I watched the online video on Appliance Parts Pro site. I am mechanically inclined and like saving money so I decided to fix it myself. Video is excellent and easy to understand if you follow every step and mark wires and take pictures on phone before you take off wires and parts to use as reference later. My Samsung front loader was purchased in 2009. I had a good idea that the heating element was the problem and had a couple of friends tell me the same thing from their experiences. When I removed the front panel of the front loader, I was shocked to see over 4 inches of lint and a few coins in the bottom of the dryer and inside of the heating element assembly. I could see where the lint was blackened and looked like it tried to ignite. I removed the element and looked at it but couldn't find a break. I tested with my ohm meter with the beep setting every couple of inches and finally found a bad area. Upon closer look and moving the coils the break was evident. I checked the thermal fuse and thermister with the ohm meter and they tested ok. I ordered the original and pricey Samsung heating element from Appliance Parts Pro even though I could get a cheap reproduction for under $10 on Amazon. Sometimes you can get away with a cheap product but I decided that didn't want to have to go through this replacement again. I did a final cleaning/vacuuming of everything that I could reach. I removed the screws on the lint remover/filter assembly on the front loader. I was amazed of how much lint was lodged down in the exhaust pipe. I put everything back together and after drying 6 loads of clothes everything is working fine. I believe that the Number 1 reason a dryer fails is from the excessive buildup of lint that escapes back into the dryer when the exhaust vent pipe becomes blocked with lint and the exhaust pipe has too many tight bends. I removed the cheap foil vent pipe and had a tremendous buildup of lint. I replaced the vent pipe with a round sheet metal pipe to eliminate a few of the bends. I would recommend that if you have a dryer that is more than a few years old, to take off the front panel and clean/vacuum the inside of the dryer where the heating element is located before the element breaks or starts a fire. Also, clean the exhaust vent pipe every year or two.
