What a technician actually does
squealing or thumping every rotation (dryer: drum rollers or idler pulley) [S1]
high likelihood moderate $349 installed about 90 min
squealing or thumping every rotation a noise it never made before
The signature is the rhythm: a sound that arrives once per rotation is a rotating part, and on a dryer that is the rollers the drum turns on or the idler that keeps the belt tensioned. Both are early-warning parts rather than failures - they announce themselves long before the drum stops turning, which is why the source calls noise the most common way an appliance tells you something is going.
S1 publishes a completed-job median rather than a part price: $349 for drum rollers or an idler pulley, from its dryer noise repairs
loud screech at startup (dryer: worn drive belt) [S1]
high likelihood advanced $322 installed about 75 min
a noise it never made before squealing or thumping every rotation
A screech that belongs to the start of the cycle rather than the whole of it is a belt slipping on a pulley that has stopped turning freely, and the source's own price makes the point about this whole page: at $322 it is the cheapest entry in a table of eight, and it is the one that, left alone, turns into a drum that does not turn at all. The tell is that it is worst in the first seconds and quietens as the load gets moving.

banging or thumping at spin (washer: shock absorbers or suspension) [S1]
high likelihood advanced $367 installed about 150 min
banging when it spins a noise it never made before
The single most common noise repair in the source's washer records - 195 completed jobs - and the one whose timing gives it away: a washer that is quiet through the wash and starts banging only when the drum speeds up has lost the damping that holds the drum steady. The drum is not loose because it is broken; it is loose because nothing is resisting it, which is why the same fault shows up as violent shaking on the balance page.

rattling or grinding while draining (washer: drain pump with debris inside) [S1]
high likelihood moderate $381 installed about 90 min
rattling or grinding while it drains
The sound is tied to a phase rather than to the spin: a rattle or grind that appears only while the machine is pumping out means something is in the pump, and on a washer that is usually a coin, a bra wire or a small stone that has come out of a pocket. The source's own framing of this one is the useful part - caught early it is a cleanout, and caught late the impeller is chewed and the pump is replaced, which is the difference between opening the filter and paying for a pump.

clicking every few minutes (refrigerator: start relay failing to launch the compressor) [S1]
medium likelihood advanced $389 installed about 60 min
clicking every few minutes a noise it never made before
The one entry on this page that is a countdown rather than an annoyance: a relay that clicks, fails to start the compressor and clicks again a few minutes later is a relay on its way out, and when it stops trying the refrigerator stops cooling. The source's price is the cheapest repair in its refrigerator noise section, which is the argument for acting on this click rather than living with it - the failure it precedes is a sealed-system one.

buzzing or rattling from the back (refrigerator: evaporator or condenser fan motor) [S1]
medium likelihood advanced $422 installed about 90 min
a noise it never made before buzzing or rattling
Where the sound comes from decides this one: a buzz or rattle from behind the refrigerator is a fan, and which fan matters. The condenser fan runs whenever the compressor does and sits in the open at the back; the evaporator fan sits inside the freezer compartment and moves cold air into the cabinet, so when it stops the food suffers before the noise does. The source's price is the top of its noise table and still inside the band that makes repair the answer.

grinding mid-cycle (dishwasher: drain pump chewing glass or a fruit pit) [S1]
medium likelihood advanced $350 installed about 90 min
rattling or grinding while it drains
The same failure as the washer pump above with a different cause: a dishwasher pump grinds when broken glass or a fruit stone has reached it, and the source is specific about where those come from - a glass that broke in the machine, or a plate that went in without being scraped. It is the one noise on this page that means stop the cycle rather than note the sound, because the debris is being ground against the impeller while it runs.

loud droning or humming during the wash (dishwasher: circulation motor bearings) [S1]
medium likelihood advanced $374 installed about 120 min
a loud drone during the wash a noise it never made before
A wash that has always hummed and now drones is a motor whose bearings have gone, and the distinction the source draws is between the two pumps in a dishwasher: the drain pump empties the tub and is heard at the end, while the circulation motor drives the wash arms and is heard throughout the cycle. A drone that runs for the whole wash is the second one, and it is the noise that most often precedes a wash that no longer cleans.

Repair or replace?
Treat a new noise as a diagnosis rather than a decision, because the same part is rarely the answer twice: match the sound to the row in the table, and the phase it happens in narrows it further - once per rotation is a rotating part, at startup only is a belt, only while draining is a pump, only when the drum speeds up is suspension, and a click every few minutes on a refrigerator is a relay about to stop trying. Every one of those repairs lands between $322 and $422, which is why the source can call noise the cheapest early warning an appliance gives. [S1]
- Typical completed repair: $320–$380 [S1]
- Comparable new unit: $550–$1,400 [S1]
- Planning life used for the decision: 12 years
- The comparison is not repair against replacement on this page, it is a $322-422 repair against a part that costs four figures once the noise is ignored: a belt left screeching takes the motor with it, a relay left clicking ends in a sealed system, and a pump left grinding ends in a pump plus the labour to reach it twice.
this hub crosses appliances, so no single replacement figure applies; the band here is the narrowest published comparison for the machines in the table - a new dryer from $550 and a new washing machine from $700 to $1,100 - and the per-appliance guides carry their own replacement bands and expected lives
