Question about Dryers

1 Answer

Problem with LER3624EQ1 Dryer. I have replaced the high limit switch twice and the thermostat. The dryer will run with hot air for a few minutes and then back to cold air with a new high limit switch. I have checked and the thermostat and thermal fuse both have continuity. The high limit fuse keeps tripping. I ran it for a few seconds with a jumper on the high limit switch and it heats up, no problem. Any idea what I should check next?

The first thing you need is a multimeter, get one at Walmart you don't need a expensive one and the an be used for a lot of things around the house, pull wires off heater turn meter to ohms check between frame of dryer and each terminal it should show nothing if you are showing anything on the meter get a new heater

    I got a multimeter that beeps. On the thermal switch, that I know is good, it beeps. On the heater from post to frame it does not beep. Does that mean the heating element is bad?

SOURCE: Hotpoint NVL333EY Electric dryer blows thermal fuse

I had the same thing happen, I replaced the thermal cutoff and made sure no lint build up. It lasted a week then blew again. I then replaced it again and got to thinking why it would blow. I then took apart the exaust inside the dryer running fron the drum to the motor and right before the motor was a build up of lint ane particals that was almost like compressed sawdust which was blocking half of the line. I cleaned this out and it seemed to work much better.

SOURCE: Thermal limiter stops dryer; replaced multiple times. Dryer dead.

I think you are working on the wrong end. Check the fan and inlet ductwork of the dryer, if the air isn't moving properly, it will not move enough to keep the coils and limiters cool and they will fail after working properly a few times.

I think you are on the right track with a faulty high limit switch. When i serviced these units we always replaced the operating thermostat and the high limit switch together they came in a kit. The operating thermostat in theory should never let it get hot enough to trip the high limit switch, which is really just a safety backup for the operating thermostat. Get the kit and replace both, and also make sure your exhaust vent going outside has good flow at the outside vent,a restricted vent system will cause similar issues.. Good Luck

The air flow past the thermal fuse is too hot. The air flow cools the heater coil area. Check the air passages from the lint filter to the heator coil housing for lint balls blocking the flow and letting the area around the fuse get too hot.

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.

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.

    • Install the thermostat in your dryer's heater element housing box. Be sure your dryer is unplugged during installation.

    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 whirlpool dryer wont start, I replaced the start switch and the door switch seems fine. I hear a ticking noise


    The door switch may not be making contact. All dryers also have a High Limit thermostat that shuts down the dryer when too hot. The high limit thermostat should reset when the dryer is cooled off but may be defective. If the dryer is electric, 110 volts run the drum motor, and the other leg of the 220 line is for the heating element.

    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.

    jahn27_559.jpg


    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.

    My model LER3624EQ1 shuts off after a few minutes of running, timer is still running. I have cleaned out the dryer lint and hose to the outside.


    It sounds like you could have a hi limit thermostat problem. This can cause serious problem such as dryer fires since the element may still be operating without the air flow needed while the dryer is running. Located on the element housing, this thermostat gauges the temperature of element and shuts it off when the desired temperature is reached. part number is 694674. And should be replaced by a technician. Hope this helps

    Thanks

    Whirlpool LER4634EQO Runs for about 2 minuts and shuts off.


    It is possible your Cycling Themostat is not working properly. It determines at what temperature to turn heat on and off to maintain a consistent dryer temp. The High Limit Thermostat would turn off the heat but your dryer would still run. That leaves the Thermal Cut Off which is turning off your dryer. It might be faulty and turning off at too low a temp, or it might be doing it's job. In that case something else is wrong. If you can check the exhaust air temperature at the dryer, it should be under 175 degrees. If you are absolutely sure the vent is clear, then replace the Dryer Cycling Thermostat.

    Kenmore 90 series electric dryer. Buzzez when you press the start. Sometimes it runs for a couple minutes then shuts off. is this the motor or a start capacitor?


    Thermostat controls heat. There is also a motor centrifulgal switch, in the element circuit, that the motor closes to insure the motor is turning. Try another heat setting. There is more than one thermostat. You may have blown the 'thermal fuse' too, which requires replacement.

    Tripped high limit. Must clean the lint filter and the exhaust vent tube and all the way in to the dryer. Hot air exit is restricted.
