Question about Whirlpool LER4634J Electric Dryer

1 Answer

I have a LER4634PQ1. The dryer works, but there is not heat. I have removed the top fuse that is housed on the heater unit and can't tell if it is the problem. I also removed the heater core with bottom fuse attatched and still can't tell if it is that part/s either. How can I tell what the problem is?

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

  • Part #: 3977394 Cost: $33.00
    25432459-jpgjqed1aonpcy4b0i04xdgb-5-9.jpg Cost: $34.00
    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.

    I have a Whirlpool LER4634PQ1 it was working just fine then all of a sudden the dryer just keeps running the knob on the dryer doesn't move and the air isn't warm. Any suggestions on what to s

    there is a cycling thermostat in line with the high limit thermostat and timer circuit,on timed dry its disabled and the timer will run no matter what,on any sensor dry setting it uses the heat of the element to heat this cycling thermostat to move the timer as the clothes get drier as the heating element heats the timer doesn't move,when the heater cycles off from the high limit thermostat then timer moves again,you need to find out if its a bad heating element,thermal fuse or possibly even a circuit breaker in the homes electrical panel tripped out on one of the 2 phases that gives you the 240 volts required to operate the dryer element,the breaker may not show its tripped,so shut it off and back on and try this first

    Neptune dryer 5500 no power

    This dryer has 2 thermal fuses. One next to the control stat on the blower housing and another on the heater element. You could quite possibly have a bad blower wheel or simply a lint build up cauing over heating. To get inside this dryer you remove the door first. The you can remove the front. Once that is removed you can pop the top and get the front shroud off. You cannot work from behind.

    I have a whirlpool LER4634PQ1 and it isn't

    the lint filter is on top so the fuse is in the back,unplug it,pull it out,remove the vent line and the back panel,also remove the lint filter and the two phillips screws on the top panel.look at the back,you'll see the metal duct that the filter slides into on the left side,now look down and to the right of the duct,you'll see a white piece with two wires going to it,that's the thermal fuse,you have to remove at least one wire when checking the part,pull the wires off and check it with your meter,if it's bad you have to clean out the dryer or it will pop again,take out the other 4 screws that hold the duct in place,pull the duct out and with a vac clean it out,if you have a brush brush out the duct to lossen the lint so it's easier to clean it,if the vent line is a long run from the back to the outside vent i use a leaf blower to clean it out,go outside and make sure nothing is blocking the outside vent,go back inside,stick the leaf blower into the vent line and blow it out.if the thermal fuse is good,go to the right side,,check the heater element,and the thermostats on the heater box.clean out the dryer once every year,you can pull the front panel off and clean out the cabinet too,blow off the motor,you'll be surprised how much lint blows off of the motor,the lint makes it run hotter and the oil leaks out,you can see it on the drum and on the side panel when it happens,all lint will be stuck to the oil.hope this helps.thermal fuse part number is 3392519.if it's not the fuse give your parts store the model number,tell them the part you need and they'll hook you up.good luck.

    No heat

    Good Morning; Thank You for your question. If you have an ohm meter, it would come in handy. The parts you will probably will need;
    279838 Heater element $54.60
    3387134 Control thermostat $21.26
    3392519 thermal fuse $14.58
    To get to the parts, top is lifted by releasing 2 clips at the lf & rf by pressing in and lifting top. Lay back and prop. Now there are 2 screws at the top left and right of the front panel. Remove. Lift front panel off. Remove wires to door switch noting their position. Remove belt noting its position. Lift drum out. You will see the heat element. Use ohm meter after removing wires for continuity. Replace if necessary. The control thermost. is on blower housing. Replace. Thermal fuse is on heater housing, check for continuity. Whether you fix this dryer or install another one. Go behind dryer. The vent coming off of the dryer to the wall outlet must be as straight as possible. No kinks or bad bends. Go outside check wall vent for lint buildup and clean. Hope this helps

    It's either of the thermal fuse on the blower housing or the thermal fuse on the heater enclosure is blown. These thermal fuses are wired in series with the motor and therefore, if any of them is blown will cause the motor not to run and hence the dryer not to work except the controls.

    Disconnect power to the dryer prior to servicing to avoid the risk of electric shock.

    Open the dryer door and remove the four screws located vertically along the inside lip of the door opening. These screws hold the front panel to the front shroud assembly.

    Once the four screws are removed, grasp and press in on the upper edges of the front panel posts then twist it inward to release the clips holding it to the cabinet. Tilt the top of the front panel and move it away from the dryer.

    Bypass the thermal fuse on the blower housing by disconnecting the wires and taping them together or connecting a jumper wire between them. Close the door then plug and start the dryer.

    The dryer should start and heat up if the blower housing thermal fuse is the culprit. Otherwise, the other thermal fuse on the heater enclosure is blown. Unplug the dryer then bypass the thermal fuse on the heater enclosure in the same way the first is bypassed to confirm it.

    Plug the dryer back then restart it. The dryer should start to confirm that the heater enclosure thermal fuse is blown. Replace the thermal fuse (part number 307473) together with the high-limit thermostat (part number 303396).

    Unplug the dryer and unbypass the blower housing thermal fuse then plug it back and restart it. If the dryer fails to restart, replace also the blower housing thermal fuse (part number 33001762) together with the cycling thermostat.

    Reinstall the front panel in reverse steps of the removal steps to complete the repair.

    Removing a part form a Whirlpool Electric Dryer

    The thermal fuse is located on the outside of the blower housing. To get access to the thermal fuse you will need to remove the back panel of your Whirlpool dryer.

    How do you check it:
    Before you do any repairs on your dryer, you will need to disconnect the dryer from the wall outlet.

    After removing the back panel, remove one wire from the Whirlpool dryer thermal fuse and take a reading between the two terminal on the thermal fuse.
    The reading should be 0 ohms, if the reading is infinity, the thermal fuse is bad and it must be replace. When you find a bad thermal fuse, you will need to replace the operating thermostat too.

    The operating thermostat opens at 155 degrees and the thermal fuse blows at 196.

    These means that operating thermostat did not open at 155 and that is why the thermal fuse failed.

    Dryer does not heat up. MOD TEDS840pq1, Electric dryer

    Ist thing to check on a dryer not heating is the voltage at the outlet. Make sure you have 220/240 volts. The dryer can run on 110/120 volts but won't heat. This can be from a bad breaker/blown fuse. On your dryer it is most likely the thermal fuse on the heater housing or possibly the element itself. If you have a voltmeter you can check each for continuity. The thermal fuse is a smaller thermostat at the top of the heater housing.
