# Dryer error code E 4

### What E 4 means on this make

The moisture sensor has stopped reporting, so the dryer no longer knows when the load is dry. The maker’s own wording is the important part and it is unusually generous: the machine keeps working. Automatic cycles are what you lose — the ones that stop when the clothes are done — and timed cycles carry on exactly as before. The sensor itself is a pair of metal strips inside the drum that read the resistance across damp fabric, and the commonest reason they stop reading is a film of fabric softener across them rather than a failed part.

### The other ways this one is printed

E 4 · E4

The same condition is printed differently on different panels of the same make, and every spelling the maker publishes for it is above. Whichever of them you searched for, this is the right page.

### Where this appears, and why not to clear it

On the appliance’s own display, as a short single code — a letter and a number, or two letters. Nothing alternates and nothing arrives in halves on this make, so what the panel shows is the whole of it. Photograph it before you cut the power. This maker’s own answer to most of these is thirty seconds at the breaker, and that is worth following once — but a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again.

### What to do about it

- Keep using timed cycles. The maker says the machine still runs, and it does — this is a lost feature rather than a dead dryer.
- Wipe the two metal strips inside the drum opening with a little rubbing alcohol. Softener residue across them is the ordinary cause and it is free to rule out.
- Run an automatic cycle afterwards and see whether it stops on its own.
- If the code stands after cleaning, the sensor or its harness is the visit — and say on the phone that timed cycles still work, because it narrows the part before anyone arrives.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 912-9018](tel:+13059129018) and describe what the panel is doing before booking anything.

Humidity Sensor Failed. Your dryer will complete the current cycle and you can still operate manual cycles. If error code continues, schedule service.
