How to Troubleshoot & Replace Whirlpool AP3874047 / 280148 Dryer Thermal Cut-Off Fuse And High Limit Thermostat Kit

Replace the thermal cut off and the thermostat 

I replaced the heating element and the thermal cutoff and fuse since I had the dryer open and these things seem to be typical problems for whirlpool dryers. I also removed the back panel and gave it a thorough vacuuming as there was a lot of lint build up. The parts arrived incredibly quick, barely 2 days with the cheapest shipping option. Appliance Parts Pros rocks! 

This is a Kenmore washer about 8 years old, I had to release top panel clips, raise the top panel, remove the door panel, the lint trap cover, removed back panel, the front drum support panel, released the drum belt by releasing the belt idler arm, then removed the drum and felt seal. Used multimeter to test for continuity of the heating coil and the two heating element thermistors. Removed the element cover and verified the element was separated on the bottom coil. The cutoff thermistor was suspect so decided to replace both along with the coil. I disassembled the washer by myself and this is not an easy job for a 77 year old with arthritis, in a limited space area. I had one of your troubleshooting guides, so it only took 30 minutes to disassemble, but over an hour to put back together. Son's extra hands for me was a must to reassemble. This is the 3rd time I've used your parts, and they always come as shown and they have always arrived in less than two days, once within 27 hours, which is a great benefit!! I once ordered a part from Sears and it took 4 days on an expedited order. I always recommend you to friends, but I don't offer to help them, only to supervise! Thank you for great service and user friendly website. 

Replaced all three parts with no problem and the error has not come back after seven loads. 

Removed and replace: Thermal fuse Thermal cut off limit Heating element 

I ordered the heating element which was not bad but they get corroded after that many years and they're not as efficient if you get a new one it will save on electricity the thermal fuse was blown that is why it wouldn't come on but you might as well change all three items they're just bolted together very simple quarter inch screws very easy to take apart very easy to reinstall on a Whirlpool that I have you only take the front panel off the very bottom with two screws and everything is right there I'm sure it's different on other dryers but they work the same it's always good to buy OEM products everything fits exactly like it did before if you're doing this job make sure you get the little pigtail I realize it's $ but when you look at your other connections right at the heating element you will see how hot they've gotten over the years to where they're brittle and ready to break two of them would be best but you can get by with just one 

Installed new heating element. Only replace Thermal cut off & Dryer thermostat , because shared same housing . 

Thermal cutoff - thermal fuse - and thermistor 

I emailed customer service to see if they had a video on how to access the heater element. They provided the exact video I needed. I ordered the parts and they worked perfectly. I also appreciated the fact that ALL parts were factory OEM. 

Replaced the heating element that was bad, Replaced the thermostat and thermal cut-off. The shipping was fast which solved all my problems. This is a great site and love the videos. Saved me from an expensive service call.
