The short answer
On a Danby dryer, a cycle that does not complete most often comes back to restricted airflow tripping a limit device mid-cycle. 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: load size defeating the cycle logic 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
- An automatic cycle ending after a few minutes with a wet load
- A cycle that runs far longer than its setting
- The machine stopping partway and needing start pressed again
- A cycle that will not advance past one stage
- An error indicator partway through
Ranked for a Danby dryer
- Restricted airflow tripping a limit device mid-cycle — Why this rank: A machine that overheats shuts its heat down and sometimes ends the cycle; the cycle fault is a symptom of the duct. — Owner checkable: true
- The wrong cycle or dryness level selected — Why this rank: Timed, automatic and delicate cycles behave very differently, and a machine on the wrong one looks faulty to whoever did not set it. — Owner checkable: true
- Cycling thermostat opening early — Why this rank: A drifted thermostat cuts the heat before the cycle logic expects it, which stretches or truncates the run. — Owner checkable: false
- Moisture sensor bars coated, so the cycle ends early — Why this rank: Automatic cycles measure conductivity across two bars in the drum; a softener film makes a wet load read as dry and the machine stops doing exactly what it was told. — Owner checkable: true
- Door switch dropping out during the cycle — Why this rank: A worn switch loses contact with vibration, which stops the machine at random points rather than the same one. — Owner checkable: true
Check in this order
- Disconnect the duct and check the whole run. — Because: It sits at rank 1 on this brand.
- Run a normal timed dry and compare against the automatic cycle. — Because: It sits at rank 2 on this brand.
- Note whether the drum feels less hot than usual. — Because: It sits at rank 3 on this brand.
- Wipe the sensor bars with rubbing alcohol and re-run an automatic cycle. — Because: It sits at rank 4 on this brand.
- Note whether it stops at random points. — Because: It sits at rank 5 on this brand.
Steps a homeowner can safely take
- Wipe the moisture sensor bars inside the drum with a cloth and rubbing alcohol, then re-run an automatic cycle. — Tools: rubbing alcohol, cloth
About 20 min
- Run a normal timed dry of the same load and compare — if timed works and automatic does not, the sensing is the fault. — Tools: none — Time: 1 cycle
- Note whether the machine stops at the same point every time or at random points; the two mean different things. — Tools: notepad — Time: 2 cycles
- Clean the lint filter and check the exhaust duct along its whole run and at the outside flap. — Tools: vent brush, screwdriver, flashlight
About 45 min
- Open and close the door firmly and listen for the switch to click; a switch that drops out gives random stops. — Tools: none
About 10 min
- Switch the breaker off for a minute, restore it and run a plain timed cycle from cold. — Tools: none
About 15 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
