Andersen 400 Series Frenchwood gliding patio door: how to identify it and where repairs go

The short answer

Andersen's 400 Series Frenchwood gliding patio door has a natural wood interior and a vinyl exterior. Andersen calls it a classic gliding door with a French door look; its product page is headed "400 Series Gliding Patio Door," and its sizing documents use the Frenchwood name.

Two facts decide most repairs: which parts are handed, which differs from Andersen's other gliding doors, and when the door was made, which changes the lock adjustment. Andersen's roller and lock adjustments are done with the panel in its frame. Replacing rollers takes the panel out, and this site leaves that to a professional.

Every statement here comes from Andersen's own documents, opened on November 6, 2026 and linked at the bottom. It applies to the 400 Series Frenchwood gliding door only. This site is not affiliated with Andersen.

Is it a 400 Series Frenchwood?

The inside of the door. Andersen says 400 Series products are mainly wood with a Perma-Shield exterior cladding, a high-grade vinyl formed around the wood. Its panel guide says this door's interior surface must be finished, by painting or staining, for example. Andersen's 2022 sheet says wood interiors are unfinished unless prefinished white is specified. The sheet also says maple and oak interiors are offered on 400 Series Frenchwood patio doors only.

The doors it gets mistaken for.

• 200 Series Perma-Shield gliding. The name overlaps, but Andersen says this door has a vinyl-clad interior. From 1968 to 1998 it also came as a three-panel door in one frame; Andersen's Frenchwood handing article shows no three-panel unit.
• 200 Series Narroline gliding. Andersen describes it as wood protected by a vinyl exterior, and says it has a wood interior, so the inside alone does not separate it from the Frenchwood. Check the label. The Andersen 200 Series gliding door guide covers how to tell the Perma-Shield and Narroline doors apart.
• A-Series gliding. Andersen also uses the Frenchwood name for an A-Series gliding door (guide 0005414); its 400 Series gliding door page describes the A-Series gliding door as wood protected by fiberglass exterior. The Andersen A-Series and E-Series guide covers that door and how to tell the two Frenchwood doors apart.
• 100 Series gliding. Andersen says the 100 Series is Fibrex composite material inside and out. The Andersen 100 Series guide covers that door.

The label. Andersen says its Product ID label gives the Series, size, color, and glass type, and shows one 400 Series label style for products made from 2003 to July 29, 2007, and another from July 30, 2007. Its label guide says to look for a gliding door's label first at the top of the door frame, and puts the label on a Frenchwood stationary unit or sidelight at the bottom of the frame, under the interior trim stop. Andersen's glass etching carries a manufacturing date: when the door was made, or when a panel was replaced. The maker label guide covers the glass logo.

Handing, and which parts are handed

Andersen hands the Frenchwood from outside, by where the operating panel sits: operating panel on the left is a left-handed unit. A four-panel door has two operating panels between two stationary panels. The XO or OX guide explains how to read handing from inside.

For ordering, Andersen says:

• Handed like the unit: handles, frame or jamb weatherstrip, and exterior keyed locks. On four-panel doors, the exterior keyed locks count as left-handed.
• Not handed: the panels, gliding insect screens, rollers, and the interlock weatherstrip between the panels. Andersen says the operating panels are drilled to work in either hand.
• The sill plug at the bottom of the interlock weatherstrip is ordered by the door's handing. Andersen says head plugs are universally handed and ordered by the door's age.

Write the handing on the door record card.

What you can check with the door in place

1. Keep it closed and locked. Andersen says an unlocked door's weatherstrip may decompress and push the sliding panel slightly away from the frame.
2. Clean the track. Andersen's method, at least once a year, is a soft-bristle brush with warm, mild soapy water, a clean-water rinse, and letting the track dry. It says not to lubricate the track, because the rollers will slide instead of roll; dry lubricant spray goes on the rollers, through the adjustment hole.
3. Check the gap, and adjust the rollers. Andersen's adjustment article points to step 18 of guide 0005309, done with the panel in the frame. Slide the panel open to a narrow gap at the side jamb. If the gap is not equal from top to bottom, remove the two threaded caps on the panel's bottom rail with a large flat-blade screwdriver. Turn the adjusting sockets clockwise to raise the panel or counterclockwise to lower it until the gap is even, then replace the caps. The guide warns that small parts such as hole plugs could be a choking hazard to young children.
4. Adjust the lock. On a two-panel door made from 2006 on, Andersen's step turns the latch receiver adjustment screw toward IN for a tighter fit or OUT for a looser one; on a four-panel door, Andersen's step adjusts lock engagement: turn the screw fully clockwise until snug, check the lock, and if it is too tight, turn it back counterclockwise in half-turn increments until it is snug. From 1994 to 2005, it removes the screws that hold the receiver in the side jamb, slides the pin, and retightens the screws. Before 1994, it turns the deadlock's screw: counterclockwise to tighten, clockwise to loosen. After a roller adjustment, Andersen says the latch receiver may need adjusting too.
5. Adjust the screen. Andersen puts its adjustment screw on the front of the screen panel from 1982 to 1991, and low on the side of the frame since. Counterclockwise lowers a screen sticking at the top; clockwise raises one sticking in the bottom track. The screen door guide covers a screen off its track.

Water on the sill. Andersen says the Frenchwood's weep holes sit under the stationary panel, out of sight; the sill leak guide covers what to check.

Parts that depend on the door

Rollers. Andersen says 400 Series gliding doors made from 1982 on use a tandem roller, with a design pressure version for panels 8 feet or taller, both from the Andersen Parts Store.

Locks. Andersen says the deadlock on a 400 Series door made from 1978 to 1993 is outdated and can be replaced with a current reachout lock and receiver, sold through the Andersen Parts Store, and that deadlocks on doors made from 1994 to 2005 can be upgraded the same way. For the Frenchwood it points to guides 0000127 and 0005197. Its hardware guide warns that incorrect installation may affect egress and home security. The mortise lock guide compares Andersen's lock documents with other makers'.

What this site leaves to a professional

• Inspecting or replacing rollers. Andersen says the panel must come out for both. It recommends replacing both rollers, and says it has service providers to install them.
• The bottom rail filler. Andersen says the fuzzy-pile weatherstrip under the operating panel can only be replaced with the filler, which takes the panel out. It says panels are extremely heavy, and points to a service provider.
• Head and sill plugs. Replacing them means removing the operating panel.

This site gives no steps for lifting or removing a panel. The roller repair page explains when adjustment is enough, and the alignment page covers a panel that sits crooked.

Where to take a repair

Andersen. For a door you already own, Andersen recommends its Identify Your Product tool first, and asks you to contact it from in front of the door. It says more than 900 factory-trained service providers take part in its annual training.

Replacing the door. The repair or replace guide sets out that decision, and the Dallas replacement guide covers the permit question.

What this page does not cover

• Prices. None of the Andersen documents opened gives a price for a part or for labor.
• Warranty terms. This page does not summarize Andersen's 400 Series limited warranty.
• The Frenchwood hinged door. Andersen also makes one; this page covers the gliding door only.

Asking about a repair

To ask about a Frenchwood gliding door in Plano, Allen, McKinney, or Frisco, use the contact page. Give the label number if you have it, the door's handing, and photographs of the label, the handle, and the glass logo. The operator reviews every inquiry and replies with the next step. Sending the form is not a booking.
