LG DLE7177 Thermal fuse

I replaced the outlet for my dryer and screwed up two wires. The power source is fixed now (tested and confirmed). However, when I plug in my dryer I get nothing but the inside light coming on when the door is open. Someone suggested a blown thermal fuse. So I called a repair man. This repairman, who could barely get my unit opened and had to call a co-worker for advice, just left and told me that my LG DLE7177 dryer does not have a thermal fuse. Rather, he stated my mother board is bad and will cost $300-400 to replace. I called LG and they said my dryer does have a thermal fuse. Can anyone tell me: 1. How to get to my thermal fuse? Meaning where is it located? I currently have the dryer top off. 2. How do I check it to see if it is bad?

Roper dryer #RES7648JQ0 will not start


Your dryer very likely wont start due to a bad Thermal Fuse. This video I have attached shows how to replace the thermal fuse. I know the video says Whirlpool dryer, Whirlpool is the maker of the Roper brand and it should be exactly as shown in the video. The video shows using a jumper wire to bypass the thermal fuse if you have such a jumper wire it is effective to check if the fuse is the problem,if not just temporarily connect the 2 blue wires together and test if the dryer starts. BE ABSOLUTLY SURE BEFORE EITHER USINGA JUMPER WIRE OF CONNECTING THE BLUE WIRES TOGETHER ***DISCONNECT THE POWER TO THE DRYER*** USE JUMPER,OR CONNECT WIRING THEN RECONNECT POWER TO DRYER so it may be tested to see if the dryer starts.

I base my diagnosis on my 30 plus years as a appliance service technician.

Thanks,Gene

Wed6400sbo dryer wouldnt heat now start button wont work


check thermal fuse. Testing a thermal fuse

Note: Disconnect the power source to your dryer before you conduct this or any other test. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel. Testing a dryer's thermal fuse is much like testing its thermostats. Follow these steps to replace your dryer's thermal fuse.
The wires leading to the thermal fuse are connected using metal slip on connectors. Remove the wires by pulling on the connectors, and not the wires themselves. It may be a good idea to use a pair of needle nosed pliers to help you.
Set your multimeter to the R X 1 setting. Take each of your meter's probes and touch one to each terminal. You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermal fuse should produce a reading of zero. But if a thermostat is tested when it is heated to its limit, a reading of infinity should be produced. We strongly recommend that you test your thermostat at room temperature.
If the test you conduct with your thermostat does not produce these results, then you should replace the component.

I have a Kenmore Dryer, Model 96292110. It runs, but it does not heat the air. I have checked the circuit breakers. They are fine.


Hello,

If your Maytag dryer has mysteriously stopped producing heat, a blown thermal fuse may be the cause of your problem. In Whirlpool dryers,thermal fuses are safety switches that are designed to disrupt the flow of electricity to your dryer's heating mechanisms once the dryer reaches a predetermined maximum temperature, usually somewhere around 180 degrees F.

Thankfully, troubleshooting the thermal fuse in a Maytag dryer is easier than it sounds.

Instructions And Things You'll Needed.
  • Screwdriver,Towel,Electrical tape,Replacement thermal fuse, if necessary.
1 Clean out thelint screen in your Maytag clothes dryer. Lint buildup can cause your dryerto overheat, triggering the thermal fuse to disrupt power to your dryer'sheating mechanisms. Take the lint screen out of your Whirlpool dryer and washit in warm water. Dry the screen thoroughly before replacing it.

2 Look behindthe dryer to check its flexible exhaust hose for kinks or obstructions.Disconnect the exhaust hose from the back of your dryer and clean out any lintthat has built up.

3 Go outside andcheck your Maytag dryer's exhaust vent for obstructions. Lint buildup, birdnests or other obstructions in the outside exhaust vent can trigger yourdryer's thermal fuse.

4 Disconnectyour dryer from its power source before attempting to access its thermal fuse.

5 Access the thermal fuse in your Maytag dryer byremoving the back panel. Remove the screws that hold the back panel in placeand it should easily come free.

6 Look betweenthe dryer's blower housing and exhaust to locate its thermal fuse. The thermalfuse in a Whirlpool dryer looks like a white plastic strip that has two wiresconnected to it.

7 Bypass the thermal fuse in your Maytag dryer whileyou perform a quick diagnostic test. Use electrical tape to tape together thetwo wires connected to the thermal fuse. Reassemble your dryer and plug it backin. Set the dryer to a timed heated drying cycle and press "Start."If the dryer produces heat with its thermal fuse bypassed, it means the thermalfuse needs to be replaced.

8 Replace a blown thermal fuse in your Maytag dryer.Disconnect the power and remove the back panel. Remove the electrical tape thatyou used to perform the diagnostic test and disconnect the wires from thethermal fuse. Remove the screws that secure the thermal fuse to the dryer anddiscard the blown fuse. Attach the replacement thermal fuse by replacing andtightening the screws. Attach the wires to the new thermal fuse.

Just moved the dryer to new home after having it in storage for 18 months. Plugged it in and it doesn't do anything. Tested house circuit and it is fine. Tested the dryer at the cord connection and it is...


On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

    My frigidaire dryer LEQ642DS0 will not shut off by itself, would that be the timer or the knob? Also if it is the timer, is the kenmore/frigidaire part #131062300 (timer) compatable with my dryer


    Instructions
    Things You'll Need:

    * Phillips and hex nut screwdrivers
    * Replacement thermal fuse
    * Replacement thermostat

    1. Disconnect the dryer from the electrical outlet.
    2. Slide a putty knife between the top panel and front panel on the left side. Slide the knife toward the center of the dryer to release the left-side spring clip. Repeat the process on the right side. Lift the top panel up and rotate toward the back of the dryer. The thermal fuse and thermostat are located along the dryer's back wall, attached to the heating element housing.
    3. Disconnect the two wires from the thermal fuse. The thermal fuse is an inch-long rectangular plastic part, located near the top of the heating element housing. Remove the screw holding the thermal fuse in place. Remove the old fuse. Place a new fuse on the housing and replace the screw. Reconnect the wires to the fuse.
    4. Remove the wires on the thermostat. The thermostat is a black, oval-shaped part located just below the thermal fuse. Remove the screws holding the thermostat in place and slide it out of its slot on the heating element housing. Slide a new thermostat into the slot and replace the screw. Reconnect the wires.
    5. Lower the dryer's top panel and press down until the spring clips lock into place. Plug the dryer back into the electrical outlet.

    Wont heat


    Hi


    Thanks for using FixYa. No Heat issue in dryer is usually caused due to three things mainly: Thermal Fuse, Wiring Harness and/or Heating Element. Start with checking the Thermal Fuse which ismounted inside the back cover panel to the exhaust duct and is mounted in white plastic housing. If thats fine then the Heating Element should be checked. Please do revert for further assistance.


    Thanks

    Will not heat


    Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

    A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.

    Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.
