The dryer won't stop running after a heating

What happens when power comes back on

You will need to replace the timer. Here is the part to order.

test the push button for open and faulty .However see this causes too.

Clogged Vent
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.


Heating Element

Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.


Cycling thermostat

Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork . This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

Dryer Won't Stop Running

• Ultimate Car II Dryers are fitted with a mechanical timer that sends an impulse to the control circuit board to stop running once the set amount of drying time has elapsed. This is because, should an electronic timer fail, this would necessitate the replacement of the entire circuit board. Confirm that the mechanical timer is indeed broken by opening the dryer's door. If the dryer stops, the circuit board is working fine and is not the problem. Simply slide off the protective faceplate of the dryer, unscrew the control board beneath, and flip it over. Connected to the back of the timer's knob should be a small round device with two wires running to the circuit board within the body of the dryer. Unscrew this device from the back of the knob and disconnect the wires. A replacement timer costs a few dollars and should screw into place without trouble. Reconnect the wires and put the dryer back together. It should work fine now.
  
• If you need a new timer the best place ti get it is from Rough River Appliance Repair
• Phone number is (270) 230-1818 his name is Charlie and he is the best!
  

If its on automatic cycle the timer won't advance if theres no heat. It will advance on timed cycle, though.

Since you say that the dryer runs but have no heat, plus the timer won't shut off the odds are the timer is bad. The timer would tell the burner when to be on and when to shut down.

Timer

HI, The timer control module is the culprit. This device controls the heating functions of your unit. You have indicated that the timer will not stop the unit, and it continues to run after the cycles intended stopping point. This will confirm that the timer is damaged, and it should be replaced asap, if possible.

NOTE:-( Just to be safe, check the thermal fuse as well. This is a emergency cut-off fuse that will blow if the element overheats your unit. it is located on the blower housing, or vent duct inside the unit. Test the fuse for continuity. If it is ok, replace the timer).

HI. This is a defective, or damaged timer control module. It must be replace asap. If this continues, it will damage the element. Replace the timer, if possible. Once replaced, the issue will be solved.
