    Hey mark92230, thanks for the suggestion. We cleaned out all the ducts with shop vac and compartment where lint screen sits, still went back to same thing. Thanks for your help though.

  • mark92230 Apr 12, 2011

    you're welcome . I did want to tell you someone else was having the same problem, they cleaned everything first and then they had to replace a limit switch located down by the burner. Sorry I couldn't help you more.

Timer goes to 99 minutes and clothes note drying all the way


Hi cayjr1

Clogged Vent
If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.
When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)
The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.
This cycle continues until the clothes are dry.
But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
Heating Element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.
Cycling thermostat
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork . This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

Dryer is running, but heat will not turn on


There are several things that can prevent a dryer from not heating.. Unplug Power Before checking.
Electric Models
1- Power- Your dryer runs on 220volts. 110 runs the entire dryer and 110 runs just the element. Your breaker may have half tripped. Check to see if you are getting the correct amount of power by using a ohm meter. Also check the power cord for burn marks on the plugin and the cord itself.
2- The thermal fuse can prevent this from heating. The thermal fuse is a sensor on the blower housing the measures the temperature of the air. There is a cycling thermistat near the thermal fuse. If the dryer temp gets over 190-220 degrees the thermal fuse will blow to cut power to the element to prevent fire. You can test this by using a continuity tester.
3- High limit and/or thermal cutoff. These are both sensors on the heating element housing. Thermal cutoff is at the top and the high limit is near the bottom above the heating element connectors. Test these with a continuity tester.
4- Heating element- Just below the high limit on the heater housing. Test for continuity.
5- Motor- The motor has to reach a certain rpm to activate a sinfrigrial switch inside the motor. If the rpm is not reached it will not allow current to go to the element.
6- Timer- Make sure you are trying this on timed dry. Sometimes people use air fluff and forget to change it back. The timer could also not be sending current to the heater.

Gas models
1- Electric ignitor- Inside the flame tunnel inside of dryer near where gas line hooks up. Usually if it glows than it is still good but check to see if it is sending and amp signal to the heat coils.
2- Heater coils are two valves that open up when the ignitor send signal saying the ignitor can ignite the gas. Heat coils will not open to send gas if it does not receive a signal from the ignotor. They look like two round disk with two wires running from ignitor.
3- Flame sensor- Change if you change the heater coils. The flame sensor could not be detecting the flame inside so it shuts down the ignitor.
4- Motor- See above
5- Timer See above

If you have any further questions or need further assistance please feel free to comment me back.

Drum turns but no Heat problem!!


Brian, if the glow ignitor comes on for a minute clicks and goes off then you need valve coils. if no glow at all could be ignitor or thermal fuse.

Dryer drum rotates but does not dry. No heat.


The problem is your dryer coils are failing. They tend to fail as they heat up. The parts are inexpensive and easy to test and replace.There is a video at www.appliancehelponline.com/servicemanual.html this will walk you thru the troubleshooting of these components. It may be a different model but the troubleshooting will be the same.You can also enter your model # for diagrams and illustrations. Not all models are available. If you need help disassembling your machine there are videos of this also for most styles.

Dryer runs but won't heat


As the clothes gently toss about inside the drum, a temperature control thermostatic disk regulates the heat. It is set for 160f for cotton and it mounts on the blower housing. As air is drawn into the drum and out the backside of the dryer the heat is regulated by this control. It sends 120 volts to the gas assembly. Right next to it is a fuse. The duct fuse is set to blow at 250f. Should that control fail to open and allow for heat to build to abnormally high temps. Note: the fuse will kill the heat source only on most dryer, the dryer will however continue to run. Lint and vent blockage can restrict the airflow and make the heat inside build to dangerous levels.The control thermostat powers up the heat for a minute then shuts down for a few minutes, then repeats this all throughout the drying process, the gas does not stay on! That would burn the clothes. If both of those items check ok and the dryer vent and lint has been cleaned, I next take a look at the gas assembly. I check the flame sensor first. If the flame sensor is open the ignitor will not glow. If that turns out to be good I next check the ignitor itself for continuity. If it turns out to be good I replace the coils. Those coils cannot be checked because they do not act up until energised. Sometimes the coils will work, get hot and fail, cool down and work again. I have some repair photos: HERE

Whirlpool gas dryer Model #WGD5530SQ0 not heating properly


If your dryer heats when you first turn it on and after a few minutes it does'nt. check the ignitor to see if it is glowing. It should glow bright then you will hear a click and the burner will light. If the ignitor glows bright but you hear a click but no flame and if you watch this for several minutes and this process continues of glow then glow goes out no flame, then you have a bad burner coil. There are 2 black solenoids sitting on top of gas valve. One of them is shorting out after it warms up. Replace both solenoids. You can usually get them as a kit from parts store.

No Heat


Hello
Welcome to Fixya


Remove the vent line from the rear and try the dryer.
If it heats then that means there is a clog or kink in the vent line blocking the vent air from exiting which will stop the dryer from getting hot!
If not then it's another one of these problems.

Defective Ignitor (Gas Only)
When heated the ignitor used on your gas dryer must obtain a specific high temperature
in order to activate the flame sensor. This ignitor is fragile and susceptible to cracking.
A hairline fracture that is barely visible to the naked eye is enough to change
the resistance of the ignitor to a point that is will not work properly.
You can test the resistance of your ignitor. You should get a reading of 50-400 ohms of
resistance.

If the ignitor gets hot and then goes off after about 10-15 seconds and there is
no ignition, the problem is probably not the ignitor. It is most likely the gas valve
coils that are defective.

If the ignitor comes on and stays on, it is the flame sensor that is defective.

If the ignitor is not getting hot it could also be one of the thermostats that is defective.
The power for the ignitor is passed from the timer, through all of the thermostats,
limit switches and fuses to the ignitor. So if you are not getting power to the ignitor
during ignition, you should check the continuity of the individual thermostats and fuses.
DRYER DOES NOT HEAT



Defective Gas Valve Coil (Gas Dryer Only)

If the gas dryer will light once but will not relight until it cools down, it is likely the gas valve coils are faulty. These coils loose some strength when subjected to heat. When they become old, the addition of heat may be enough to prevent them from opening the gas valve when hot. However the coils still work when when cool.

An easy way to diagnose the coils when the burner is not lighting, watch the ignitor. If the the ignitor glows for 10 to 15 seconds but no flame is created, then the coils are faulty. If the ignitor is not glowing the problem is elsewhere.

Recent Customer Symptoms:
The dryer burner doesn't always come on when starting. If the burner does come on, once it goes off if won't come on again until the dryer cools down.



Defective Flame Sensor (Gas Dryer Only)
The flame sensor's job is to monitor the ignitor for sufficient heat
to ignite the gas. A properly operating flame sensor will pass a
continuity check under room temperature.

Common Symptoms
If the flame sensor is defective in the open position,
the ignitor will not get hot when the dryer is started.
However, if it is defective in the closed position the ignitor
will get hot, but the flame sensor will not allow the flame to ignite.
In this case, the ignitor will usually stay hot for a long period of
time.



Defective Thermostat
The thermostats are responsible for maintaining the proper temperature
in the dryer. Check the exhaust temperature of the dyer and if the
temperature is above 150 degrees, you will most likely need to change
the operating thermostat.

The thermostat can also fail in the opposite mode.
It can prevent the element from heating at all.
A failed continuity check at room temperature will verify this condition.

There are some special thermostats that are single pole double throw.
These thermostats are often used to control the timer when set to the
Automatic Dry cycle. If the dryer timer will advance in the Timed Dry
cycle but not the Automatic Dry cycle, then the thermostat could be the
problem.


Defective Thermal Fuse
The thermal fuse is in series with one leg of power to the motor.
If the fuse is open (no continuity) the motor will not run.

Location:
The thermal fuse is located in different locations according
to the model and brand of dryer.

Solution:
Check the thermal fuse for continuity with a volt/ohm meter.
If it is open, it will need to be replaced

Whirlpool dryer LGR7646EQ3. Burner lights before pushing start.


The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse. If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the ignitor and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot ignitor and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly.
