1. When you set the timer knob for the dry cycle it gets stuck and dryer keeps running. 2 The dryer turns on and runs but does not always ignite to provide heat. Heat source LP Gas.

Oh I can't think of the name of it right now but the whole knob assembly inside needs to be replaced. It's like a timer its integrated into the knob.

HI,

If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.

Normally, this is what happens during an automatic cycle:

• The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.



• When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)



• The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.

This cycle continues until the clothes are dry. But…if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

90% sure it's the timer

Look like you need a timer control
model number should start with a 110. number timer for your dryer is about $70

there is a cycling thermostat in line with the high limit thermostat and timer circuit,on timed dry its disabled and the timer will run no matter what,on any sensor dry setting it uses the heat of the element to heat this cycling thermostat to move the timer as the clothes get drier as the heating element heats the timer doesn't move,when the heater cycles off from the high limit thermostat then timer moves again,you need to find out if its a bad heating element,thermal fuse or possibly even a circuit breaker in the homes electrical panel tripped out on one of the 2 phases that gives you the 240 volts required to operate the dryer element,the breaker may not show its tripped,so shut it off and back on and try this first

Verify that the wrinkle prevent switch is good. If so, the timer is likely the problem. Sometimes the switch contacts inside the timer can be cleaned to restore operation, bit it is a tricky item to disassemble and reassemble.

check the ignitor element those go bad after long usage... if you see that when you turn the machine on and the ignitor turn red but the flame not start then you need to replace it.
let me know if it help you , if not let me know as well we will keep working on it...

check the vent or could be the coils

hi thanks for the question in the ge dryer theres 2 elements so if one is not working you only get half heat i would check the heater thanks the appliance doc
