Whirlpool gas dryer model WGD5860SW0, no heat, igniter not glowing and no flame.

Check to see if there is a glow at the burner when you start it up. If it glows then the igniter is good. If not it could be a thermal fuse, bad igniter, flame sensor or a bad cycling thermostat. If it glows then it could be the gas valve coils.

You are on track that is you're issue and the solenoids should be replaced, you seem to be very able but if a video is needed I can send one. Thanks and Good Luck!!!!!!

Sounds more like a Thermal Fuse or High limit thermostat.
If they are good...the Dryer Igniter or Gas Valve solenoid may be a problem. Flame sensors are not usually a 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.

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

Hello there and welcome to fixya

Here are the most common things that will need to be checked with a meter to ensure there is continuity on these parts no continuity means that the part is bad and needs replacement ok?

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.

What solenoids are you referring to?

When you set the timer and heat selector switches on your dryer and press the button [switch] to turn it on, the direction of 120VAC passes through the heat selector switch through the timer switch through the cycling thermostat through the hi-limit switch, through the thermal cut-off fuse to the burner assembly's gas valve.

Simultaneously, as the current is traveling through a path to the 1st gas valve coil, current is also traveling through a path to the flame sensor- and then to the igniter.

The igniter will begin to glow and when it gets hot enough, the flame sensor will detect the heat and switch off. which then diverts current to the second gas valve coils.

The second gas valve coils activate plungers in the gas valve which allows gas to flow out into the burner housing. The igniter still being hot, ignites the gas to a long blue flame.

To maintain the proper air temperature, the heat in the blower housing is monitored by the cycling thermostat. During normal operation, air temperature should be between 120 degrees Fahrenheit and 160 degrees Fahrenheit.

When the air reaches the proper temperature specific to your dryer model, the cycling thermostat will switch off the voltage to the burner assembly.

The hi-limit thermostat and thermal cut-off fuse monitor the drum air temperature. If there is an air flow problem [restriction or total blockage], the hi-limit thermostat may switch off the voltage to prevent damage to the dryer.

Eventually, if the air flow problem [restriction or total blockage] is not corrected, the thermal cut-off fuse will fail (blow) and the dryer won't heat at all.

Check continuity to the following components, thermal cut-off fuse, hi-limit thermostat, igniter, flame sensor, and cycling thermostat. Of course you will take your readings with the power cord of the dryer unplugged from the wall outlet.

You will either disconnect [isolate] any of the wire leads going to their respective components during the test [using a multimeter (analog or digital)]; OR remove each of the components entirely from the dryer to test them.

1.) A good thermal cut-off fuse will have 0 Ohms of resistance. On the other hand, if the needle [on a an analog tester] does not move OR the digital display [on a digital meter] has not changed significantly, there is NO continuity - which means the fuse has burned out and needs to be replaced

2.) A dryer's Hi-Limit Thermostat is activated by hi-temperature changes (between 250 degrees Fahrenheit and 300 degrees Fahrenheit.

A good hi-limit thermostat will have 0 Ohms of resistance at room temperature.

To test the thermostat's response to temperature change, place the component on an electric griddle or skillet. Set the heat on the skillet or griddle to the appropriate temperature according to the temperature rating stamped on the hi-limit thermostat you are testing. If the hi-limit thermostat switches off within 5% of that temperature, the part is functioning properly. However, if the hi-limit thermostat does not switch off OR switches off prematurely, the hi-limit thermostat is faulty and will have to be replaced. [Remember, when the switch turns off at the appropriate temperature level- you should get a high resistance reading to show that the circuit is "open")

3.) Perform the same procedure as step 2 to test the Cycling Thermostat: First at room temperature and then its response to temperature change. The only difference is, the test temperature range will be somewhere between 120-160 degrees Fahrenheit Once again, refer to the temperature rating stamped on the component you are testing- and the 5% tolerance remains the same, too.

4.) The resistance reading for the igniter is between 50 and 400 Ohms of resistance; anything else, it's faulty- toss it and replace it.

5.) You should get a resistance reading of 0 Ohms at the flame sensor-

Flame sensors are tricky though. Flame sensors could still short out and allow the igniter to glow- but would prevent voltage from reaching the gas coil. For example, the igniter will glow and not turn off and a flame will not be established because there was no voltage at the gas coil to open up and release gas for ignition.

Hope this info helps...I would appreciate a follow-up from you when you resolve this problem- to gain more knowledge and skill.

Thank-you and best wishes on your project

Hi.

If dryer is electric check for lint obstructions, check ventilation, test thermal fuse, thermistor, cycling thermostat and high limit, element and fan.

If dryer is gas check for lint obstructions, check ventilation, test thermal fuse, thermistor, cycling thermostat and high limit, igniter, coils, burner, flame sensor and fan.

There are quite a few things to check on a gas dryer.

1. Gas valve coils
2. Igniter
3. Flame Sensor
4. Thermal Fuse
5. High Limit Thermostat
6. Cycling Thermostat

Here is a video to walk you thru the process of doing the diagnostics on the dryer to find the failed component.

Things that could stop a gas dryer from heating:
- glow bar igniter, thermal fuse , coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.
Problem -
Gas flame comes on first few times then quits and igniter keeps cycling on and off but never lets the gas go.
Answer ( most common ) -
Replace the coils on the Gas Valve.

Problem -
No flame, no igniter glowing at all,
Answer ( most common ) -
Inspect igniter for small burnt spot on dark gray or black part of igniter or check for 110 volts to igniter when dryer should be calling for heat.
