Dryer Stopped Working Completely — Start Here
Step 1 — Check the Circuit Breaker First
Electric dryers run on a 240V circuit made up of two 120V legs. When one leg trips — a partial trip — the control panel may still power on and display normally, but the motor and heating element get no power. The dryer looks like it should work but does nothing when you press start.
Go to your electrical panel and find the double-pole dryer breaker. Even if it looks like it is in the on position, reset it: flip it fully off, then firmly back on. A partial trip leaves the handle in a middle position that is easy to miss. If the breaker trips again immediately after reset, stop — there is a fault in the circuit or the machine that needs diagnosis before continuing.
Step 2 — Check the Door Switch
Every dryer has a door switch — a small button or plunger that the door depresses when fully closed, completing the circuit that allows the machine to start. If this switch fails, the dryer receives no signal that the door is closed and will not start under any circumstances.
Test it: open the door and press the switch manually with your finger while someone presses start. If the dryer starts with the switch manually depressed, the switch has failed or the door latch is not fully engaging it. On front-load machines, also check that nothing is caught in the door seal preventing full closure.
Step 3 — Check the Thermal Fuse
On many Maytag, Whirlpool, and Samsung dryer platforms, a blown thermal fuse cuts all power to the machine — not just the heating circuit. The dryer goes completely dead. This is different from the more common thermal fuse failure pattern (where the machine runs but does not heat) and is frequently missed because people do not associate a dead dryer with a fuse designed for heat protection.
If the breaker and door switch check out, a blown thermal fuse is the next most likely cause of a completely unresponsive machine — particularly if the machine was running normally until it suddenly went dead mid-cycle or at the end of a cycle.
Step 4 — Check the Start Button and Control Board
A failed start button — physically stuck, broken internally, or with a failed contact — produces a machine that powers on but does nothing when start is pressed. On digital control machines, a failed control board can produce the same symptom: display lights up, but no response to any input.
Start button failure is more common on machines with physical push buttons than touch controls. Control board failure is less common but more expensive — apply the 50% rule before authorising a board replacement on an older machine.
Step 5 — Check the Drive Motor
A failed drive motor produces a machine where power is confirmed, the door switch is working, and the thermal fuse tests intact — but the drum does not move when start is pressed. On some machines you may hear a brief hum when start is pressed before the machine cuts out. This hum-and-stop pattern is a strong indicator of motor failure or a seized drum that is overloading the motor.
Gas dryers still require 120V electrical power for the controls, igniter, and motor. A completely dead gas dryer is almost never a gas supply problem — it is an electrical problem. Work through the same sequence: breaker, door switch, thermal fuse, start button, motor. Confirm the machine has power before assuming anything about the gas supply.
The Diagnostic Sequence — Quick Reference
| Symptom | Most Likely Cause | First Check |
|---|---|---|
| No power at all — no lights, nothing | Breaker tripped or thermal fuse blown (all-power type) | Reset breaker first — off then on |
| Display lights up, nothing happens on start | Door switch, start button, or control board | Test door switch manually |
| Hum when start pressed, then silence | Motor failed or drum seized | Try spinning drum by hand — resistance means seized |
| Went dead suddenly mid-cycle | Thermal fuse (all-power type) or breaker | Thermal fuse continuity test |
| Powers on but no heat and no spin | Partial breaker trip | Full breaker reset — off then on |
When to Call a Technician
After the door switch and breaker checks — which any homeowner can do safely — further diagnosis involves testing components with a multimeter inside a live appliance. Thermal fuse testing requires accessing the rear panel. Motor testing requires disassembly. If the first two steps do not resolve the problem, a professional diagnosis is the right call — particularly since a dead dryer often has a single inexpensive cause that is quick to fix once confirmed.
