one. S1's position is that the hinge has to be dealt with in the same visit, and the maintenance advice is blunt: do not overload the door bins, and deal with a door that has dropped immediately.
no separate hinge figure is published; S1 prices the gasket job itself at a $430 median and notes that the hinge has to be dealt with in the same visit or the new seal fails the same way
a profile ordered for the model instead of the serial [S1]
low likelihood moderate $332–$629 installed about 90 min
the door feels loose or does not pull shut it will not hold its temperature any more
The failure mode of a repair rather than of a refrigerator: the same model number across production years carries different gasket profiles, so the part is matched to the serial and not just to the model. That single detail is why this is a smaller DIY job than it looks on an older unit and a larger one on a modern unit - and it is the first thing to check when a brand new seal still leaks at one corner.
no part-only price is published; the cost of getting it wrong is the same $430 median job done twice, which is why S1 matches the part to the serial number
a seal that is no longer the real problem [S1]
low likelihood pro $670–$1,330 installed about 180 min
it will not hold its temperature any more it runs constantly and the power bill went up
The case where the honest answer is to fit nothing. On an older freestanding refrigerator that already has something significant wrong with it, most often a failing sealed system, the gasket is the cheapest problem the machine has and a new seal does not change the outcome. S1 says it tells customers that on the visit rather than fitting the part - which is also the reason the frost and temperature complaints belong on this page and not only on the compressor page.
no separate figure: the point of the row is that the gasket is not the fault, and the fault behind it - a failing sealed system - is the compressor job S1's own records put at a $511 median
Repair or replace?
Run the banknote test before spending anything, then let the cabinet decide rather than the part price. On a freestanding refrigerator under about twelve years old with nothing else wrong, replace the gasket - roughly $430 against a new machine is not close, and the compressor argument is worse: the same records put a compressor replacement at a $511 median, and years of running against a leaking door is the load that ends one early. On a built-in or premium unit the answer is repair even more strongly, because a $900 gasket on a machine designed for twenty years and built into cabinetry is a maintenance event. The one case to decline is an older freestanding unit with a failing sealed system already: there the gasket is the cheapest problem it has. [S1]
- Typical completed repair: $332–$629 [S1]
- Comparable new unit: $700–$2,500 [S1]
- Plus install and haul-away: $150–$250 — about $850–2750 installed all in [S1]
- Planning life used for the decision: 13 years
- The break-even is not between the gasket and the refrigerator, it is between the gasket and what the leak causes: frost on the evaporator that drops airflow and warms the cabinet, a compressor that never cycles off, condensation on the cabinet and mould in the folds, and finally a sealed-system repair at a $511 median. That chain is why a $430 part on a twelve-year-old freestanding unit is cheap and why a $900 one on a built-in still is. The arithmetic that does not work is fitting a seal to a machine whose real fault is elsewhere.
the gasket itself is an eight to twelve year part in S1's description, and its own repair-or-replace line is drawn at about twelve years on a freestanding unit; the planning figure used across this site's refrigerator guides is 13 years, and S1 notes that built-in cabinets are designed for twenty, which is why the part cost changes the answer far less than the cabinet does. The haul-away and installation allowance is the site-wide $150-250 convention, not a figure from S1
