Rodney Y. October 25, 2012 for Model Number DV448AEP.XAA Thermistor reads 00.7 at room temp. Would this cause overheating?
1 Answer Hi. Yes the thermister part # WP35001191 can cause over heating because of the improper tolerances given. At room temperature of 77° it should read 10K ohms. Thank You. Read More...
Cheri August 31, 2012 for Model Number MDE6700azw Hey My dryer will not heat. I have replaced the circuit board. It still will not heat. I am trying to test the thermistor and it reads OL on my multi meter. All other thermistats are good. Any ideas on what else it might be? Thanks
1 Answer Hello Cheri. If the thermistor does not show resistance, you will need to replace the thermistor WP35001191. Read More...
Bill August 13, 2012 for Model Number DV306LEW/XAA The thermister in my machine reads 26.4K ohms @ 78 degrees F. Would this account for the dryer running hot and the subsequent burnout of Thermostate 1 (P/N AP4045367)?
1 Answer Hello Bill. It could be the issue. The thermistor WP35001191 is bad and will need to be replaced on the unit based on the test you performed. Read More...
Bryan July 15, 2012 for Model Number samsung dv337aer/xaa What is an acceptable ohm range for the thermistor? I am getting almost 12,000 ohms at room temp. Also what kind of voltage should I be getting at the thermistor while the dryer is running?
1 Answer Hello Bryan. According to the manufacture, the thermistor WP35001191 should read around 10k at 77°. There is no voltage at the thermisotr. It is used to send an ohms reading to the contorl board, not voltage. Read More...
Mike April 14, 2012 for Model Number MDG6700A The gas dryer ignites with front off and no venting (fooled the door switch). It stays on for 30 seconds and turns off. Checked Hi limit, and all sensors and coils. They are all within specifications. Could this be a weak hi-limit thermostat?
1 Answer Hello Mike, This is definitely a coil or safety valve issue. I would probably replace the coils 279834 first in case one is breaking down under load. The coils are cheaper that the safety valve. If this doesn't correct it, it will be the safety valve WP35001190 that corrects the issue. Read More...
Steve February 12, 2012 for Model Number MDE6700AYW Would partial failure of this item allow the dryer coil to overheat and burnout the coil thermal fuse ? I have new duct dryer vent ductwork and no blockage in the flexable alum duct. I have replace the thermal fuse and regained use of my dryer but now it is blow again. I have read the resistance and it is close but not at the required so I am wondering if there may be further degridation of the control when it heats up.
1 Answer Hi Steve. It sounds like the thermistor which will ohm out to 10,000 ohms cold +/- 10 %. It is part # WP35001191. What can be sticking on to allow the overheat is a concern. Is the vent kinked when pushed back in ? Look at it in position. Is there a bad blower wheel that is scraping and needs changed part # DC67-00180B. The air flow movement is a very tightly needed calibration. The heater relays have been known to stick shut and allow over heat part # WP35001153. Use the tech. sheet supplied inside the unit to see if there are any diagnostic codes showing. It has been my estimation the control board relay is more the issue. If you did had a restricted vent right before the vent cleaning and the motor is clogged , then the heater expansion has already taken place for so long that it only now takes a little heat to relax it enough to over heat and short out. Element part # WP35001247. Thank You. Read More...
Robert July 21, 2011 for Model Number mde9700ayw On the control board and the PCB assy. where should I check for power and what voltage should I see. Is there a schematic of these 2 components? One other thing I noticed the PCB board has a little speaker/chim that when dryer is plugged in is making a very quite buzzing noise if that helps in any way. Thanks, Robert
1 Answer Hello Robert. You will test across the white and black wires on the PCB assembly. You should read 120 volts AC. Hope this helps. Read More...
Robert July 20, 2011 for Model Number mde9700ayw Would this sensor (Thermistor Part Number: AP4045224) with 8740 ohms at 77 deg cause dry not to come on at all? All I have is the light inside dryer that comes on when door is open and goes off when door is closed. I can not get anything else the panel will not light up at all. I have 220 volts at the junction at the back of the dryer and those conections are tight and show no signs of heat or corrosion. Thanks, Robert
1 Answer Hello Robert. No, the thermistor WP35001191 will not cause the dryer not to run. You will need to test and see if there is power going to the front control board. If not, you may have a bad PCB assembly WP35001153. If there is power there and the board does not work, you will need to replace the control board 35001227 You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter.
