Automatic timer does not advance but timed heat does advance ge model dbxr453ea1ww

do you have heat?does it stay hot while in coll down?if so your heating element is grounded,open the door,look up and remove the two screws holding the top panel in place,pick top panel up just a little and move it to the left that should remove the top panel, put it on cool down or no heat and run it,if the heat stays on this is your problem the element is sagging and touching the metal cover around the element,the way the timer works is on timed dry it counts down like a clock until it turns off when on more or less or auto same thing the dryer starts,the heat comes on and when it hits temp. the heat shuts off when the heat is off the timer will advance to off when the heat starts again the timer stops,if the element isn't grounded then you still could have a bad element there are two elements in your dryer if one is broke the timer won't advance or some have only one element so if the timer doesn't advance you probably have no heat or a bad cycling thermostat or a bad sensor up front where the lint filter is.you'll have to check them with a meter.first thing to check is the heater located behind the drum.

Unplug the unit from the power, or shut off the breaker. Open the unit and check that all wires are firmly connected, no loose ends or broken wires. If all connects seem tight and the wires are in good condition You may need to replace the timer switch. The link below is for the users/owners manual for your machine:

that model number doesn't come up,you sure that isn't the serial number?also does the dryer have heat,when you run it on time dry the timer just counts down like a clock,when on auto or more or less the heat comes on until the dryer heats to temp. the heat shuts off and the timer will advance,when the heat comes back on the timer stops moving,it will do this until the clothes are dry,if you do have heat you could have a bad sensor or a bad cycling thermostat but you'll have to check it with a meter.send the model number and i can help you better.

follow this steps and fix it. God bless you

Timer
The timer could be the problem. To check this, turn the timer to a timed cycle say 30 minutes or so then time it. If in 30 minutes the timer hasn't moved and the dryer is still on, the timer is bad and need replaced. If in 30 minutes the dryer is off, the heating element is your problem

Heating Element
This is the most likely cause for some dryers timer not advancing. Some dryers have two heating elements and if one goes out the timer will not advance if you use it on an automatic cycle but you will still feel heat inside the tub. replace the heating elements

When any automatic cycle is selected heat is required for the timer to advance. Timed dry should advance with or without heat. You should check your heating element for continuity as well as all thermostats. Location of these components depends on the brand name and model.

There are two coils in the heating element, and if one burns out, the timer will not advance in automatic dry. The timer should still advance when using manual (or timed) dry.

you need a timer you can probably take the old timer in to your local appliance part store and get a new one

depending on the model; if the timer is in the automatic cycle it will not advance if there is no heat, it must heat in order to satisfy a thermostat to tell the timer to advance this is what makes it automatic. If the timer gets to the end of the timed cycle and will not advance to off, sounds like a bad resistor connected to the timer, I would first check the heat circuit to find out why its not heating. Dont mean to complicate, but everything in the dryer has something to do with heating, element,thermostats, temp switch, timer and even the motor. Check for burnt wires at the terminal block for the cord. hope this helps.....

Check your heating element. If one coil of the heating element is burnt out the dryer will heat on the remaining coil, but the timer will not advance in automatic dry.
