The short answer
The usual answer on this unit is a restricted vent making a protection cycle, with moisture sensor bars coated with softener residue next. Neither is a board fault, and both are free to check. Most of this is cleaning rather than repair, and the page stops before any live terminal.
The symptoms, and their near misses
- A timed cycle works but an automatic one does not — That is sensing, and it is the single most useful observation on this page.
- The cycle runs on and on and never completes — The machine cannot reach the condition it is waiting for.
- NEAR MISS: no heat at all at any point — Read the heating page for this unit instead.
What it usually turns out to be, in order
- A restricted vent making a protection cycle — With airflow restricted, the machine overheats, a thermal protection opens, and the cycle either stops or runs cold for the rest of its length. It is the same root cause as a no-heat fault, caught earlier. First, and the whole order below follows from it: it is the root of most dryer faults of every kind, and it is the one that gets worse until it becomes a fire risk.
- Moisture sensor bars coated with softener residue — Automatic cycles measure the load through two metal strips in the drum. Second: it is the cause that explains the exact pattern of a timed cycle working and an automatic one failing, and it is free to fix.
- A lint screen sealed with softener film — A screen that looks clean can be sealed by a film that water will not pass. Third, once the two above are clean: it is invisible without a specific test, which is why it sits high on this list rather than being assumed clean.
- A timer or control board fault — A worn timer contact or a failed board gives a cycle that behaves differently every time. Last on purpose: the causes above produce the same behaviour for nothing, and this one needs a meter and a manual.
What to check first, second, third
- Run the dryer and feel the airflow at the outside vent — Weak air outside explains both a short cycle and an endless one.
- Run a timed cycle and see whether it dries the load properly — Timed working and automatic failing is the sensor, almost without exception.
- Hold the lint screen under a running tap — Water pooling on the mesh means the screen is sealed.
The checks you can make yourself
- Pull the machine out, disconnect the duct and clear it end to end, then check the outside flap opens — A brush on a rod does the job.
Tools: a vent brush, a vacuumAbout 45 min
- Wipe the two metal strips inside the drum with a cloth and a little white vinegar, then rinse and dry them — Use less softener afterwards, or dryer sheets more sparingly.

- STOP AT THIS POINT if the next step is inside the cabinet or on the gas train — Burners, valves and igniters are not owner work on any gas appliance.

Safety
Unplug the dryer or drop its breaker before a panel comes off, and close the gas valve at the appliance before you move a gas machine. If you smell gas: do not switch anything on or off, leave the building, and call the gas utility or emergency services from outside. Do not look for the leak yourself. Lint packed against a heat source is the real hazard in this appliance, which is why airflow is treated as urgent and not as maintenance.
Where an owner check ends
Call once the sensor bars are clean, the vent is clear end to end, the lint screen passes water and the door switch is sound, because what is left is the thermistor, the thermostat or the control. Call sooner if the machine overheats, smells scorched, or trips its breaker.

Scope of this page, and where to go for more
This page covers the Westbend dryer as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: thermistor resistance figures, timer part numbers, error code tables and any wiring detail, all of which differ by family and belong on the page for that family.
