Ninestars trash can replacement parts

Ninestars sells replacement parts directly, through a parts section on its own US site. That is genuinely unusual at this price - most budget sensor brands have no parts path at all - and it means a can with a cracked battery cap or a dead sensor lid is often repairable rather than disposable. The catch is coverage: the catalog is organized by model code, several of the most common codes are missing from it, and a number of the listed parts were showing as sold out when we checked. So the honest answer is: find your model code first, check the catalog, and have a plan B.

The catalog uses three prefixes, and once you know them it reads itself. The number after the prefix matches the can's model code, not the capacity.

• CAP- is the battery compartment cover on the underside of the lid. It is the cheapest part in the catalog and by a distance the most commonly needed, because it is small, it is the only thing you remove regularly, and it goes missing. CAP-4, for example, is the cap for the DZT-80-4 and the WM-80-4.
• LID- is the complete sensor lid assembly: housing, infrared sensor, motor and gearbox in one unit. This is what you buy when the electronics have failed rather than the batteries. It is the expensive part - several times the price of a cap, and a meaningful fraction of a new can.
• RING- is the removable liner ring that clamps the bag to the rim and hides the overhang. Replaceable because it is plastic, it gets pulled on hard every bag change, and a cracked one stops the can holding a liner properly.

There is no catalog entry for the body, the inner bucket on models that have one, or the pedal on the step models. If one of those fails, the can is the part.

The list below is what Ninestars' US parts section showed on October 20, 2026. We are giving you the fitment and a price bracket rather than a number, because stock and pricing on a parts page move and a stale figure is worse than none. Check the live listing before you plan a repair around it.

Two things to take from that table. First, the caps are the part most likely to be available, which is lucky, because they are the part most likely to be needed. Second, several model codes that sell in large numbers - the DZT-50-9 oval sensor can and the WM-50-13 rectangular one among them - have no entry at all. If you own one of those, the official catalog is not your route.

This is the part worth reading twice, because it explains why the parts store exists in the shape it does. Ninestars' stated warranty covers the electronic mechanism of the lid only - the company names the computer chip, the motor, the gearbox and the electrical circuits. It explicitly does not cover the base of the unit, battery caps, liner rings or the inner bucket.

In other words, the two parts people most often need - the cap and the ring - are outside the warranty by design, which is precisely why they are sold as paid spares. That is not a scandal; it is consistent, and it is more honest than a brand that has no parts at all and tells you to buy another can. But it does mean a warranty claim will not get you a battery cover.

1. Proof of purchase is mandatory. A receipt, a completed warranty card or an online registration. No proof, no claim.
2. Authorized sellers only. Ninestars states that products bought from auctions, auctioneers and discount or closeout stores are not covered. A bargain from an unauthorized reseller is an uncovered can.
3. You need an RMA number before you ship anything. Contact support first; a package arriving without one is a package nobody can match to a claim.
4. Return shipping is on you. Ninestars prepays ground shipping on the replacement going out; getting the defective unit back to them is prepaid by the customer.
5. Liability caps at the purchase price. Stated plainly in the policy, and reasonable - but it means a long repair saga is never worth more than the can cost.

Weighed against the field, this is still a decent position. Glad has no parts catalog for its cans at all, and Sterilite handles lid replacement through a contact form rather than a store. A published policy with a stocked parts page beats both. The brand that does this best is Joseph Joseph, which stocks consumables and some hard parts and guarantees its Totem and Titan bins for three years - the full comparison is here.

The DZT-50-9 is the clearest example: a popular can, widely sold, and no official battery cap listed for it. The same is true of the WM-50-13. For a missing cap specifically there is a real aftermarket - several sellers make snap-in covers dimensioned to these models, and they do the only job a cap has to do, which is hold the cells against their contacts.

An aftermarket cover for the DZT-50-9, which is the gap in the official catalog most people fall into. Not OEM, and not warranted by Ninestars - but it is the difference between a working can and a dead one.

Confirm the code before you order. The covers for the DZT-50-9, the WM-50-13 and the DZT-80-4 are different shapes, and the listings for all three use similar wording. If you are not sure which can you have, the base is the place to look, and the battery compartment itself will tell you the cell size and count - which is worth knowing anyway, because Ninestars' own published battery specs contradict each other on at least one model.

For a failed sensor lid with no LID- part listed, there is no aftermarket equivalent - a lid is molded and wired to a specific body. At that point the question is economic rather than technical, and the answer is usually a new can.

Before you buy anything, run this list. Most of what gets diagnosed as a dead sensor lid is one of these, and all five are free.

• Replace all the batteries together, with alkalines. A fresh cell alongside two tired ones is the commonest cause of a lid that opens but will not close. Rechargeables at 1.2 V can be marginal for a board expecting 1.5 V.
• Clean the battery contacts. A green or dull contact is a bad connection. A pencil eraser or a dab of vinegar on a cotton bud, dried thoroughly, restores most of them.
• Wipe the sensor window. Cooking grease on an infrared eye reads as a permanent hand, and the lid sits open or cycles on its own. This is the single most common fault on these cans.
• Check the power switch. Every Ninestars sensor lid has one, and it gets knocked off during bag changes more often than anyone admits.
• Clear the lid frame. An overfull liner or a bag edge caught under the rim stops the lid seating, and the motor keeps trying. Touchless lid not opening is the full fault-finding order.

If the lid is doing the opposite - opening by itself, cycling, refusing to close - touchless trash can keeps opening covers that fault specifically, and touchless trash can replacement parts is the cross-brand version of this page, including who else actually stocks spares.

A battery cap is a trivially easy yes - it costs a fraction of the can and it takes seconds to fit. A liner ring is usually a yes for the same reason. A complete sensor lid is the decision that needs thinking about: at around a third to a half of what the can cost, you are rebuilding a budget appliance with the body, the hinge and the bucket all carrying the same years of wear as the part that failed.

Our rule of thumb is the same one we use on every can on this site: if the repair costs more than half of a replacement, replace. And if you are replacing, replace for the part that broke - if the sensor lid died twice, a step can has nothing in it to die. Step can versus touchless is that argument in full.

If the repair is not worth it, these are the two Ninestars cans we would buy again - the rectangular 13-gallon for a normal kitchen, the 80-liter XL for a household that outgrew one.
