Replace fuse dryer model GEQ8821LLO

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

    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.

    My gas clothes dryer is working,but it is not blowing hot air

    The thermostat or thermal fuse could be blown. Usually happens when lint buildup blocks the exhaust exit & the heat stays inside the machine. So to prevent a fire, the thermal fuse or thermostat blows. You would have to enter your model # on google to find links to parts breakdown.

    I have a whirlpool gas dryer model LGR5620KQ1, I replaced the thermal fuse, still have no heat

    When you push start look in the front lower cover and see if the glowing igniter glows. If it does then there is a flame sensor on the side of the burner that probably is bad.

    I have a Kenmore Series 70 Dryer and I changed the thermal fuse got hot for a few minutes the model #110.74722400

    The cycling thermostat must also be replaced when replacing the thermal fuse. The cycling thermostat's failure to cycle off the heating element results in overheating of the dryer which consequently blows the thermal fuse open.


    Replacing only the thermal fuse should the dryer stops running and fails to start will result in its premature blowing or even the thermal cut-out (cut-off) located on the heater duct. Like the cycling thermostat, the high-limit thermostat must also be replaced once the thermal cut-out blows open. Refer to the parts diagram in the link below and look for item numbers 31(thermal cut-off), 34(hi-limit thermostat), 39(thermal fuse), and 41(cycling thermostat.

    Dryer not heating checked element for continuity it was good. Any ideas?


    If it is turning but not heating, check the thermal fuse if present. The fuse is also tested checking continuity. If the fuse is OK, check the thermostats in the heater assembly. If the thermostats are good, they will read zero or very low impedance at room temp.Depending on the model there are two or three thermostat/thermistors in the appliance.

    My lg gas dryer doesnt get hot.


    As first thing try replacing the thermal fuse.

    The thermal fuse is located in the blower housing, near to the exhaust at the back of the dryer. The thermal fuse cost is only few dollars. Before replacement it can be tested reading Ohms with a multimeter. If the multimeter set on impedance reads infinite Ohms (No continuity, same as on air), then the fuse must be replaced. A good fuse must read low or zero impedance.

    If the thermal fuse is OK, the next parts to test are the thermostats. On GE gas dryers there are at least two thermostats. One is a control of themperature, the other is an high limit. High limit is hosted on the blower housing, near to the thermal fuse. There is one or two thermostats near to the blower wheel. Often there is a safety thermostat near to the burner. To get details on the specific model check the schematics tucked inside the appliance or available online.
    The thermostats are tested reading Ohms at room temperature. If any of them returns no continuity at room, then the thermostat is faulty and must be replaced.

    If the thermostats and fuse are OK, then the next step is checking valve and igniter. The igniter or glowbar is tested energizing it and observing if there is spark. The valve is tested reading Ohms on solenoid with multimeter set at Rx1. If the solenoid has no continuity, then the valve is faulty. There is also a flame sensor that can be tested reading impedance or jumping its contacts.

    If all the parts listed above are OK, then wiring and electronic timer control board must be tested reading voltages at contacts.

    The problem is likely the thermal fuse or one of the thermostats.

    Apart replacing the part, ensure that the hoses are not blocked , and that there is no lint inside the machine. This may have caused the fuse blowing.

    Here a general diagram that can help you in identifying parts.

    All tests must be done by a trained technician.

    To get a technician on site , or to get a quote on repair ring the number listed on the owners manual.You can also get an US technician contact using our directory:Contacts.

    To get parts ring GE at the number on manual.

    For Dryer Model LER7646EQ1, dryer runs but no heat, It could be the heating element, the thermal fuse or other. Also the dryer has been running hot.I do not know how to remove the front panel

    This sounds like a faulty thermal fuse or heating element. The fact that you said the dryer has been running hot could indicate that the heating element was making contact with the heater box or the high limit thermostat is faulty. Both the thermal fuse and heating element can be tested using a multimeter or ohmmeter and checking for continuity. A lack of continuity means a faulty component. When necessary to replace a thermal fuse it is best to change the high limit thermostat as well. They will sometimes come as a set from a parts supplier. Really sorry for your trouble and I hope this helped. Best wishes.

    Please check the following things that could stop a gas dryer from heating:- glow bar igniter, thermal fuse ( not all models ), coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.
    A page for checking gas dryers is here.

    Please do rate the solution if the issue is resolved or else revert for further assistance.

    Whirlpool Dryer blows cold air when starting no heat

    Did the fuse blow out? If so then the heating element is shorted out. This happens frequently when they fail. If the fuse is blown check the condition of or change out the heating element.
