sounds like a bad timer. if it sticks every time replace they are expensive

if your clothes are damp because you say it does dry some what then it sounds like it could be the gas coils,the coils will work for awhile but then they fail and the timer will not move if there is no heat on the more or less

switch is going out

You can make adjustments to your Automatic Cycles by adjusting the Factory Dryness Level:
Changing the Automatic Cycle settings to increase or decrease drying time:
If all your loads on all Automatic Cycles are consistently less dry or more dry than you would like, you may change the default settings to increase or decrease the default dryness
level.

Your automatic drying settings can be adjusted to adapt to different installations, environmental conditions, or personal preference. This change is retained and will affect all of your
Automatic Cycles, not just the current cycle/load. There are 5 drying settings, which are displayed using the time display:
0 Much wetter clothes, 30% less drying time.
1 Slightly wetter clothes, 15% less drying time.
2 Factory preset dryness level.
3 Slightly drier clothes, 15% more drying time.
4 Much drier clothes, 30% more drying time.
TO CHANGE THE DRYING SETTINGS: NOTE: The settings cannot be changed while the dryer is running or paused. The dryer must be in standby mode (power is off) to adjust the default settings.

1. Before starting a cycle, touch and hold DRYNESS for 6 seconds.
2. Touch DRYNESS to select the dryness level shown in the time display: 0, 1, 2, 3, or 4.
3. Touch START/PAUSE to save the new dryness level setting.

When you moved the sensor wire on the moisture sensor may have fallen off.
Remove the front panel and locate the wire and the connection. It will be on the right side near the lint filter vent. If it is still connected your timer has gone bad.

I have a Maytag Atlantis Gas Dryer that will turn on, rotate, but will not get hot and dry the clothes. A load of clothes in the afternoon, didn’t dry, tried again but didn’t dry – went to bed after putting on auto dry - next morning the dryer was still rotating and didn’t turn off. No hot air – only cold air.
