# When a Kenmore Dryer Needs Two Cycles, It Is Usually the Duct

## Why is my Kenmore dryer not drying: the machine is telling you about air

Here is the fact that settles most of these calls before anybody opens the machine. **All three companies that built these dryers publish a warning for restricted airflow.** A Whirlpool-built 110 shows AF and Whirlpool's own wording names a clogged lint screen or vent. An LG-built 796 shows a duct-block warning with a number attached that indicates roughly how blocked it is. A Frigidaire-built 417 belongs to a family whose own alarms-and-codes page is published with nothing in it, so that machine simply takes longer and says nothing.

Three separate engineering teams, three separate control systems, and two of them thought this problem common enough to give it a dedicated message. That is not a coincidence, and it is not a sales line.

## Two tests, both free, both conclusive

**The hand test.** Start a cycle and go outside to the vent hood. Strong warm push, flap lifted: the duct is fine and the problem is elsewhere. Trickle, flap barely moving: you are finished diagnosing.

**The water test.** Take the lint screen out and rinse it under a tap. Water should go straight through. If it beads up and sits there, the mesh is sealed with fabric-softener residue — invisible, gradual, and it strangles the machine on every load. Scrub it with warm soapy water and a soft brush.

Between them these two tests explain the majority of dryers in this county that need two cycles, and neither costs anything.

## Why it is worse here than the manual assumes

Long, flat runs through single-story houses, because that is how they were built. Humid intake air, so lint packs into a mat instead of blowing along. A flap outside exposed to weather twelve months a year, which lint eventually props open so that damp outdoor air drifts back down the duct between loads.

None of that is exotic. It simply means the cleaning interval printed in a manual written for average conditions is the wrong interval for this address.

## The protective device is a message, not a part

A dryer that has stopped heating altogether has usually had a thermal cut-out open. That is protection working correctly: the housing got hotter than it should, and the device opened before anything worse happened.

The part is cheap and fitting one gives you a working dryer and exactly the same machine you had before. The thing that overheated it is still in the duct, and the next cut-out opens a few months later. This is why we will not quote that repair without the vent — not to add a line to the bill, but because the alternative is selling the same job twice.

## Four things that mean stop today

Appliance fires are rare, and this page is not written to frighten anybody. That is exactly why these four need to be somewhere they cannot be skimmed.

A **burning smell** while the machine runs. Switch it off at the breaker and leave it off.

**Scorch marks** on the laundry, or clothes coming out hot enough to be uncomfortable to hold.

**A flap outside that does not open at all** while the dryer runs, which means the whole exhaust is going somewhere it should not.

**A cut-out that has opened twice.** Once is a warning. Twice is the duct telling you it was never cleared.

Everything else on this page can wait for a convenient day. Those four cannot.
