The short answer
On a Danby dryer, a refusal to start most often comes back to no power, or one leg of the supply lost. Danby is a Canadian maker that specialises in compact, portable and apartment-scale appliances, so its units end up in garages, basements, dorms, offices and second kitchens far more often than in a fitted main kitchen. The brand moves one thing in particular: no power, or one leg of the supply lost ranks higher here than it otherwise would. The first two checks below are owner work and need no tools beyond what is already in the house.
What you observe
- Nothing happens when start is pressed
- The panel lights but the drum will not turn
- A hum from the machine with no movement
- The machine stops the moment start is released
- It ran, stopped, and will not restart while warm
Ranked for a Danby dryer
- No power, or one leg of the supply lost — Why this rank: A dryer runs from a heavy circuit; a fully dead machine is a supply question, and losing one leg gives a machine that tumbles without heat rather than one that is dead. — Owner checkable: true
- Door switch not proving closed — Why this rank: No dryer will run with the door unproven, and a switch plunger that has worn or a door not latching fully is the most common single cause of a dead-but-powered machine. — Owner checkable: true
- Thermal fuse opened — Why this rank: On many machines the fuse is in the motor circuit, so an airflow overheat leaves the whole dryer completely dead rather than merely cold. — Owner checkable: false
- Control lock or a delay start set — Why this rank: Both refuse a start by design and both are easy to set by accident. — Owner checkable: true
- Start switch or motor start winding failed — Why this rank: A hum with no rotation is the signature of a motor that cannot get turning, and it is a distinct fault from a dead machine. — Owner checkable: false
Check in this order
- Check the breaker fully off and on, and confirm the plug is fully seated. — Because: It sits at rank 1 on this brand.
- Open and close the door firmly and listen for the switch to click. — Because: It sits at rank 2 on this brand.
- Note whether the machine had been running hot or slow before it died. — Because: It sits at rank 3 on this brand.
- Look for a lock or delay indicator and clear it. — Because: It sits at rank 4 on this brand.
- Listen for a hum when start is pressed. — Because: It sits at rank 5 on this brand.
Steps a homeowner can safely take
- Switch the breaker fully off, wait a minute, and switch it fully back on — a partial trip does not always look tripped. — Tools: none
About 10 min
- Open and close the door firmly and listen for the door switch to click; try holding the door pressed shut while you press start. — Tools: none
About 10 min
- Look for a control lock or delay indicator on the panel and clear it. — Tools: owner guide if available
About 10 min
- Press start and listen: a hum with no rotation is a very different fault from complete silence, and it is the key thing to report. — Tools: none
About 5 min
- Unplug the machine, open the door and turn the drum by hand — almost no resistance suggests a broken belt. — Tools: none
About 10 min
- Confirm the machine is plugged directly into its own receptacle with no extension cord. — Tools: none
About 10 min
- Stop condition: Stop at the first step that would require a meter on live terminals.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Nothing on this page asks you to work at a live terminal, and none of it asks you to defeat a door interlock or a safety switch — those exist to stop the machine running in a state that can injure you, and a machine that will not run with its door open is working correctly. If a breaker trips twice on the same operation, leave it off: a repeat trip is a fault to be found, not a nuisance to be reset. Stop at the first step that would need a meter on live terminals. unplug-before-service branch-circuit-15-20a
Owner fix or service call
The breaker is confirmed on and the machine is completely dead You hear a hum with no rotation The drum turns by hand with no resistance, which suggests a broken belt The machine died after running hot or slow — that combination points at a thermal device and an airflow problem
