Why won’t my Simpson dryer door stay closed?
On a Simpson vented dryer, the door is held shut by a small plastic catch that clicks into a sprung bracket built into the cabinet. When you push the door closed, the catch (also called the striker) snaps into the bracket, the bracket grips it, and that light pressure holds the door tight against the seal.
Two things happen at once when the door is properly latched. First, the door stays physically shut so hot air stays inside the drum. Second, the closed door presses against the door switch, which tells the dryer it is safe to run. No closed door, no running dryer.
The catch and the bracket are both plastic, and plastic gets a hard life inside a dryer. Every cycle it goes through heat, then cools down, dozens of times a week for years. Over time that heat cycling makes the plastic brittle. Eventually the little arms on the catch, or the spring fingers in the bracket, fatigue and crack.
Once the plastic is worn or snapped, the catch no longer grips the way it should. You’ll notice the door popping open partway through a cycle, or refusing to click shut at all no matter how firmly you push it. Sometimes the door will hold if you lean on it, then drop open the moment you walk away. That is worn plastic, not a fault with the motor, the element or the timer.
It is one of the most common Simpson dryer complaints we see, and it is also one of the cheapest to put right. The whole catch, striker and bracket assembly is a single low-cost part, and no special tools are needed.
Is it the catch or the door switch?
Because a Simpson dryer won’t start unless the door is closed, a worn catch and a faulty door switch can look like the same problem: you press start and nothing happens, or the dryer stops mid cycle. Here is how to tell them apart before you spend a cent.
Start by looking at the door itself. If the door will not physically stay shut, if it pops open or springs back when you close it, the problem is mechanical and the catch or bracket is the culprit. A door switch fault does not stop the door from latching; the door still clicks shut normally, it just doesn’t trigger the machine.
Next, close the door slowly and watch and listen. A healthy catch gives a firm, positive click and the door sits flush against the cabinet with no gap. If you get a soft, sloppy feel, a rattle, or you can see the catch is cracked or a piece has broken off, that is your answer.
If the door clicks shut firmly and stays shut, but the dryer still won’t start or cuts out mid cycle, then the catch is doing its job and you should look at the door switch (or micro switch) instead. That is a different part and a different repair.
A quick rule of thumb: door won’t stay shut = catch and striker; door stays shut but machine is dead = door switch. In practice the worn catch is far more common, and because it’s the cheaper of the two, it’s the sensible first thing to replace. If in doubt, run the part finder quiz and it will point you to the right component for your model.
Which door catch kit fits my Simpson dryer?
The part you need is the Simpson clothes dryer door catch, striker and bracket assembly, part number 0030377068 (our reference 0201). It’s a genuine Simpson component and it comes as a complete assembly, so you replace the catch, the striker and the bracket together as one job rather than trying to source worn pieces separately.
This assembly fits a long list of Simpson vented dryer models. Check your model sticker, which is usually on the door opening rim or the back of the machine, and match it against the list below.
| Part number | Fits these models | Genuine/Compatible | Price | Buy |
|---|---|---|---|---|
 Door catch, striker & bracket assembly (Oz ref 0201) | 39B360P, 39B365S, 39B450P, 39B455S, 39B506SE, 39D361P, 39D456S, 39D505SR, 39P350J, 39P350K, 39P350L, 39P361E, 39P362E, 39P450J, 39P450K, 39P450L, 39P452E, 39S355J, 39S367E, 39S455J, 39S455K, 39S455L, 39S456E, 39S457E, 39S500J, 39S500K, 39S500L, 39S505E, 39S550J, 39S550K, 39S550L, 39S555K, 39S555L, DC350S, DC460S, DE452B (plus sub-variants such as 39B360P000/100/110) | Genuine | $10.39 | Buy now |
If your Simpson model number begins with 39 and it’s a front-loading vented dryer, there’s a strong chance this is your part. The 39B, 39D, 39P and 39S families are all covered, along with the DC and DE series shown above, and the various sub-variants that share the same door hardware. If your exact model isn’t printed here, don’t assume it won’t fit: many Simpson dryers built across this period used the same door catch assembly even where the model code differs by a digit or two. The safest check is to read your model sticker and compare it to the list, or let the part finder confirm it for you.
Because this is a genuine Simpson assembly rather than a generic copy, the catch geometry and spring tension match the original exactly, so the door closes with the same firm click it had when the machine was new.
How to replace the door catch, striker & bracket
This is a low-risk mechanical repair with no wiring involved, and most people have it done in around fifteen minutes. You’ll need a Phillips screwdriver and, sometimes, a flat blade to gently release a clip. Take your time and don’t force any plastic.
- Isolate the dryer from power. Turn it off at the wall and unplug it, or switch off the isolation point if it’s a fixed connection. Even though this is a mechanical job with no live parts, always work on an appliance that is disconnected from power.
- Open the door and inspect. Look at the catch on the door and the bracket in the cabinet opening. You’ll usually see where the plastic has cracked, worn smooth or lost a piece. This confirms you’re replacing the right part.
- Remove the old catch from the door. The door catch is held by one or two screws, or by moulded clips. Undo the screws (or gently ease the clips) and lift the old catch out. Keep the screws safe.
- Remove the old striker bracket from the cabinet. The sprung bracket sits in the door frame opening. It’s usually held by a screw or a clip at the top and bottom. Release it and take out the worn bracket. Note which way up it sits before you remove it.
- Fit the new bracket. Place the new striker bracket into the cabinet opening the same way the old one came out, and secure it with the screw or clip. Make sure it sits square and doesn’t rock.
- Fit the new catch to the door. Line up the new catch in the same position as the old one and refit the screws or press it home until the clips seat. It should sit flush with no play.
- Test the latch by hand before powering up. With the dryer still unplugged, close the door a few times. You want a firm, positive click and a door that stays shut on its own with no gap around the seal. If it feels loose, check the bracket is seated correctly.
- Reconnect power and run a short cycle. Plug the dryer back in, start a short cycle and confirm the door stays closed and the machine runs from start to finish without popping open.
If the door now clicks shut firmly and the dryer runs through without stopping, the repair is complete. If the door latches but the machine still won’t start, the door switch is the next thing to check.
When to call a technician vs DIY
Replacing the door catch, striker and bracket is one of the most DIY-friendly repairs on a Simpson dryer. There’s no wiring, no gas, and no dismantling of the drum or heating element. If you can use a screwdriver and follow the steps above, this is well within reach for most people, and at $10.39 for the part it’s a genuinely cheap fix.
The one rule that always applies: isolate the dryer from power before you start. Turn it off at the wall and unplug it. It’s a mechanical job, but working on any unplugged appliance is simply good practice and keeps everyone safe.
Consider calling a qualified technician if the door still won’t stay shut after you’ve fitted the new assembly (which can point to a bent door, a worn hinge or a cabinet that’s out of square), if the door latches firmly but the dryer still won’t start or trips the power (that moves into door switch or electrical territory), or if you’re not comfortable handling the repair yourself. There’s no shame in that, and a licensed appliance tech can fit the same part quickly.
For a straightforward worn catch, though, the DIY path saves you a call-out fee and gets your dryer running the same day the part arrives.
Frequently asked questions
Why does my Simpson dryer stop mid cycle?
The most common cause is a worn door catch. When the plastic catch or bracket is fatigued, the door can drift open partway through a cycle. As soon as the door isn’t fully closed, the door switch opens and the dryer stops. Replacing the catch, striker and bracket assembly (part 0030377068) usually fixes it.

You need the door catch, striker and bracket assembly, part number 0030377068 (our reference 0201). It’s a genuine Simpson part that comes as a complete kit, so you replace all three worn components together. It’s priced at $10.39 with same-day dispatch from our Sydney warehouse.
How do I know if it’s the catch or the door switch?
If the door won’t physically stay shut, or pops open, it’s the catch and bracket. If the door clicks shut firmly and stays closed but the dryer still won’t start, it’s more likely the door switch. Worn catches are far more common and cheaper to replace, so they’re the sensible first check.

Yes. Part 0030377068 is a genuine Simpson door catch, striker and bracket assembly. Because it’s genuine rather than a generic copy, the catch geometry and spring tension match the original, so the door closes with the same firm click it had when new.
