Could be a defective thermostat but not the most usual problem. The most common and 1st place to look would be to make sure that the exhaust hose vented to the outside of the house is clear of any obstructions such as lint. If this is extra long or has allot of bends in it the dryer can over heat and the thermostat is just doing its job. Whatever you do, do not bypass the thermostat as you could create a fire hazard.

YOUR DRYER HAS A FUSE AND NEEDS TO BE CHECKED. SEE IF IT IS LOCATED SOMEWHERE WHERE THE POWER CORD COMES IN AT. IT SHOULD BE CLOSE TO THE MAIN POWER COMING IN OR MAYBE EVEN IN THE CONTROL PANEL AREA.

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

I have a dlg5932w dryer that will not heat. From reading posts, it sounds like I need to reset a safety thermostat switch. How do I find it so I can reset it.


Unplug the unit. Remove the top cover by unscrewing the 3 screws in the back and sliding the cover back and up. At the control board, disconnect all the wires from the board, remove the screws holding the panel and pop the panel off. Remove the front panel of the dryer. Down on the right bottom corner inside the dryer, look for the large round tube where there are 2 sets of wires connected around it. There are 2 high limit switches, one on top right and one on the bottom left. The high limit switch on the bottom left has the reset button in between the wires. Push it and you should hear a click. That will reset the switch. NOTE: this is only a temporary fix. The manufactures recommends replacing that switch if it should trip because it will trip again. Good luck

BOSCH DRYER #WTL5400UC Thanks Gentlemen, All power is there, all lights are on, but..........hit the start button and nothing happens. Please Help


Hello,

Welcome to FixYa.

Based on what I've read of your post...I'd suspect the hi-limit thermostat is tripped if it is indeed a WTL series Bosch.


I'm not clear as to whether or not you located the hi-limit safety, reset it, or ruled it out so I'm going to explain what to look for and what to do when you get there.

**Unplug the unit from the wall or switch off the breaker...safety first**

Once the dryer has been disconnected from any power, remove the rear panel...

i.e.

7209371.jpg
Once the panel has successfully been removed, you'll see the heater with the Hi-Limit and NTC attached. The Hi-limit is the thermostat with the red button in the center...

i.e.

03efa1a.jpg
push it in to reset it. As you can see by the images I've provided, if you have a multi-meter or ohm meter you can verify the proper values of the listed components.

If the hi-limit is tripped, obviously something triggered it, you can check the possible culprits such as the NTC's or heater with the info I provided above as I alluded to.

( Even so, I'd suggest running it through a cycle or two and monitor it's performance, it may have tripped simply due to poor air flow from a large load etc. and therefore nothing is actually wrong...human error )

You may run the dryer momentarily without the rear panel in place provided nothing electrical has been disconnected, don't attempt an entire cycle, just witness the heater functioning, but it isn't recommended for much longer than a minute or two.

Thank you for choosing FixYa and please let me know what you find out or if you indeed require further assistance. Good luck.

Regards,

Macmarkus :)

The dryer has no heat anymore. Cleaned out the ducting in the machine and the exhaust ducting. Runs normally, less the heat.


Hi,
On electric dryers the problem can be caused by many different things that can go bad...and often it is a combination of things that go bad and cause problems.

The heating element can go bad but it very often does not. It is controlled by a thermostat... this often goes bad and then it caused the high limit to cut out the heat... this burns that out... so if the thermostat is bad then you also need to replace the high limit...

On many newer dryers there are sensors that also can go bad...if they are telling the dryer that it is already hot inside then the heat will not come on...they can be checked with an OHM meter...
Like wise if the sensor says it is too cool inside then the heat stays on till it trips the high limit...

Of course if your dryer was all plugged up with lint then maybe it just tripped the high limit and that is all that you need replaced...

So you can see that the best buddy of the troubleshooter is the OHM meter to check through the circuits and see why the dryer is not heating...there are many possibilities...
check out this electric no heat tip...

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

Hello- The first thing to check, if you haven't already, is how well the dryer is venting. Make sure there are the flexible duct from the dryer to the wall is not crushed or crimped in any way. As well, with the dryer running, go outside and locate where the dryer exits the wall and feel how much air is coming out. Is should be blowing strong out of the vent. If not, and if the ducting travels a long distance through the walls you may want to have a duct cleaning service out. If there is a lot of lint build-up in the vent then the dryer will have trouble evacuating the hot air and the unit can overheat causing the thermostat to trip. If all your venting is ok but the thermostat is still tripping then replace the thermostat. Hope this helps, best regards.

Dryer went off for overheating won't start again . Reset is ok next to the burner.no point to point diagram , sequence of operations , or component i.d. beautiful machine.........


HI, if this has occurred, the issue may be a faulty high limit thermostat or, the thermal fuse has been tripped, due to an obstructed ventilation system(exhaust assembly).

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.

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

NOTE***

Make sure the dryer vent hose, as well as the rest of the vent duct, is not clogged.

Unless regular maintenance is performed, chances are there is a lot of lint accumulated inside the dryer. This might affect the drying time and could be a fire hazard. Make sure to have your dryer cleaned regularly. Because this might involve taking most of the dryer apart, it is recommended to have a qualified appliance repairman perform this task.

Dryer will run for says then trip off, not the


If it is in timed dry mode, the problem is in the timer, if it is on sensor dry then you may have a clogged line. Easy to check, disconnect vent from back of machine and run it, if it dries without a problem then you need to replace or thoroughly clean venting. If it still does the same thing, check your thermostats, like the cycling thermostat, that is what advances the timer in sensor dry mode. What do you mean by tripping off? Do you replace the high limit fuse to get it to work again or does it just shut down?
