I am 99% sure it is electronic ignition. There a dryers that had pilots but those are very old. So what you can do is start with the basics. Make sure the gas valve for the dryer is on and there is gas pressure coming from the connector. Make sure there is no debris blocking gas flow in the gas line. If the dryer has a removable door or burner inspection hole on the bottom pull it loose with a screw driver otherwise you will need to remove the back cover of the dryer. Turn on the dryer and watch for the hot surface igniter to come on. It will glow very bright then you should hear the gas solenoid valve click and the burner should come on. If the solenoid opens and the igniter does not come on inspect the burner orfice for any blockage. If the igniter does not come on then you will need to test the igniter for the proper ohm reading with a fluke meter. You will need to verify the igniter is getting power. If the igniter tests good it might be a bad solenoid valve(there are two) or a grounding issue.

Burner lights and goes out


It may may be the safety system for pilot light is maladjusted. There is a sensor which has to be heated by the pilot light or the valve shuts down altogether. If the pilot light stays lit then you check to see if it is positioned to light main burner.

Dryer runs but does not heat on maytag model med6000xw1


If you have a newer model with electronic ignition, check igniter by the burner, or if a pilot light ignition, obviously re-light, but possibly the gas safety interlock switch is tripped by a weak pilot flame, which causes main gas valve to stay off. Best guess, igniter element has cracked, and is simple to replace, order online.

Hi.. I have a Whirlpool dryer Model LG5801XM Serial # M41503253. The temperature control switch broke (spindle that attaches to the knob). I ordered a new switch but the configuration is different. ...


In many models manufacturers redesign switches over time and they normally work just fine. Occassionally this is not the case. Take both switches to a parts supplier and explain what the new switch is doing. They will most likely tell you the redesigned switch is not compatible with your model dryer and order you the correct switch. Obviously you don't want to use the dryer with the smell of gas in the area. If you Have a pilot light and not an electrical ignitor make sure the pilot light is lit as it would have gone out when the switch was removed as a safety feature.

Have a Whirlpool Gas Dryer - model # lgr7646a spins but no heat


Thre is no pilot light. This dryer uses an ignitor (glow bar or coil).
Open the lower front "door" (small access door) and turn on dryer.
If the ignitor does not glow (bright orange), then the ignitor needs to be replaced ($60).
If it does glow, then the gas valve needs replacement ($60).
If it isd the valve, the internal spring is stuck. Do not try to repair it, you must replace it.

Heat goes off after a min. in use. Whirlpool Model # LGR4634JQ2. Took apart back and cleaned exhaust.


if it's gas it could be that the pilot is not close enough to the gas sensor and when the drier is in motion the extra air motion shuts it off.
if its elect it could be that one of the fuses are not set shut both fuses down and turn them BOTH back on
Gas clean the elect pilot and be sure it is close to the sensor that looks like a little tube

No heat in gas dryer


Remove the front panel. Leave the door switch wires connected.
Turn the dryer on and look for the glow bar ignitor to glow red.
This may take a couple minutes.
No glow. Replace the ignitor.

Whirlpool Gas Dryer


Pilot Light? Are you sure? All the gas dryers I've ever worked on were pilot-less. There should be a glow-type igniter that heats up when the dryer is turned on. When it reaches a certain current potential a gas valve is opened and the burner ignites. How old is this dryer? Maybe this is something I've never seen before. Is the dryer working at all? If not, here's a way you can narrow down the possibilities of problems:


You need to gain access to view the inside of the dryer, first. With the dryer plugged in, push the start button. If you hear a "click" and the igniter still does not come on, you probably have a bad igniter. If you don't hear a "click", the radiant heat senor is probably bad causing the igniter not to glow. You have to listen very carefully for the clicking noise, though. It's not very distinct with some dryers. Now, the igniter can glow sometimes and still be bad. The way your dryer works; it looks for a certain current potential (roughly 2.7 to 3.2 amps depending on type of igniter) on the igniter before the gas valve opens to ignite. If the igniter is weak, the gas valve may not open. This is a safety feature that prevents gas from leaking into your home. I hope this may help you. Let me know if I can assist further.
