Heating element stays on

If the door is opened during the drying cycle the heating element stays on causing the dryer to overheat and preventing it from restarting. Once the dryer cools down it restarts. If I turn the dryer to off before I open the door no problems

    Thank you, Just to make sure the Dryer is overheating because the Heating Element stays on when the door is open. So if I disconect the vent hose clean the vent and I still have the issue. Replace the Cycling Thermostat and that should fix the issue with the element staying on.

  • ldeliman Apr 06, 2009

    I did the above recomended changes and the problem still exists. If the door is opened before the cycle ends the heating element stays glowing red and the dryer will not restart till it cools down. Do you have another suggestion?

Stat or a clogged vent system. Clean any lint from the internal and external ductwork, and/or replace the cycling thermostat (read about cycling thermostats in "Drying is too slow," above).
Drying is too slow It normally takes about 45 minutes for a dryer to dry a full load. If your dryer is taking more than an hour, check these.

Vent
Heating element
Internal ductwork
Cycling thermostat
Vent Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance. 

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 it. 

Internal ductwork Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum, contact a qualified appliance repair technician.

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 with two screws.

My GE Dryer is not drying my clothes completely on the first cycle but when I feel inside the dryer it feels hot? Do you have an idea of what could be the issue Model# DJXR433EG1WW


If your dryer still heats, but your clothes take longer than usual to dry, you may want to check the dryer interior cabinet and/or the entire run of the exhaust ducting from where it exits your dryer to the point where it leaves your home to ensure you have no kinks, clogs, or excessive bends. The following link explains many of the common problems that can cause poor drying efficiency and longer dry times:

http://www.fixya.com/support/r3578821-dryer_takes_too_long_to_dry

Before assuming you have a problem with the appliance, check your installation to ensure you are providing the dryer with proper exhaust and air flow. This is the NUMBER ONE cause of poor drying efficiency. A dryer that is clogged, or has restricted air flow, will not dry efficiently and will cause the heating circuits to OVERHEAT. This will eventually will lead to component failures and is the source of many fire hazards.
Exhaust ducting that runs to the attic is usually the worst configuration, because the air has to be forced up. The blower fan will meet more resistance and any lint that does not exhaust completely, ends up stuck in the vent. Water appearing in the drum is another sign that you have a clog somewhere causing condensation to develop. FYI: There are no adjustments that can be made to any of the internal thermostats or heating element to make it run at a higher temperature. All these components have a fixed setting. If the dryer still produces heat, this is generally a sign that the heating element IS working. If the dryer is clogged, however, the internal protection devices, such as the Hi-Limit Thermostat and Internal Bias Thermostat will shut the heating element off prematurely to prevent the dryer from overheating, and to prevent damage to the heating element. Eventually, the Thermal Cut-Out (TCO) or Thermal Fuse will trip and the dryer will not run.or produce heat. If you have any questions, please post back and let me know. I hope you find this information helpful.

The clothes take several cycles to dry. I removed thae back and looked at the works while the dryer was running and the heating element cycles on and off. I assume the temperature isn't stayingon long...


ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor one at a time by removing the two wires and taping them together with electrical tape and running the dryer to check to see if the element is red or not,
or with an ohm meter check the two terminals of the thermostat/thermister
after you have removed the wires, the thermostat/thermistor should have/show continuity across the terminals.
If the coil heats up, or the thermostat/thermistor shows an open circut
then replace the thermostat/thermistor as it is defective.
(Thermal fuse.If it overheats the dryer will not operate. It's located on the blower housing. It cannot be reset. A vent clogged with lint can cause it to overheat. You can test it with an Ohm meter or continuity checker, if no continuity, replace it)
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST.
This could cause a FIRE, as you have removed the safety of overheat from the machine.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Dryer runs but the heater element gets hot then shuts off. After a few minutes it will heat up again. Is the problem more likely: the hi-limit thermostat or the multi-temp thermostat or the thermal cut-off...


The heating element is SUPPOSED to cycle on and off. The element has a regulating thermostats to ensure it does not get too hot. If the element were to stay on continuously, the dryer would overheat to the point of the element eventually failing, or create a fire hazard. It will cycle on and off dependent upon the internal temperature the moisture level in your clothing (if you are using the Auto-Dry feature).

If your dryer IS still heating, but you are experiencing longer dry times, you may want to check the dryer interior cabinet and/or the entire exhaust duct run to ensure you don't have any clogs or choke points. The following link explains many of the problems that can cause poor drying efficiency:

http://www.fixya.com/support/r3578821-dryer_takes_too_long_to_dry

Before assuming you have a problem with the appliance, check your installation to ensure you are providing the dryer with proper exhaust and air flow. A dryer in a clogged state or having improper air flow will not dry efficiently and will cause the heating circuits to actually overheat. Eventually, this can lead to component failures and is the source of fire hazards.

If you have any questions, please post back an let me know. I hope you find this information helpful.

My heating element stays on for about 15 sec at a time-is this normal?


Is is normal for the heating element to cycle on and off. The element is usually protected by an operating (or hi-limit) thermostat that helps regulate the internal operating temperature. The element is not supposed to stay on continuously or you could end up with a scorched clothing, or a fire hazard. As your clothes get dryer, the heating element should cycle less. As long as you are not having any problems with dryer performance, you shouldn't have anything to worry about.

However, if your dryer is heating, but you are experiencing longer dry times or poor drying efficiency, the following link can give you some things to check before you assume there is a malfunction with your dryer:

http://www.fixya.com/support/r3578821-dryer_takes_too_long_to_dry

The number one cause of dryer heat related problems is poor exhaust ventilation. If not vented properly, a dryer will not dry efficiently, will actually take longer than required to dry, and will cause the heating circuits to overheat to the point of failure. The dryer will actually seem hotter than usual in many cases as the heating circuits begin to overheat. This is also the source of many fire hazards if not resolved. Read through the link provided and review some of the potential causes.

If you have any questions, please post back with your MODEL NUMBER and let me know. I hope you find this information is helpful.

NOTE: If you thoroughly check everything and still have problems let me know. The problem could be related to a thermostat failure.

Roper REX5634KQ0 runs for two minutes in any cycle and then stops


This problem sounds like a bad motor bearing causing the motor to overheat, when the motor overheats there is a thermal protector that opens and the motor will not run until it cools down.

Heating element stays on after the drying cycle stops and the timer will also continue on with the door shut or open once you start a drying cycle. I replaced the timer and the start push button.


I would suggest that you check the door switch, as the m/c should not work with the door open,whilst the door switch is made everything will continue to work.
Plz rate my solution.
Thanks.

Based on the information that you provided, if you open the door in mid-cycle and the motor shuts off, but the element stays on, this will stop the air flow through the dryer and the element. The element temperature will rise drastically because it is not being cooled. Subsequently, to prevent a fire, the thermal fuse will open, shutting the element, and in some cases the motor, down.
A heating element gets its power from the timer, through the cycling thermostat(s),and to 1 side of the element.
When the motor starts, power is passed through the centrifugal switch in the motor, through the hi-limit thermostat and the thermal fuse to the other side of the element.
There is no ground wiring involved in the heat side of the dryer.
1. An element can stay on because it has broken and fell against the metal tube where it picks up a ground. Solution is to replace the element.
2. The centrifugal switch mounted on or in the motor can fail to open when the motor stops and allow current to flow through it
until the points in the timer open up, breaking the circuit.
