Clothes dryer
Also called tumble dryer.
A heater, a motor, a belt, and a stack of thermal cutouts that exist because the heater is serious. Gas dryers have a burner instead of the element; do not improvise with gas valves.
A donor is the dead machine. The parts below are what is still worth removing from it. “Leave it” is a part that is physically in there and should stay in there: too dangerous, too worn, or only useful as part of a repair you are not doing.
Wall power goes through a switch, a one-time thermal fuse, and often a resettable thermostat, then the element. If you remove the fuse because it is open, the element can stay on after something else has already failed. That is how the donor caught fire the first time.
Why it is in the trash while the parts are not
No heat, which is often an open thermal fuse after a blocked vent, or a dead drum roller. The element may still be good. Find out why the fuse opened before you reuse either.
Before you open it
Do this while it is still unplugged, cool, and not leaking. Unplug. 240 V machines have both poles hot. Confirm dead. Let it cool.
Where the dead machine usually is
- Laundry and utility closet — In the house
- Bulk trash day — Curb
Electric dryers are 240 V in many countries. The cord is not a generic mains lead.
How it comes apart
Rear panel. The element is a can or an open coil. The thermal fuse is in the blower housing and looks like a small white or metal cartridge.
Tools: Nut driver, Meter.
Words on this page
- thermal fuse
- A one-time safety link that opens when it gets too hot and stays open. It is not a switch you can reset. Replacing it with wire removes the protection.
What to take
The table is the short version. The notes under it describe that part inside this machine, not only the general description.
| Part | Call | How many | How often | Where to look |
|---|---|---|---|---|
| Tubular heating element | Prize | 1 | usually | The heater can. |
| Nichrome wire | Worth pulling | 1 | sometimes | Open-coil models. |
| Thermal fuse | Worth pulling | 1–2 | always | Blower housing and heater. |
| Bimetal thermostat | Worth pulling | 1–2 | usually | Heater housing. |
| Single-phase induction motor | Worth pulling | 1 | usually | Blower and drum drive. |
| Timing belt | Bonus | 1 | always | Around the drum. |
| Bearing and bushing | Worth pulling | 2–4 | usually | Drum rollers. |
| Safety interlock | Worth pulling | 1 | always | Door. |
| NTC thermistor | Bonus | 1 | sometimes | Moisture or temperature probe on electronic models. |
Prize
Low ohms, high watts. Calculate from the plate.
The heater can.
Insulation-check to the frame.
Open sections are scrap. Leakage to the can is scrap.
Worth pulling
Bare wire on ceramic supports.
Open-coil models.
Do not let turns touch when you reuse it.
Brittle.
One-shot. A good one still reads shorted.
Blower housing and heater.
Do not replace an open fuse with wire.
Open is common, and it is evidence.
Cycling thermostat and a high-limit. They are different parts.
Heater housing.
Read the temperatures.
Good if it still clicks.
Mains motor, often with a centrifugal start switch.
Blower and drum drive.
Read the plate. Do not drop it; the switch is glass-fragile on some.
Good.
Plastic wheels with a bearing. They seize and squeal, which is often why the dryer was scrapped.
Drum rollers.
Take only the ones that spin freely, as a pattern.
Often the failure.
Mains switch.
Door.
Test it.
Good.
Bonus
A long flat belt.
Around the drum.
Glazed and stretched is normal at end of life.
Often tired.
A sensor, not a fuse.
Moisture or temperature probe on electronic models.
Calibrate.
Good.
