Those 250 degree thermostats will fail frequently. That is why they come in the package with the thermal cut off. You can reset the thermal cut off by Slamming it on a hard surface, did you know that? What you need to do is determine the root cause of why that dude keeps blowing. The top 2 reasons that small puppy will blow is a stopped up vent and a stopped up filter housing. You will need to physically remove the filter housing to get it right.

    Strange. That temp switch is not the problem. I have never seen one go bad. The 4 wire tstat that has the small 2 wires on top and the bigger red heater wires that carry the amps is what usually is the probo. Those can be bought cheap.

Replace fuse dryer model GEQ8821LLO


Hello;
My name is Peter. I am a retired field service appliance technician.
You never explained what the problem was. Dryer not running? No heat? Dryer shutting down. It could be as simple as cleaning out your dryer hot air distribution manifold. A dryer will not run if you do not have good air flow due to lint blockage. A dryer will not run if you have a bad door switch. You can Ohm components out with a multi-meter, setting the meter to the lowest Ohms (Omega Symbol). You should get a reading of "0" if the component is good.


1.) Dryer Door Switch - This switch replaces your dryer door's switch.
  • You may need to remove your dryer's lint screen and lint screen housing before lifting its top panel to reach its existing switch.
  • Be sure your dryer is unplugged during installation.
This Dryer Door Switch part #3406107 Cost $20.00

Dryer Door Switch - Unplug the dryer before replacing the door switch.
This Dryer Door Switch part #279782 Cost: $22.00


Thermal Cut-Off- This component is located on your heating element housing,. you may be able to access it at your hot air distribution manifold in the back of your unit.
  • When replacing your dryer's fuse, replace its thermostat, too. The thermostat should have prevented the dryer's existing fuse from blowing. The high-limit thermostat is functional to 250 degrees (Fahrenheit) and the thermal cut-off fuse to 360 degrees (Fahrenheit).
  • Install the fuse in your dryer's heater element housing box. Be sure your dryer is unplugged during installation

  • Part #: 3977394 Cost: $33.00

    The high-limit thermostat replaces your dryer's thermostat.
    • The thermostat is functional to 250 degrees (Fahrenheit).
    • Install the thermostat in your dryer's heater element housing box. Be sure your dryer is unplugged during installation.
    This High-Limit Thermostat part #3390291
    Hot Air Distribution Manifold:
    This is in the back of your dryer and easily unbolted. If you are plugged up with lint your unit will shut down. Remove this component and clean the lower discharge end.

    Does the Kenmore Series 700 dryer use circuit breakers or a thermal fuse to shutoff the heating element?


    All Kenmore Electric Dryers use a thermal cut-off or thermal cut-out, hi-limit thermostat, and a cycling thermostat apart from the motor centrifugal switch as parts of the heating circuit. The thermal cut-off/thermal cut-out and the hi-limit thermostat are located on the heater duct/element duct while the cycling thermostat is located on the blower housing.

    The thermal cut-off/cut-out serves as a safety measure and blows open should the dryer overheats or should the hi-limit thermostat fails to cut off power to the heating element. Check the continuity of the thermal cut-off/cut-out and if open, replace it including the hi-limit thermostat.

    Electric dryer spins no heat, replaced heater element and high limit thermostat, tested thermal fuse and it does have 0 ohms, thermistor reads ~50 ohms.


    in addation to checking the high limit t-stat have you checked the thermal cut off (the small t-stat) on the heater housing where the element fits into, the high limit t-stat and the thermal cut off BOTH shoud have 0 ohms (the thermal fuse is in the blower housing) the cut off is on the heater box, if you have checked those to be good, check that the heat relay on the control board is closing and sending power to the element, if not replace the control, if all above are good then the motor switch is bad and not sending power to the element(thats a built in safety feature so the dry would never heat when the motor isnt running)the element of course heats only when 240 volts ac is to the element ,120vac from the relay on control through the high limit t-stat then through the thermal cut off finally to the element and 120vac from the motor switch for a comined 240 vac

    No a kenmore 80 series dryer will not heat . if the heating elment is good & fuse is good what else could be the problem


    The heating circuit is basically composed of the heating element, thermal cut-off, high-limit thermostat, cycling thermostat, and the motor centrifugal switch. The problem is very likely in the thermal cut-off and the high-limit thermostat located on the blower housing. The thermal cut-off blows when the high-limit thermostat fails and cuts power to the heating element. Both the thermal cut-off and the high-limit thermostat need to be replaced if the former is blown open. Click on the link below for the detailed instructions in troubleshooting this kind of problem.

    Where would the fuse be and how hard to get to, is it in the upper unit? From behind? or lower unit? Running but no heat.


    The problem is obviously in the heating circuit which is basically composed of the heating element, thermal cut-off, high-limit thermostat, cycling thermostat, and the motor centrifugal switch. The most common part that causes the dryer not to heat is the thermal cut-off and/or the high-limit thermostat. Verify this condition by bypassing the said components.

    Disconnect power then access the thermal cut-off (cut-out) and the high-limit thermostat. Disconnect the wires of each component then connect them together and insulate it properly. Reconnect power then start the dryer. The problem is indeed in the thermal cut-off (cut-out) and the high-limit thermostat if the dryer heats up. Replace both parts and it should solve the problem. It is an easy and cheap repair to make. Indicate the exact model number of the dryer should you need further assistance.

    Also bypass the cycling thermostat if the dryer still doesn't heat with the thermal cut-off and the high-limit thermostat bypassed. Check the heating element visually for obvious broken or damaged coil. An ohmmeter will be of great help in checking the resistance/continuity of the heating element. Replace the heating element if broken or damaged, NEVER attempt to repair it.

    The problem is likely in the motor centrifugal switch if the dryer still doesn't heat with good heating element and the three components above bypassed. Indicate the exact model number of the dryer should you need further assistance.

    Model RES7745PQ0 works great but no heat... what is most likely the problem... also I checked my breaker so that's not it...? HELP\r\nBest Regards


    The problem is likely in the thermal cut-off (cut-out) and the high-limit thermostat located on the heating element housing. Verify this condition by bypassing the said components. Disconnect power then remove the rear access panel to access the thermal cut-off (cut-out) and the high-limit thermostat. Disconnect the wires of each component then connect them together and insulate it properly. Reconnect power then start the dryer. The problem is indeed in the thermal cut-off (cut-out) and the high-limit thermostat if the dryer heats up. Replace both parts and it should solve the problem.

    The
    thermal cut-off (cut-out) and high-limit thermostat are sold as a kit with part number 279816 and costs about $30.

    In case the dryer still doesn't heat up with the
    thermal cut-off (cut-out) and high-limit thermostat bypassed, bypass the cycling thermostat then replace it if the dryer heats up. Check the heating element for broken coils if the dryer still doesn't heat up with the three components mentioned above bypassed.

    Thermal cut-off blows and high limit thermostat is working with vent clean.Replaced thermal cut-off, high limit thermostat and heating element. Still blows thermal cut-off.


    Any time a thermal cut off blows, it's because the cycling thermostat is bad. When it's bad, the machine cycles off of the thermal cut off rather than the cycling thermostat allowing the dryer to over heat. The thermal cut off is a re-setting safety and is not made to cycle off of. The thermostat you are looking for looks like a high limit thermostat but it cuts power to the element at a lower temp. Around 158 degrees + or - 25 degrees. It's located close to the high limit. It's a normally closed switch that opens on the rise and it will show closed now but the problem with it is that will not open. Replace it and your problem will be solved. Good luck.
