Make sure your vent duct is not clogged up. If the machine can't breathe properly it will short cycle the burner.

If this is ok, it sounds like the flame sensor has failed. Also, the thermistor should not read open, it should have some resistence. It changes depending on the temp. Open the back of the console and you should have a tech sheet that gives all the readings and diagnostic checks.

Post back to this thread if you need help going through it.

There should be a tech sheet in the console. You probably have a blown thermal fuse. It is mounted in the air duct coming from the blower housing and has two blue wires going to it.
Post back with the complete model number from the decal inside the door if you cant find the tech sheet and I will see what I can come up with.
Thanks/Mike

I would like to thank the ones who responded to giving me a 'hand' in repairing my dryer. I did like you said & changed out the coils & now the dryer is working like it should.

SOURCE: Kenmore Dryer will not heat

Does the limit switch have a reset button on it or is it an auto reset? Have you tried depressing the reset button on it if it is a manual reset? Have you checked your voltages to the gas valve, ignitor to make sure they are being called to come on? Trace your electrical connections from your electronics to these items. If they are not being told to come on, then you know it is the electronics. Also, have you checked the continuity of the door switch, and the ignite? These are all suggestions that must be ruled out before replacing parts.

hi..A poor connection between the wire terminals and the
heater relay causes high current draw and damages the
terminals on the heater relay on the main control board.

Maytag DG410 gas dryer-no flame, no heat. I replaced the ignitor - that apparently isn't the problem. Other ideas?


Motor runs, but main burner will not ignite
1.heat switch set wrong---correct switch setting
2.defective timer or timer circuit---check timer wiring--replace timer motor or switch as needed
3.defective centrifugal switch in motor---clean switch or replace as needed
4.gas supply valve closed----open gas valve
5.inoperative solenoid coil---test coil for open circuit & the voltage to it
???
Pilot burner goes out
1.insufficient gas supply---- low gas pressure or clogged pilot filter or partially closed gas valve
2.carbon deposit on thermocouple tube---clean tube & check pilot burner for proper combustion
3.improperly adjusted pilot flame--adjust pilot flame until faint yellow tip begins to appear
4.faulty ignition or reset valve or thermocouple---replace

Clothes not drying, but dryer runs & heats
1.defective operating thermostat---test thermostat, replace if defective
2.fan or it's pulley loose on shaft---tighten set screw
3.incorrect heat or timer settings---reset timer
4.clothes to wet when placed in dryer----wring out or extract water from clothes before placing in dryer
5.clogged lint screen or duct (little air motion)---clean out lint screen & duct

Dryer air is not getting hot. All other functions still work.


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

Have a Kenmore 796 gas drier that will not heat. Have tried all settings...hi, med, low, auto, manual. Cleaned out lint filter and duct. And yes the gas valve is open. Have no error codes and everything...


I assume it runs and this is from that stance. If it doesn't the motor has to be checked and the power coming in. In fact the dryer can run and still not have the correct power to opperate the heater.

A dryer has to have 2 things to dry clothes. 1 Air supply and exhaust, 2 Heating source. No mater if its a gas dryer or electric these 2 items are what dry the clothes..


A. If the dryer has all of these things it has to be heating and an air flow problem (kinked or dirty dryer duck, motor fan clogged with lint, vent flapper not opening...) is suspect.

B. ELECTRICAL
Assuming you have a volt meter and know how to use it properly.

These are the steps that the power and machine have to take to operate properly

1. power is correct (USA 220V across line and 115v to ground/neut) 2 hot lines with potential between them and a neutral and possible a ground
2 Door switch is closed
3 Timer switch closes and ready s power to heating element through centrifugal switch in the motor circuit after the motor is running.
4 the heating element is assumed to be good and have 220v at this point. Checking for voltage at the element will assure all before are ok and at least allowing the heater to work.
5 the heating element is controlled by 1 or more thermostats and a safety thermostat. If either of these switches do not close when the dryer is "cool" they are bad. NOTE some dryers could ahve 3 wire thermostats. These can read closed on one set and open on the other. And this is how they should be if good. But tracing the wire diagram will tell which set is closed and when.
6 if you have power, the timer contacts to the motor and the heater (separate circuits usually)are "closed", the motor runs, the cent switch "closes", the temperature operating thermostats are closed, and the heating element is good you have to have heat.

1 Check for 220V power into the dryer. If not check breakers and turn off and on several time pushing them firmly. If this is ok and 220V present step 1 is done. proceed through all steps above.

C Gas Dryers

The Gas dryer uses and has the same type controls up to the heating source.with 1 exception: The ignition circuit is only 115V and not 220V. Only 115 V (USA) is needed. If you plug in a ;lamp and it lites the power is fine.

All gas dryers made today use some type of electric ignition. The types of controls going into the heating unit are varied widely but include the following; 1 A gas valve to allow the gas to cycle on and off 2 A safety circuit that incorporates preignition safety, proving flame, safety cut off, and cycle operation. Some older types of dryers use a gas valve that has 2 steps for the valve to go through before ignition can occur. Usually these are noted as proving then operating. If flame is not present the gas valve will not open. If flame proves then goes out a lock out of the gas valve can occour on some gas heating source dryers..

The most common item and easiest to check maybe the ignitor. Usually a brite yellowish glow before ignition indicates all operating normally. If you dont see a glow in or around the gas heating area during start up the ignitor is suspect. check your wire diagram and connect your volt meter accordingly. If volts check ok the ignitor is most likely the trouble. If you can see it in pieces or remove it and note a whitish place on the surface particularly in 1 spot this is the open-burned out area. The ignitor is made of silicone carbide in some gas control systems and should be handled with care because they are easy to break.. Do not use any ignitor except the one recommended by . appliance parts people with good knowledge. Addaptation to these ignitors fitting in other that what they are made for is extremely dangerous and never condoned nor recommended even for a test. This is also known as "playing with fire".. .

If these instructions and explanations are foreign to you I recommend you contact a local service person to check the appliance for you. There are several reasons but mostly safety. DO NOT ASSUME THE POWER IS EVER OFF. Like an unloaded gun is the only one ever in an accident, same applies to electric. The only time anyone gets hurt by electric is when the power is off. If the plug isnt in your hands and you cant see the knives its assumed hot til checked. even with a breaker thrown still check it.

If this helped you in some way please send me a good report. Thank you for using fix ya.

Hi,
If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...
