Dryer won't start
Often a tripped breaker, or a door switch that no longer tells the dryer the door is shut.
Before the motor starts, power has to reach the dryer and the door switch has to report the door shut. Then pressing Start sends the signal through the start switch. On many designs the thermal fuse or a belt switch sits in that same path. When any link fails, you press Start and nothing happens. What you hear, and what happened just before, narrows down which link it was.
Nothing lights, nothing responds
Start at the breaker. A fully dead dryer usually has a power problem rather than a failed part inside: a tripped breaker, or a burnt cord or outlet. Scorching at the plug or outlet is a reason to leave it alone and call.
Power, but no start
If the drum light or display comes on but pressing Start gives no hum and no click, the motor isn't being told to run. The door switch is the most common reason. Most dryers won't start unless it reports the door shut, and a broken switch or strike makes the dryer think the door is open. You normally hear it click as the door closes, and some displays say outright that the door is open. If the door side checks out, the start switch is next. Its contacts wear, and the giveaway is a dryer that runs only while you hold the button in.
What happened right before it quit matters too. On many Whirlpool and Kenmore designs, a switch held closed by the drive belt cuts the motor when the belt breaks, so a dryer that went completely dead right after a thump often has a snapped belt inside. On models where the thermal fuse sits in the motor circuit, a fuse blown by overheating stops the whole dryer. If drying had been getting slower before it quit, a blocked vent probably overheated it, and the vent has to be cleared or the new fuse blows too.
If you hear a hum but the drum doesn't move, that's a different fault: the motor has power and can't turn, which points at the belt or the motor.
On the visit, our technician checks the power coming in first, then tests the door switch, start switch, thermal fuse and belt switch in turn, so we replace the part that's actually stopping it.
What it usually turns out to be
- Cleaning or upkeepTripped breaker or no powerIf nothing lights or responds, check the breaker before suspecting any part. A burnt plug or outlet can also cut the power.
- PartDoor switchThe dryer won't run unless this switch reports the door shut. No click when you close the door, or a door-open message on the display, points here.
- PartStart switchIts contacts wear out. Pressing Start gives no hum and no click, or the dryer runs only while you hold the button in.
- PartBroken-belt safety switchOn many Whirlpool and Kenmore designs, a switch held closed by the belt cuts the motor when the belt snaps. A dryer that went completely dead right after a thump often has a broken belt inside.
- PartThermal fuseOn models where it sits in the motor circuit, a fuse blown by overheating stops the dryer from starting at all. A history of slow drying points at the blocked vent that blew it.
Try this first
- Check the breaker. Electric dryers use a double breaker, and one half can trip.
- Close the door firmly and listen for the door switch to click.
- Press and hold Start for a moment, and tell us if it only runs while you hold it.
Stop using it and call now if
- The breaker trips again as soon as you reset it.
- Scorch marks or a burnt smell at the plug or outlet.
