- “Automatic cycles wrong while timed cycles are right — that is the sensor”
- “E 4, and the maker's own note says the machine keeps working”
- “Softener film across the strips is the usual cause and it is free”
Symptom
Electrolux dryer stops before the load is dry
That combination is the moisture sensor, and this maker publishes it as E 4 with unusually generous wording: the dryer keeps working and what you lose is the automatic programs. The sensor is a pair of metal strips inside the drum opening reading the resistance across damp fabric, and the commonest reason they stop reading is a film of fabric softener rather than a failed part.

Three ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
Softener film on the sensor strips
It insulates them, the reading goes high, and the machine concludes the load is dry when it is not.

The load is too small to touch the sensor
A single item tumbling can miss the strips entirely. Not a failure, and it explains intermittent complaints.

The sensor or its harness has failed
The genuine repair, and telling us that timed cycles still work narrows the part before we arrive.

In five minutes
Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
Clean the strips
Rubbing alcohol on a cloth. This is the whole repair often enough to always try first.
-
02
Test with a normal-sized load
A very small load genuinely does confuse an automatic cycle.
-
03
Confirm timed cycles are unaffected
If timed cycles are also wrong, this is not the sensor and the diagnosis moves to heat and airflow.
How it shows up
What people describe when they call
A shortcut
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem before anybody opens anything, which is why it is worth photographing before it clears.

About Electrolux dryer stops before the load is dry
What to do in the next ten minutes
Find the two metal strips inside the drum opening and wipe them with a little rubbing alcohol. Run an automatic cycle and see whether it stops on its own at the right point. Use timed cycles in the meantime — the machine still works.
What the automatic cycles actually measure
Not time, and not temperature — conductivity. Damp fabric conducts; dry fabric does not. Two metal strips in the drum opening measure the resistance across whatever touches them, and the control stops the cycle when the reading says dry. Anything that insulates those strips — softener, a build-up of detergent residue, a coating from dryer sheets — makes the machine believe the load is drier than it is. It is a maintenance item that reads as an electronic failure.

Before you book
Questions about Electrolux dryer stops before the load is dry
Should I stop using dryer sheets?
You do not have to, but they are the cause of this and they will bring it back. Wiping the strips every few months is the easier trade.
It over-dries rather than under-dries.
Same sensor, opposite reading, usually a harness or connection problem rather than a film. Worth booking, because over-drying is hard on fabric and on the machine.
