A new refrigerator door gasket comes out of the box twisted from packaging, and it will not seal properly until it relaxes flat. That is true whether you spend $40 or over $130 on it. Buyers who warmed the new gasket with a hair dryer, set it in the sun, or just let it sit overnight got a seal. The shipped instructions for this gasket say the same thing in their own words: let it reach room temperature before you judge the fit.

If you drive a Whirlpool WRX735SDHV00, WRMF3636RB00 or GZ25FDRXYY0, the fresh food door gasket you want is W10830274. It is not the right part for every door on that fridge, which the gasket section below covers.

Before you take anything apart, unplug the refrigerator.

Check these two things before you order a gasket

A gasket that will not seal can look exactly like a door that is hanging out of level. One buyer’s new gasket only sealed properly after they leveled the door and shimmed it with a 1/16 inch washer. If your door looks crooked in its frame, or seals tight on one side and gaps on the other, that is a door alignment problem to rule out first, not a reason to buy a second gasket.

The other free check is the surface the gasket presses against. One reviewer reported that cleaning that surface made a real difference to how well the new gasket sealed. Wipe it down before you install anything, new or old.

Neither check costs anything, and both can save you from buying a gasket your door didn’t need.

Why a new gasket needs time before it will seal

The research behind this guide is thin: 19 reviews read in full, across listings covering about 53 ratings. Within that small set, one thread comes up again and again. A gasket ships compressed and twisted inside its box, and if you install it straight out of the packaging it will not seal at all. Several buyers independently found their own fix: one used a hair dryer, another set the gasket out in the sun and had it fitted in five minutes once it had warmed, a third simply spread the seals out the day before installing. The packaging instructions themselves tell you to let the gasket reach room temperature first.

One reviewer reported it took about a week after installation before the gasket fully acclimated and sealed well. That is a single account, not a measured rate, so take it as one data point rather than a guarantee of timing. I found nothing in this research that tells you how often relaxing the gasket actually fixes a bad seal, so I’m not going to invent a figure for you.

Which gasket fits which door

W10830274 is the fresh food door gasket for the Whirlpool WRX735SDHV00, WRMF3636RB00 and GZ25FDRXYY0. It comes in gray at every retailer checked. There is no other color listed for it, so don’t go looking for a color code that doesn’t exist.

PartSelect states that this gasket is the same part for both sides of the door, with no separate left-hand or right-hand version. You don’t need to figure out which side you have before you order.

If you own the WRMF3636RB00, the freezer door is a different story. Its gasket is WPW10714545, a separate part from W10830274. Ordering W10830274 for that door will get you a gasket that doesn’t fit it. The fresh food door and the freezer door are not interchangeable on this model.

For fitment, PartSelect’s own listing for W10830274 covers the GZ25FDRXYY0. It does not list the WRX735SDHV00 or WRMF3636RB00, even though both are confirmed fits through Whirlpool’s own parts site and through Sears PartsDirect. If you only checked PartSelect’s fitment tool against one of those two models, it would have told you the part doesn’t fit when it does. Check more than one source before you rule a part out.

Making sense of the numbers stamped on the part

W10830274 is the current Whirlpool number for this gasket. It replaces two older Whirlpool numbers, W10443273 and W10294127. If your old gasket is stamped with either of those, W10830274 is the replacement.

Two other numbers show up for the same physical part and neither one is a Whirlpool number. AP6027236 is a distributor’s number. PS11759518 is PartSelect’s own catalog number for it. You’ll see either depending on who’s selling it to you, but they both point at the same gasket Whirlpool calls W10830274.

A number you’ll sometimes see is 4454925. That’s a retailer’s item number, not a Whirlpool part number at all.

If you pull the old gasket and find a number molded directly into the rubber, that’s usually the oldest of the three Whirlpool numbers. That won’t always match what’s printed on a sticker or on your invoice, since a distributor or retailer may have sold the part under their own number at some point.

What one aftermarket buyer found

One reviewer, in a single tier-3 report, bought an aftermarket gasket running around $40. After letting it relax overnight, it installed and sealed, and this buyer needed no hair dryer or sun treatment to get there. The one difference they noted against the original was that the magnets held slightly weaker than the OEM gasket’s, though the door still closed and stayed closed. That’s one owner’s account, not a verdict on aftermarket gaskets generally, and the research gives nothing on how that magnet strength holds up over time.

What W10830274 costs

Across the retailers checked for this guide, W10830274 ran from $133.42 to $154.10 at the time the research was done. A $110 price you’ll sometimes see cited for this part is lower than anything found at research time.

FAQ

How much does a new fridge door gasket cost?

W10830274 ran $133.42 to $154.10 across the retailers checked for this guide. A commonly cited $110 figure is lower than that.

Does the same gasket fit the freezer door on my WRMF3636RB00?

No. The freezer door on that model takes WPW10714545, a separate gasket from the fresh food door’s W10830274.

Is a $40 aftermarket gasket as good as the Whirlpool one?

One review is all the research has: it sealed after an overnight relax with no heat needed, and its magnets held slightly weaker than the OEM gasket’s. Whether that weaker grip holds up long term isn’t something this research can answer.

My old gasket says W10443273. Can I order W10830274 instead?

Yes, W10830274 replaces W10443273. You may also see AP6027236 or PS11759518 listed for the identical part; those are just other sellers’ numbers for it, not different parts.

Should I check anything before I buy a new door seal?

Check that the door hangs level and that the surface the gasket presses against is clean. One buyer’s seal only came right after leveling the door and shimming it with a 1/16 inch washer, and a clean sealing surface made a difference for another.
