# Electrolux dryer moisture sensor service

### Two metal strips, and a film beats them

The automatic cycles do not measure time or temperature — they measure conductivity across damp fabric, using two metal bars inside the drum opening. Anything that insulates those bars makes the machine believe the load is drier than it is, and fabric softener and dryer sheets do exactly that. It is a maintenance item that reads as an electronic failure, and this maker's own note on the code says plainly that the machine keeps working in the meantime.

What this involves

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 ordinary cause and it is free to fix

Clean the strips inside the drum opening

A little rubbing alcohol on the two metal bars. This is the whole repair often enough to try before booking anybody.

Run an automatic cycle and see whether it stops on its own

That test tells you whether the cleaning worked better than any measurement will.

Test the sensor and its harness if it stands

Say on the phone that timed cycles still work — it narrows the part before we arrive.

### Which cycles are affected?

Only the automatic ones. If timed cycles still dry correctly, that is a useful thing to tell us because it narrows the part before anybody arrives.

### Do I have to stop using dryer sheets?

No, but they will bring it back. Wiping the strips with a little rubbing alcohol every few months is the easier trade.
