Question about Dryers

1 Answer

Thermal limiter you answerred a question regarding a thermal limietr that keeps tripping in my dryer. I think i solved the problem by removing several feet of flexible vent in the attick. As a follow-up to your description of the thermostats that regulate the heat: I know the thermal limietr is "one and done" meaning that once it trips it has to be replaced but what about the other 2? If I have already replecde the thermal does that mean that the other two are not functioning? Thanks

In most dryers there are two thermal fuses and two thermostats. If the vent hose was restricted it is most likely that the thermal fuse on the heater assembly has failed . The fuse and thermostat come as a set in that in most cases the thermal fuse blows as a result of the thermostat failing.

The second set of a thermal fuse and thermostat is located on the air exiting the drum closest to the vent and control the drum air temperature. A qualified repair person can easily with power disconnected check these for devices and the one that is open at room temperature needs to be replaced.

Hope this helps?

Components in blue box are the thermal cutoff fuses

Parts below are used in the heater assembly to control the heater maximum temperature. If the thermal cutoff fails the thermostat is also replaced. These parts come as a set.

You may have a bad timer: Also, there may be a separate thermal fuse for the motor, usually an inch long white plastic one attached to the blower housing.

there are several issues that can cause this most common is the vent restricted backing up heat in the dryer if its as old as you say you need to check the whole vent system it has to be 4inches dia all the way if its mashed or drooping under the house its restricted if its folded over or mashed behind the dryer its restricted the thermal limiter is a safety thermostat it opens about 300 degrees to prevent fire the dryer has three thermostats an operating thermostat a safety thermostat and the thermal limiter if the operating thermostat fails then the safety thermostat takes over and cycles on about 165 on and off if both thermostats fail then the thermal limiter opens about 220-300 depending and it doesn't reset and cuts all the power to the dryer till a tech can check everything i just told you about so if your vent is clear and the best way to vent is 4inch pvc drain pipe 90 it up behind the drier then connect with a short peice of metel vent then just replace all three thermostats

You can get the thermostats individually. High limit is part number 6931EL3001E and the safety is 6931EL3003D

I had the same problem last month. My heater element broke in two places. This created an electrical open that prevented the heater from functioning. I replaced the heater element and my problem was solved.

In order to check your heater element: With the machine unplugged, disconnect one wire to the heater element and then use an ohm meter or multimeter across the heater element lugs to read resistance. Infinite ohms = open circuit.

DRYER STOPS/STARTS DOESN'T GET HOT ENOUGH


dryer duct blockage caused thermal limiters to trip. four t 20 screws remove the heater bank cover on the back of the dryer. unplug the dryer. unplug the dryer. did i forget to mention, unplug the dryer? remove the heater bank cover, and press the three red buttons in the center of each thermal limiter. at least one of them should click when you press it. replace the cover, plug the dryer in. it will now heat, but if you dont fix the blockage it will trip again.

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. It is an easy and cheap repair to make.

jahn27_43.jpg

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.

It got extremely hot and tripped the breaker. The coil is not shorted, so I'm guessing a switch or heat sensor is. What do you think? It is model RED4400


There is a high limit thermal fuse on the rear of the machine.
Test it for continuity.

My dryer will run but will not get hot. The trouble shooting guide says that on of the two house fuses in the circuit may be blown or the thermal limiter is tripped. Where are the fuses in the dryer. I...


First id make sure you have both phase of AC power coming into dryer.
Go to your house panel and reset yoru house breaker for the dryer. If in the USA the breaker should be a 240volt / 30amp breaker. It will have two breakers tied together at the trip switch.
If AC power is good at the dryer outlet then it could be one of the followings.

  1. Open Thermal limit fuse or trip switch.
  2. Open Heater Element.
  3. Control board is faulty.

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.

Our Kenmore 87042 thermal limited tripped. Can we


This is repairable. Most dryers have a thermal fuse, or limiter, 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.

Whirl pool elect dryer keeps tripping breaker


Ok, this is the result of a failed High limit thermostat. you should replace this failed device asap.

Check for continuity in the thermal fuse as well. replace if no continuity is found.

Hey billybob40s,
Does the dryer trip the circuit as soon as you push the start button or does it take a while to trip??

Hotpoint aquarius tdc32 condenser dryer keeps cutting/tripping out after 5 minutes usage. Press the start button immediately after and won't start. Have to give it 10 minutes or so before starts up....


Hi,

It may be necessary to clean the condenser unit/module (heat exchanger). Often lint would accumulate reducing the efficiency of the condenser causing the temperature internally to rise above specs. Thermal cutoff senses and trips the unit.

In some instances, it could be the thermal sensor/thermostat. I think your particular model has two of them. To gain access inside, it would be required to remove 2~3 panelings. A continuity tester is needed to check the thermostats.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
