The Flame Sensor is an OEM replacement part for Whirlpool gas dryers. This component plays a critical safety role by monitoring the presence of the gas burner flame during the drying cycle.

Symptoms that may indicate a faulty flame sensor include:

  • The dryer not heating or producing heat properly
  • Error codes related to the gas system or ignition failure
  • The dryer shutting off unexpectedly during cycles

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore gas dryer models.

Questions & Answers

For Whirlpool Flame Sensor (Part Number: OEM18024891)

Alex for Model Number LGR8648LW0

Dryer heats up for about 4 minutes then continues tumbling without heating up. When it is stopped for 15 or so minutes, it will fire up again. Vent is clear. Once the flames go out, it glows for a few seconds at least once a minute, but does not re-fire. I replaced the coils about a year ago, can they have gone bad? Is it consistent with my problem if the timer works on a timed dry, but does not rotate once it's set in the Auto dry? Even if the clothes are dry? When the dryer first showed signs of a problem it was re-firing up, but less often then it should so clothes were taking longer to dry, once in a while we'd smell a little gas (vents in to basement)but not getting that now The last problem (last year) when coils went, the dryer was periodically making a clicking sound, now that isn't present

Hello Alex. It sounds like the coils are bad and will need to be replaced. You will need to check your vent first and make sure it is not kinked or clogged. Hope this helps.

It will help absolutely, if it resolves my issue! :)! 1) I am just wondering what made this different then when it was the coils? 2) Also although I didn't physically go behind the dryer yet, the flow comes out pretty good from the diverter, is that good enough to rule out a different cause? 3) Finally, is there a different part that could cause similar/same 'symptoms', based on my description? I just want to rule out any other possibilities, need the dryer up and running!

1 Answer

Hello Lisa. Lets try this, unhook the vent from the dryer and try running a load and see what it does. If it works properly, then the vent is the issue. If there is still a problem, test the cycling thermostat. It should read closed on the large terminals and read resistance on the small terminals. If it is good, check the high limit thermostat W11050897 and see if it is bad. If it opens up, the dryer will not heat again until it closes. The coils should be ok since you replaced them already. Hope this helps.

Lisa for Model Number LGR8648LW0

Dryer heats up or 5-10 minutes, then (because I have a diverter on the dryer vent to help warm the basement) I smell gas for a moment, and the air comes out cool. Five minutes later, heat comes back, and so it continues. Dryer will run all night drying a load, odd thing is the timer works, will count down, will cool and stay cooling, but when I have set to detect dryness, even when the clothes eventually dry, it stays at setting. Also, I replaced the coils 8 months ago (never smelled gas, and heated up once or twice and stayed cool, there was also clicking that I don't hear this time.

Hello Lisa. It sounds like the cycling thermostat WP3387134 may be bad. This is what turns the heat on and off based on the heat inside the dryer. Make sure the venting system is clear from cloggs and kinks. Hope this helps.

Hello Jeff. It sounds like the coils 279834 are bad. They can test good, but when you put them under a load, they will open up. The flame sensor is testing ok. Hope this helps.
