The short answer
A new noise from the FDG line nearly always comes from something the drum turns on — rollers, an idler pulley, the blower wheel — rather than from the motor itself. On this page the idler leads: a squeal that rises with the motor rather than the drum has one likely source. The sound and when it happens name the part: a thump once per drum revolution, a squeal that rises with speed and a rattle only on start-up are three different jobs.
What an owner actually observes on the FDG line
- A rattle or ticking that comes and goes — Coins or a zip pull in the blower wheel, or an object trapped in the lint duct.
- A scraping or rubbing from the front of the drum — Worn drum glides or a felt seal that has given up, letting the drum sit down on the bulkhead.
- NEAR MISS — the dryer hums but the drum does not turn — That is a broken belt or a seized part, not a noise fault. Stop the machine: running it makes the damage worse.
The ranking for the FDG line, likeliest first
- The idler pulley or the belt — Ranked first because the idler runs at high speed on a small bearing and squeals long before it fails. A squeal that follows the motor rather than the drum is this part almost by definition.
- Drum support rollers worn or dry — A flattened or dry roller thumps and then rumbles. It ranks here because reaching it means the cabinet comes apart, so cheaper checks come first.
- The load, the level or something in the drum — An unbalanced or tangled load knocks against the drum; a dryer on three feet drums against the floor. Both are free to correct.
- An object in the blower wheel or the lint duct — Last on this ordering, and worth a look anyway: it is the one fault that costs nothing but time to clear.
The diagnostic order, and the reason for it
- First — listen for whether the pitch follows the motor or the drum — Squeals that rise with motor speed belong to the idler and belt; anything tied to the drum turn does not.
- Then — spin the drum by hand with the power off and feel for a catch — Reach in and turn the drum slowly. A flat on a roller can be felt as a regular catch long before it can be heard clearly.
- Only then — run the machine empty for a minute and listen — An empty drum removes the load as a variable. While it is stopped, check the machine sits solid on all four feet.
- STOP here if the next check needs a panel off or a meter on live terminals — Everything above can be done with nothing dismantled; past it the checks need test equipment.
Read this before any panel comes off
Safety
Unplug the dryer or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off, and the heater terminals stay live whenever the machine is connected. If yours is a gas model and you smell gas: do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside; do not look for the leak yourself. Never run the machine with the vent disconnected into the room, and never bypass a thermal cut-out to get a load finished.
When it stops being an owner job
Call when the noise is a grind that worsens with running time, when the drum has free play at the front, or when the belt has to come off to find the source. On the FDG line, call rather than continue if the cabinet has to be opened to reach the rollers. Stop and call immediately if the noise comes with a burning smell or with a scorch mark anywhere on the load — that combination is a lint and heat problem, not a bearing.
