Тәжірибелік нұсқаулар және стиль

If you are a service technician or a DYI’er that has a dryer that seems to keep blowing the same component then you should watch this video. It explains how each component functions together with others to make your dryer work properly.
We show you how to test your machine to determine if you should replace parts or just clean your vents. Be sure to watch to the end to determine if your machine fits this repair or if more expensive measures might be needed.

    The cycling thermostat is what the viewer is mistakenly referring to as the cycling switch. You can see one about 1:13 into the video. On his Samsung machine he is probably referring to the thermistor. It is the thermostat located on the blower that has four spade connections on it if you have a Whirlpool style machine. On the Samsung it is a two spade plug devise called a thermistor. It should turn the element off when it reaches around 150 degrees Fahrenheit.

  • @HarperandKnowles

    It's normal to get an initial burning smell after opening up a dryer and repairing it. You disturb dust particles and lint while your in there and when you restart the machine it will pick up this small amount of debris and pull it through the element where it burns up in the stream of hot air. The smell usually subsides after a few minutes. A continued burning smell may be cause for concern, but if everything is working correctly it should go back to normal after just a few minutes oof operation. I hope this helps. Thanks for watching!

    It’s always a good idea to replace all of those components when you replace one. Check that your element isn’t grounded to the frame. Now, some Samsung models regulate temperature from circuitry on the control board. If changing the thermistor doesn’t fix it and the element isn’t grounding it’s the control board.

    Turn the timer to the timed dry setting, try the 40 minute mark. Turn it on and let it run for about five minutes. Be sure the room lights are off and open the door. Look inside and see if you can see the glow of the element behind the hot air inlet. If you see a steady glow then your element is grounding out on the frame and should be replaced.

  • @HarperandKnowles

    No start issues can usually be run down to, 1) a faulty door switch 2) a blown thermal fuse on the blower side 3) a broken belt 4) a faulty belt tension switch 5) an over heating motor 6) a bad start button or 7) a bad control board. The thermal cutoff fuse will blow if cycling thermostat doesn’t work, or element is shorted, or obstructed airflow. When you eventually find it you’ll wonder why you couldn’t find such an obvious problem to begin with. I do it all the time! Thanks for watching.

My heating elemenet has continuity and is not grounded. I am planning next to replace the cycling thermostat in addition to the blown fuse. I suppose there is no need to replace the thermal fuse (196F) on the blower assembly if it has continuity? Also, considering that I have replaced the high limit thermostat and the element is not grounded, shouldn't the thermostat have stopped the thermal fuse from blowing, given that the thermostat opens at 250F whereas the fuse opens at 309F?

    If you have good airflow and your element isn’t grounding to the frame then your cycling thermostat is probably malfunctioning. Here’s how to test that. With no clothes in the drum and the dryer timer setting on a high heat cycle, remover the vent hose and place a thermometer that reads at least 200 degrees Fahrenheit at the exhaust vent opening. Turn the machine on and watch the temperature climb. The cycling thermostat should click off at around 155 degrees give or take 5 or 10 degrees. You can usually hear the click when this happens. Now your temperature will continue to rise because there is still hot air coming through but in a few seconds it will start to drop until the cycling thermostat cools enough to close again. Then the temperature will rise again. So, if your thermostat clicks off but your temperature continues to rise 175-185 then turn the machine off before it blows another high limit thermal fuse. This tells you that your heating element is expanding enough to touch the shroud and ground out. This is real hard to detect because it pulls away from the frame when it cools and will test good when you do a continuity check.

I have replaced these five times in the past three weeks. The heater won’t shut off it keeps getting hotter and hotter until the high limit thermostat cuts off. I have checked all the thermostats, the thermistor and heating element for ohms of resistance everything passes. I used my blow dryer to heat up on the thermistor. After all the trouble shooting it keeps blowing. Could my main control board not be functioning correctly? If so how can I check this? I can’t find any information for my issue.

    If all of your other components check out it is going to be the board. There is nothing else in the circuit. And if your machine has a thermistor it doesn’t have a cycling thermostat. There may be a way to check the temperature control on the board but I don’t know how. I believe those components are sealed in a jelly that would prevent you from accessing the soldered points where you could test continuity and resistance. Yours may be different. I’m willing to bet if you change that board your problem will be solved.

    Use a thermometer at the exhaust with nothing in the tub. Be sure the cycling thermostat is operating correctly. It should click off around 150 degrees and the temp should start dropping about 165. These temperatures can be a bit higher or lower but if the temperature fails to drop after reaching 180 then either the cycling thermostat is not working properly or the element is grounding. I’ve seen new components that fail. Also check that the temperature of the thermal cutoff fuse is the correct rating for your machine. Some are 309 degrees up to 352 degrees. These are Whirlpool components?

I just replaced the heating element before I wrote the text. I did have a wire pop off the thermal cutoff and ground out and I'm thinking it might have blown the new switch, but it checks out good. Either way, I just bought a whole new set of switches and fuses, going to replace them all again. If that don't work, I'm going to jump the fuse and use it any way.

    That is interesting but I'm skeptical. It's usually a grounded element that keeps the timer motor from running. Also, if you have your timer set to the cycles on the left hemisphere side of the indicator on some models (auto cycles) the timer only advances when the cycling thermostat is off. There are a few ways the timer motor won't advance and all of them are confusing as hell. The likelihood of 5 timers having the same problem is really unbelievable.

    If two different dryers are causing the same problem in the home breaker box then there is probably a problem with the home wiring. If it is an immediate blow then there is a direct short, perhaps a bad receptacle. If it blows after running a bit then there is a problem with an overloaded circuit. Something is causing the fuse to blow. Try checking your dryer at another receptacle, like in another home. Two dryers with the same problem would be a rare coincidence. I can't help you with your landlord problem, but it sure sounds like it's probably something he should have checked.
