Hardened or Flattened Gasket
Age and heat harden the magnetic strip, so it no longer springs back against the frame.
A worn door seal is the smallest part with the largest knock-on cost — warm food, frost, and a compressor that never rests. Potomac Refrigerator Pros takes door seal calls by phone only, Monday to Sunday, 8:00 AM to 10:00 PM. Call (301) 368-8305 with the brand and model if known, where the seal looks worn, and whether the door closes on its own. A written estimate comes before work starts — no form, no email booking.

Name the exact symptom when you call, because a failed seal shows up in several ways: a compressor cycling every few minutes or running nonstop, condensation or sweating between the doors of a French-door model, food spoiling a day early, frost building in the freezer, water pooling under the fridge, or a door that no longer pulls shut on its own. The gasket is the soft magnetic strip around the door frame; when it hardens, tears, or flattens at the corners, cold air escapes and warm Maryland air creeps in. Potomac’s humid summers make a tired gasket worse, because moist air hits the evaporator and freezes into a block of ice, and the compressor then runs longer to hold temperature.
No single symptom maps to one part. Diagnosis is inspection, with a multimeter and temperature readings, not a phone guess.
Age and heat harden the magnetic strip, so it no longer springs back against the frame.
A tear at a corner or hinge side lets a steady stream of warm air into the cabinet.
Old food debris and grease in the channel stop a new seal seating evenly at the corners.
Worn hinge cams or a door bumped out of alignment leave a gap no new gasket can close alone.
Grime and growth on the strip break the magnetic contact and leave daylight gaps.
A strip cut to length, rather than the correct part number for the model, pulls unevenly around the door.
Moist summer air through even a small gap adds frost and condensation faster than the fridge can clear it.
Check the seal for tears, flattening, and gaps at the corners, and wipe debris from the gasket and frame. Try the paper test as a rough guide only: close the door on a sheet of paper and pull gently — it should grip evenly on all four sides, but a pass on one side does not prove the seal is sound. Check whether the door closes on its own and whether hinges look worn. Take a thermometer reading from each section and write both down. Do not force a warped door, remove covers, or touch refrigerant lines. Stop and call if water reaches electrics, you smell burning, or the breaker trips again.
Call (301) 368-8305 with brand and model if known, the brand and model if known, where the seal looks worn, and whether the door closes on its own, and your area or ZIP code.
Diagnose on site: gasket condition on all four sides, hinge cams and shims, door alignment, liner condition, and temperatures are tested. The failed part is named, not guessed.
Written estimate before work: plain-language diagnosis and estimate first, and you decide. If a hinge or liner fault is found with the door off, it is quoted before anything further is touched.
Repair and test: The correct gasket for the model is fitted, the channel is cleaned first, alignment is adjusted, and the seal is tested on all four sides. Temperatures are checked again — fridge at or below 40°F, freezer at 0°F — before the visit ends.
After: how to wipe the gasket, check corners for gaps, and watch for condensation returning between the doors. No fixed-for-life promise, and no term is stated that the partner has not confirmed.
No Potomac-specific repair price dataset exists, and none is invented here. Market figures, not a quote, and not a Potomac price. Your written estimate is the only price that counts.

If repair costs more than about half a comparable new unit, replacement is usually favoured; if far less, repair usually wins. Lifespans (Fridge.com analysis of DOE/AHAM data) are about 14 years for a top-freezer, 13 for a bottom-freezer, and 12 for side-by-side and French-door units, with built-ins about 15 years — guides, not promises.
Repair almost always.
Apply the 50% test: a fan, defrost part, thermostat, or seal is an easy yes, while a sealed-system repair near half the replacement price is not.
Apply the 50% test; minor fixes such as a seal, filter, valve, or thermostat can be worth it at any age.
With a major failure, replacement is usually favoured; sealed-system repair on a standard unit over 10 years old rarely pays.
The exception: a repair buying two or three more years on a perfectly fitting unit can beat a swap needing joinery, and replacement add-ons can add several hundred dollars.
For this fault specifically: a seal replacement is usually an easy yes under the 50% rule at any age, because it is a minor fix that also protects the compressor from strain. If the door itself is warped or the liner is damaged, the replacement comparison comes before any work.

Straight answers for a fridge door seal fault in Potomac, MD — diagnosis first, written estimate before work.
Close the door on a sheet of paper and pull gently — the paper should grip evenly on all four sides. That paper test is only a rough guide: a pass on one side does not prove the seal is sound, and a fail on one side points to the corner or hinge side to report on the call.
Detail: Also look for tears, flattening, and daylight gaps, check whether the door closes on its own, and take a thermometer reading from each section. A technician repeats the pull test on all four sides before and after fitting, so the difference is visible.
Yes. Warm, humid air entering through a torn or flattened gasket hits the cold evaporator and freezes, so frost builds in the freezer and the fridge section can warm. In Potomac’s humid summers, even a small gap adds frost faster than a healthy defrost cycle can clear it.
Detail: A seal leak and a defrost fault often appear together, so diagnosis checks both: gasket condition on all four sides, hinge alignment, and defrost parts. Replacing the gasket without checking alignment can leave the same gap behind.
Yes, because cold air escapes and warm air creeps in, so the compressor runs longer to hold temperature. That extra running also strains the compressor over time, which is why a cheap seal fault left alone can grow into a compressor fault later.
Detail: The research lists longer run times and less margin for a weak-seal unit in hot, humid conditions. A seal replacement is a minor fix under the 50% rule at any age, and it protects the compressor as well as the food.
There is no fixed interval: a seal lasts until it hardens, tears, flattens at the corners, or stops gripping evenly. Age, heat, and how often the door opens all matter, and Potomac’s older homes (median home age about 41 years, 2020–2024 ACS) often hold fridges whose original seals are well past their best.
Detail: Check the gasket when the compressor starts cycling more often, condensation appears between doors, or food spoils early. Wiping debris from the gasket and frame, and reporting a failed pull test early, keeps a seal job minor.
Nationally, most fridge repairs fall in Thumbtack’s 2026 range of $138–$350, most around $220, while HomeAdvisor’s 2025 data runs $200–$1,300, average $650, most $300–$1,000. By part, HomeAdvisor lists door seals at $50–$440, and neither figure is a Potomac price at all.
Detail: A seal job usually sits at the lower end of that spread, but the correct part number varies by model, and a hinge or alignment fault found with the door off is quoted separately before it is touched. A diagnosis and a written estimate before work are the only way to know your figure.
The correct part number for your model is the sound choice, because a universal strip cut to length pulls unevenly around the door and can leak at the corners within months. Model-matched gaskets are made to the door’s shape, magnetic strength, and retainer channel.
Detail: That is why the call asks for brand and model if known: the part can be matched before the visit, and the seal can be tested on all four sides after fitting. A universal strip is a stopgap, not a lasting seal.
