Vchipoker January 14, 2017 for Model Number MDG9700AWW Gas dryer was not igniting or gas valve not opening. Repair man a year ago replace thermostat and it still ohms out good. Also I replaced valve coils since one was replaced by same repair man. Since the problem still persists I also replaced igniter on a whim of luck. Currently it will work a couple times a day but not every time. I have tried fervently to find the problem but have only come to see that it may possibly be the gas valve assembly entirely. I am an electrician and need help on this one. Maybe thermistor? It reads resistance on that still but I am out of ideas. the ducts are new and its now operating sometimes. Could the Heater Relay be acting up? No parts are grounded and only codes reading out were "255" not sure what that is and "2" for thermistor but it could have been from when I was running live tests. Any ideas would be very helpful I was like to keep this dryer instead of buying one.
1 Answer Vchipoker, You will want to check the flame sensor to make sure that it has continuity. If this has continuity then it is ok but you will also want to check for a shorted booster coil, open wiring a possible bad motor switch. if all these things check ok then the issue will be a control board that is faulty.

Jonathan September 05, 2016 for Model Number DV339AER My dryer will turn on and run, but does not heat up. I've tested the thermal fuse for continuity and it seems fine, but the thermistor does not. Would a blown thermistor cause the dryer to run but not heat up? When I attach the multimeter the display stays unchanged. I'm hoping I can just swap out this part and be good to go!
1 Answer Jonathan, Yes the dryer thermistor being faulty can certainly allow the unit to run but not heat and would be recommended to replace this thermistor. Read More...
Roy January 08, 2016 for Model Number MDE9700AYM I have replaced my high heat thermal fuse. My dryer ran for approx 10 minutes and it stopped producing heat. I checked and the thermal fuse has no ohms value again, meaning its blown. I also checked my transmistor. It to has no ohms value. Do I need to replace both and is it the cause for the thermal fuse to keep blowing?
1 Answer Roy, You will want to replace both parts but the most likely cause for the unit to not work would be a vent that is clogged up. Check the venting from the blower wheel to the outside of the home. Read More...
Pete October 15, 2015 for Model Number samsung gas dryer My Samsung gas dryer heater was shutting off after running for few seconds. Checked thermistor and found no continuity, checked thermostat and thermal fuse both had continuity. ordered new thermistor and also thermostat just to replace since access was there. Installed both parts dryer has same issue. Removed and tested new thermistor still no continuity. Checked thermistor with two different volt meters. Had same result. Is it normal for thermistor to have no resistance? Or is the new thermistor bad? Thanks for any help.
1 Answer Hello Pete. Thermistors do not have continuity. The have an ohms value. Running a few seconds and stopping is either a bad motor or bad control board in the unit usually. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
J October 07, 2015 for Model Number MDE9700AYW My dryer will not heat up, so I opened it up. My question is if I put a multi meter on the contacts on the Thermistor should it register on my meter. I checked all of the sensors on the heater and all of them registered. The thermistor did not. I do not want to order the new part if its not the right part. Thank you for you help in this matter.
1 Answer Hello J. You can test the thermistor. It should read 10,000 ohms at 77°. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Chris June 30, 2015 for Model Number 110.73932.102 Dryer runs but won't heat. No igniter, no flames, no gas valve cycling. Checked continuity on most parts and found I had a bad thermistor. Does this sound as though that would cause the symptoms I am having? Thanks, Chris
1 Answer Hello Chris. Thermistors do not have continuity. They read ohms resistance. You need to check for power to the igniter and if there is power there, you will need to replace the igniter on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
Tom J June 13, 2015 for Model Number dv210agw/xaa When the dryer completes its drying cycle it looks like two c circle the dryer code and the dryer will start an run and continue to cycle on and off.
1 Answer Tom, This feature is called the wrinkle prevent. Wrinkle Prevent provides approximately 90 minutes of intermittent tumbling in unheated air at the end of the cycle to reduce wrinkling. Press the Wrinkle Prevent button to activate this feature. The indicator light above the pad will illuminate when Wrinkle Prevent is selected. The load is dry, and can be removed at any time during the Wrinkle Prevent cycle. Read More...
Randy May 29, 2015 for Model Number 110.68062801 Can a bad thermistor (8577274) cause the dryer to over heat and blow the thermal fuse?
1 Answer Randy, Yes a bad thermistor or a bad thermostat could cause the unit to overheat and blow the thermal fuse but you will also want to check the venting as this is the most common cause for the thermal fuse blowing and unit being too hot. Read More...
Bud April 11, 2015 for Model Number Amana ned7200tw My friends dryer will start cycle after running 15min it will completely turn off after 15 min it will tun on with time still remaining on control will restart and stop again. Vent is clear, thermostat tested nc no codes on dial can it be control board?
1 Answer Bud, You will want to check for bad drum rollers which could cause drag on the motor and cause it to overheat. Also check the blower wheel and venting all the way to the outside of the home which if clogged could cause overheating issue of the motor. Read More...
Steve November 01, 2014 for Model Number NGD7200TW Controls work. Dryer does not ignite nor spin when turned on. Makes a "click" does when button is pushed to turn on, but nothing happens.
1 Answer Steve, You will want to check the door switch for continuity in the closed position. If there is no continuity then the switch is faulty and would need to be replaced. Also test the thermal fuse and make sure that it has continuity. In most cases one of these 2 components would be faulty and be in need of replacement. Worst case would be both being good and the motor being faulty. Read More...
