The MED8630 uses Advanced Moisture Sensing Plus: in a sensor cycle the Sensing light shows the moisture sensor is working, the display shows an estimated time and the dryer shuts off when the load reaches the selected dryness. Maytag's help says a sensor cycle can end early if the load is not contacting the sensor strips: level the dryer, use Timed Dry for very small loads and change the dryness level. The Check Vent light, available on sensor cycles only, warns of poor airflow that also stretches sensor cycles.
Differential
Likely causes of “Maytag dryer sensor cycle ends too early or runs too long”, and how to tell them apart
- 1
The load is not touching the sensor strips
What separates it Sensor cycles end early with damp items because the load is not touching the sensor strips
How to confirm Level the dryer and use Timed Dry for very small loads
- 2
The Check Vent light shows poor airflow
What separates it The light comes on early and stays on for the whole cycle
How to confirm Clean the lint screen and vent, then run another sensor cycle
- 3
A dryness level too low for the load
What separates it Heavy items finish damp because the dryness level is too low for the load
How to confirm Raise the Dryness level or use More Dry with High temperature
- 4
A room colder than 45 degrees F
What separates it The dryer does not shut off at the end of automatic cycles
How to confirm Move the dryer to a warmer room or wait until the room warms
Before you touch a setting
Record this first — changing settings destroys the evidence
- The cycle, temperature and dryness level and whether the Sensing light was lit
- Whether the Check Vent light came on and when
- The load size and the type of clothes
Try in this order
0 of 5 completedConfirm it is a sensor cycle
ReversibleThe Sensing indicator lights during sensor cycles and not during timed cycles or options such as Wrinkle Prevent. On timed cycles the time is fixed.
Change the dryness level
ReversibleMaytag's help says increasing or decreasing the dryness level changes the amount of drying time in a cycle. Sanitize has no dryness setting.
Level the dryer
ReversibleIf a sensor cycle ends early, the load may not be contacting the sensor strips. Level the dryer front to back and side to side.
Use Timed Dry for tiny loads
ReversibleFor very small loads use a timed cycle, which does not depend on the sensor.
Watch the status lights
ReversibleWet means the load is still wet or the cycle just started. Damp is a good point to remove a garment to air dry or iron. Cool Down means heated drying is finished.
Model-specific
What is true of this model and not of its siblings
- Check Vent indicator behavior
- Maytag's quick start says the Check Vent indicator is available for sensor cycles only and reports airflow through the dryer and the vent system. During the sensing phase at the start of a cycle it comes on if a blocked vent or low airflow is detected and then stays on for the whole cycle. It clears at cycle end, on touching Power or on opening the door, and does not light if another error is present.

Stop boundary
When this stops being a self-service repair
- !If sensor cycles end early with a level dryer and a clean vent, contact Maytag service
- !If the Check Vent light returns after cleaning, have the vent inspected

Exact questions
Common questions
What does the Sensing light mean?+
The moisture sensor on the dryer is operating during a sensor cycle.
Why did the cycle end early?+
The load may not be contacting the sensor strips. Level the dryer or use Timed Dry for tiny loads.
What do Wet, Damp and Cool Down mean?+
Wet is still wet or just started, Damp still has moisture, and Cool Down means it has finished heating and is tumbling to cool.
What is the Check Vent light?+
It comes on during the sensing phase if a blocked vent or low airflow is detected and stays on for the cycle.
Does the dryer stop when Check Vent is on?+
No. It continues but poor airflow can lengthen drying.
Can I use Sensing on Sanitize?+
Sanitize has no Temp. or Dryness choice.
What if the dryer is cold?+
Below 45 degrees F it may not shut off at the end of automatic sensor cycles.
