Nobody except repairman who fixed our GE XL 44 gas oven seems to know this, but a GLOWING IGNITER does NOT always IGNITE GAS.... As they age, their bright, cheery glow is not up to flash point or something... My Frigidaire Gallery has had occasional "cold runs" yet occasionally lights; today took out old igniter, and it reads 69 ohms resistance, whereas the NEW replacement I just bought, remembering our expensive OVEN repairman measures 49 ohms. Less resistance (49 ohms) means MORE CURRENT, MORE WATTS, and MORE HEAT, which will IGNITE GAS....I don't know why so many people are replacing COILS, THERMOSTATS, etc. without checking resistance of OLD IGNITERS...

If ignitor not coming on could be flame sensor mounted on side of burner housing or ignitor ..if ignitor glowing but burner no lighting replace both solenoids bad connections interally on solenoids..also if ignitor not glowing possible small white thermal fuse open.. sensor and fuse can be jumped across to confirm ..

My whirlpool dryer comes on and runs good but it wont get hot can you tell me whats the problem


Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.




Enter your model number to see parts for your dryer.

Help me find my model number


Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.


Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.


Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

I have an Amana Designer Series Gas Dryer. It worked fine for more than 10 years. Suddenly, yesterday it still ran, but there was no heat. I opened the bottom panel while it was running, and...


Motor runs, but main burner will not ignite

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

I have an old Kenmore 70 Series dryer, just this weekend, the drum turns but no heat..... after a little search online, I suspect the pilot light went out. Where is the pilot light located? I lost the...


The burner is on the lower right side of the bottom under the drum. See this manual pdf page 23 for location and access. https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/4829abde74a34d7f85256ab000620794/$FILE/4322260.pdf

The burner uses an ignitor and a flame sensor vs a pilot light. See this link pages 12 - 14
https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/c5c81d2c8f26b1b5852574f20055c20c/$FILE/4314010.pdf Note the M series burner has been in use since 1984.

The dryer must have a complete termperature circuit and no "high temp limit" failures for the ignitor to light. That means the door is closed, motor is running, and the cycle thermostat is less than 135 deg F and the High limit thermostat is less than 180 deg F just to provide power to the gas valve solenoids, ignitor, and radiant / flame sensor.

Hi and welcome to FixYa. I am Kelly.

Your power for the burner assy goes on a series circuit from the timer to the high-limit thermostat to the operating thermostat to the thermal fuse to the gas burner assy, thru the motor centrifugal switch to the door switch. EACH of these must be functioning for the burner to light.

This manual will help with some of the how to do it as far as component access, removal and replacement of parts.

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.

I have a kirkland by whirlpool gas dryer that wont heat, any suggestions,all it seems to do is tumble


First, check the ignitor. If it is working properly it should glow noticeably. If the ignitor is working and the burner will not light, I would look at the gas valve coils. These small black electrical coils are right above the gas valves. These solenoids open the gas valves when energized. If faulty, the gas valves are not opened and the burner cannot light. Due to the difficulty in testing these solenoids, it is recommended that both (all) be replaced at once if any are suspected of being faulty. Hope this helped and best wishes.

Dryer will turn but won't heat.


Check the gas valve in the back of the unit and also check the Glow ignitor to make sure that you are igniting the gas to heat the drum. Sounds more like it is the Glow ignitor that is bad

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.

Kenmore gas dryer after 5 to 10 min. later no more heat


My Kenmore 80 series (model 11072802100) has the same problem that it fires up first and then stop producing heat after a few minutes. It's also 7 years old. After a while, if I restart it, it will run and do the same thing. I found a thread of discussion on another forum that says that this can be the gas valve coil (solenoids) problem as these coils turn on and off the gas flow to the chamber. I'm going to check out the coils, but don't know where they are located (can't find the manual). If anyone has any idea, please share. Or I'll just tear off the top and back to see where they are.

Any gurus here to help? Thanks.
