# Frigidaire dryer moisture sensor service

### The bars in the drum, and what confuses them

Automatic cycles work by touching the load: two metal strips inside the drum read how wet the clothes are as they tumble past. When they stop being able to, the machine either stops with the load damp or runs to maximum every time, and the cause is often a film rather than a failure. Fabric softener and dryer sheets leave a residue on the bars that insulates them, and in hard-water territory so does detergent carried over from the wash. Cleaning them is sometimes the whole repair.

What this involves

Cycles that end damp or never end at all point at the sensor

Fabric softener film is the usual cause, not a failed part

Often a clean rather than a repair — and we will tell you that

Clean the sensor strips

Fine abrasive pad and alcohol. This alone fixes most of these calls.

Test the reading wet and dry

A meter across the strips with a damp cloth, which proves whether the sensor is being read at all.

Check the harness and the control

A sensor that reads correctly and is ignored is a wiring or a board problem.

Compare timed and automatic cycles

A machine that dries perfectly on a timed cycle has a sensing problem, not a heating one.

Advise on softener use

Because the film comes back, and knowing that is worth more than the visit.

### Can I clean the sensor bars myself?

Yes, and it is worth trying before booking anything. Rubbing alcohol on a cloth, both strips, with the machine unplugged — if the automatic cycles come back, you have found it.

### Should I just use the timed cycles instead?

It works, and it costs you the thing the sensor was for. A timed cycle overdries the light loads and underdries the heavy ones, and overdrying is what wears clothes out.
