Ge dryer dde7100

It needs a new Humidistat Moisture Sensor. That is the part that senses how much moisture is in the garments and decides when to go to cool down cycle. That part is not used in Timed Dry.

Question edited for clarity.

Unlikely to be the control switch and more likely the Humidistat Control Sensor that decides if the clothes are dry or not.

It is a very complicated dryer.

I believe they just updated model number descriptions. The basic design of that humidifier hasn't changed much over the years. I would go to their website and look for the one that is simiar to your model and get the humidistat for it. They are pretty basic devices as far as what the humidistats do. 24v power and common

what i would do is make sure tha the hole for the wires that go to the humidistat is completely closed and that you are sensing the true humidity for the space also have the tech wire the so that the heat comes on instead of the ac for the de-hiumidification process.

I would think the timer is not used but a humidifier when on auto dry mode. Check the humidistat, should be either make or break contacts, open or closed.

Because they don't trust humidistats. Because they don't know what to expect a humidistat to do, or how accurate to expect the humidistat to be. Or, perhaps because they actually had experience with a humidistat that wasn't working properly.

replace the humidistat control

Either the humidistat is bad and not letting the unit cycle off, there isn't enough humidity in the air, or the condensor coils are too dirty.

sounds like a faulty humidistat, but may also be nearly out of freon. I have a GE unit that is also a portable air conditioner...works great for 5 years now...

You can test the humidistat fairly easily, using a volt-ohm meter. Just set the meter to RX1 scale and attach its leads to the humidistat's terminals. Rotate the humidistat's knob as far as it will turn in both directions. If the volt-ohm meter registers zero ohms through only part of the humidistat dial's range, the humidistat is working. If it registers zero through the entire range, it's broken and must be replaced. Dehumidifier Overflow Cutoff Switch Test- Using a volt-ohm meter, you can tell if the overflow switch works or not. Clip the leads to the terminals on the switch. Depress the bar or trip lever on the switch. If the meter's needle doesn't show continuity and no continuity as the switch is clicked back and forth, the switch is probably faulty and will need replacement.
