Direct answer
For the Samsung DV42H5000 dryer, match the sound to drum speed, warm-up and load before replacing parts. First, run empty briefly, then with several towels.
What this covers
- Samsung DV42H5000 dryer (DV42H5000*)
- Samsung dryer; the DV-prefix model number alone does not state electric versus gas — check the rating plate or full model suffix before applying either supply's diagnosis.
- The specific fault this record addresses: makes squealing, thumping, scraping or rattling noises
What it does not cover
- ×The same symptom on a different Samsung product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
A foreign object (coin, button, underwire) is loose in the drum
What separates it A rhythmic thump or clank that occurs once per drum rotation, present with any load and gone when run completely empty.
How to confirm Run empty briefly — if the sound disappears, check pockets and the drum interior/perforations for a trapped object.
- 2
A worn drum support roller or glide bearing
What separates it A rumbling, squealing or rhythmic thumping sound present even on an empty run, often worse when cold at the start of a cycle and sometimes improving slightly as things warm up.
How to confirm This is a wear part reached by removing the drum, and is a service repair rather than an external fix.
- 3
The blower wheel has debris or has cracked
What separates it A rattling or scraping sound tied to airflow rather than drum rotation speed — it may vary independently of how fast the drum is turning.
How to confirm Requires opening the blower housing, normally a service task.
- 4
The felt drum seal has worn through
What separates it A squealing or scraping sound specifically where the front or rear drum edge contacts the bulkhead, often worsening gradually over months.
How to confirm Visual inspection with the front panel removed shows visible wear or a gap in the seal felt.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the sound is present on an empty run — this separates a foreign object (disappears empty) from a mechanical wear part (present regardless of load).
- Whether the sound's timing matches once per drum rotation, matches the blower/airflow independent of drum speed, or is constant.
- Whether the sound has been present since the dryer was new or developed gradually.
Run the dryer briefly empty to isolate a foreign object
ReversibleIf the noise disappears, inspect the drum interior and perforations rather than any mechanical part.
Check pockets and load hardware
ReversibleZippers, buttons, underwire and coins are the most common cause and the easiest to rule out first.
Arrange service for a confirmed mechanical part (roller, bearing, blower or seal)
ReversibleThese require the cabinet or drum to come apart and are not accessible from outside the machine.
Confirm quiet operation through a full warm-up and cooldown cycle
ReversibleSome wear sounds vary with temperature, so a short test alone can miss them.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- DV42H5000*. Samsung dryer; the DV-prefix model number alone does not state electric versus gas — check the rating plate or full model suffix before applying either supply's diagnosis.
- Fuel — confirm ELECTRIC or GAS
- This entry series came in electric (DV42H5000EW) and gas (DV42H5000GW) — check the suffix. Electric no-heat = element/240V half-breaker/thermal fuse; gas no-heat = igniter/valve coils/flame sensor/gas supply.
- Venting
- A vented dryer — clogged lint screen or blocked duct causes long drying and overheating. Clean both regularly.
- Feature tier
- An older entry Samsung dryer with Sensor Dry; typically no Wi-Fi, so a long cycle is airflow or a mixed load, not a smart feature.
- Symptom boundary
- This record covers Samsung DV42H5000 dryer when it makes squealing, thumping, scraping or rattling noises. A different symptom on the same hardware, or this symptom on a different Samsung product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Metal-on-metal grinding, a hot rubber smell, or a drum that has visibly stopped turning smoothly means stop and unplug rather than continuing to run test loads.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Samsung Support publishes this as "Samsung washing machine information and error codes". Samsung's own washer troubleshooting and error-code article; covers filling, draining, spin and unbalanced-load conditions. What that article does not carry is the model boundary — it is written for a product line, and DV42H5000* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.

Common follow-ups
My older Samsung DV42H5000 isn't drying well.+
Start with airflow regardless of fuel: clean the lint screen every load and clear the exhaust duct — a blocked vent is the top cause of poor drying on any vented dryer. If there is no heat at all, check whether yours is electric or gas: electric points to a half-tripped 240V breaker or the element, gas to the igniter and valve. Cleaning the moisture-sensor bars also helps if Sensor Dry is ending cycles early.
There's a thumping sound once per rotation, only with certain loads.+
Run the dryer briefly empty — if the sound disappears, check pockets, buttons and the drum interior for a loose or trapped object rather than assuming a mechanical fault.
The dryer squeals even when empty, worse when it's cold.+
That pattern — present without a load, worse at startup — points to a worn drum support roller or bearing rather than something loose in the drum. It's a wear part reached by removing the drum, a service repair.
Does this answer apply to every Samsung model?+
No. It is scoped to DV42H5000*. Samsung dryer; the DV-prefix model number alone does not state electric versus gas — check the rating plate or full model suffix before applying either supply's diagnosis.
What should I record before troubleshooting squealing or thumping or scraping?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing squealing, thumping, scraping. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Stop for scraping metal, smoke, hot rubber or a seized drum.
