With the fuse blowing this quickly you most likely either have a shorted heating element or a bad control board that is constantly sending power to the heating element. A quick test you can do is run the dryer on an air fluff (no heat) cycle and see if the dryer heats up. If it does then the heating element is shorted or the main control board is bad. The video below shows how to test the element. If you find the element is bad and shorted make sure to check your exhaust venting for restrictions.

The lint filter should be cleaned before every time you run the dryer. There are no pressure sensors, but the restriction in the airflow can cause the temperature to act differently than it normally would since the heat can't escape out the exhaust venting like it normally does.

c'mon Doc, cut me a break. this dryer heats sometimes and does not heat other times. there must be something that could be the cause. could one of the safety switches have an intermittent connection problem? Am I dealing with ET's?? you guys designed this abortion.
i have a samsung dryer that gave me a code eh. i replaced the entire heating unit ie: thermostat, heating element the entire silver unit at bottom. I ran a voltage test 120 on top 120 on bottom still no heat. original part I removed had no breaks. what could the problem be. Any help would be appreciated.
My dryer has not had a heating problem for about a month now. the only consistent thing is that if we forget to clean the lint filter every time (very little lint) it stops heating for about a day and then works normally again. There must be some sort of sensor on the air flow that turns off the heat and does not immediately reset. Otherwise we are dealing with an intermittent defect which is hard to believe.
I have an issue with my Samsung front loader. My heating element went last year, replaced it. Now during Xmas it quick heating again, thought it was my heating element again. Replaced the thermal fuse because that was bad, replaced it. Now a week later and it stopped working again any ideas. I won't be able to take it apart until tomorrow night.
I NEED HELP
My dryer samsung DV42H5400GW/A3 (GAS) is not heating, checked the vents they are clean, changed Therm, thermistor and thermal fuse... still not heating.... what else can I do?? please HELP. BTW I'm not very savvy about this things, I just follow the videos to replace this parts.
thank you guys.
Apologies if this question (or some variation of it) has already been asked or answered. My Samsung (model DV42H5200EW/A3) dryer stop producing heat. I bought a new heating element, and following YouTube instructions, replaced it. Dryer still doesn't produce heat. I set it on normal mode with a damp towel in there, and it runs but doesn't produce heat. It starts at a 48 minute cycle, then runs down to 47 minutes (after a minute, obviously), then jumps to 1 minute before shutting off. I'm assuming there is an issues with the thermometer/thermostat?
I'm pretty sure I replaced the heating element correctly. There is a chance I put the wires on the heating element back on incorrectly (my smart phone died right when I got to the point where I needed to remove the contacts, so I didn't take a picture, but I did make a mental note; of course, there could always be human error). IF I put the contacts back on the heating element incorrectly, would anything have happened (shorted the system, etc.)?
Thanks in advance.
I am also having a similar issue with my DV219 Samsung Dryer. My heating element went out and I replaced it. Unfortunately the new element had a short in it that caused the element to fail. I replaced the element again and this time I got no heat. I replaced the thermostat because I was getting no resistance and the dryer ran with heat for about one cycle before the heat went out and the machine displayed "1" on the display.
What other part could be going bad?
I had the same thing. i replaced the control board and even talked to the local tech for 30 minutes with no luck. I finally found the one thing which can stop the heater relay from activating when everything else checked out ok. Every time I put a volt meter on Pin 5 & 6 of the Centrifugal Switch on the motor, the heater would come on. It finally dawned on me the meter was acting like a jumper and completing the circuit. Turns out the relay in the Centrifugal was bad and not completely the circuit which is somehow needed to trip the heater relay. I put a test jumper on the relay and ran a cycle and it worked fine. I am now just waiting for a new motor to come in. Hope this helps!
Similar issues, and am at a loss now. I have a Samsung dv42h5200ep/a3 dryer that is not heating. I have verified the vent is clear, verified the correct voltage coming in to the unit, replaced the heating element, replaced the thermostat, replaced the thermal fuse on the heating element housing, replaced the thermistor. I have checked the relay on the main board, and it seems to be working correctly. I have actually checked the voltage on the heating element while the dryer is running, and have 120v on both legs, but still no heat. The dryer will not heat on any setting. One weird thing is that if I set it to a timed cycle of say 20 minutes, it will only run a few minutes and then goes into the cool down stage and ends the cycle. Please help with any suggestions...
I am having heating troubles as well. I have a DV45H7000EW. I have already changed the heating element, thermistor and the other sensor. Breakers are good. What else could it be? Main control board possibly?
First check the power with a meter.
Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
Check the voltage at the wall receptacle
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.
Be careful as 240 volts is lethal !!!
I have a Samsung dv350aew and have replaced heating element 3 times in 4 months. Replaced it yesterday and dried 3 loads and now it won't heat again. Lint filters and vents are clean and getting good flow. Amy suggestions? I can't keep buying heating elements! Every time I replace the heating element it fixes the problem for a while. What would cause the element to keep going out?
Check that the heater assembly is solid.
Check that the dryer is not vibrating too much.
A shaking dryer can blow a hot element.
The high limit and thermal cut off may be blown.
Often an overly hot element can blow the element but the above two parts are meant to prevent this and fires.
The way it works is that if the heat relay is not regulating the temperature for some reason then the high limit starts controlling the heater.
The contacts in the hi-limit are not the greatest so eventually they fail. Often welded shut the thermal cut off (fuse) then blows.
This is assuming that the heater is overheating and blowing the heater which is expensive and also a fire hazard!!!!
Try different temperature settings to see if the unit is actually regulating the temperature.
Also I would check the voltages at the dryer's terminal strip.
Below is a link to a tech sheet for this unit.

samsung dryer dv56h9100eg/a2 thermal cut off switch KEEPS FAILING. repair guys have replaced it twice already. It runs good on first load, then fails after that. It is getting to be expensive. all repair guys just say, it is all about air flow. It is still not fixed, after 4 visits.
Hello,
We are having the same problem too. The dryer isn't heating, there is no air flow problem, the incoming electricity is at the correct voltage, and there are no Error codes. We have replaced the whole heating element assembly complete with the thermostat, cut off fuses, and the thermoster. We noticed that once that it was started and said the time was 40 min, and got something to drink and came back after 2 min and the time said 20 min. Could this be the control board? I thought it was a timer problem, but I can't find that in the parts diagram. Considering buying a dryer, but not a Samsung as it seems that they are built to only last 4 years. This is our first time trying to fix a dryer, so any help would be appreciated. Perhaps I should be asking what a good dryer brand is too! hahaha.
Model number is DV42H5000EW/A3 (i don't know the next 4 numbers as its not in the door)
Electric not gas model.
