Maytag Dryer Error Code F28
Moisture sensor open circuit
The control lost the signal from the moisture sensor bars inside the drum, so sensor-dry cycles can't tell when clothes are dry. Cycles run far too long or stop early. The same F28 appears on Whirlpool-built dryers. Fabric-softener film insulating the bars, or a broken sensor wire, are the common causes.
