Whirlpool Gas Dryer Runs, Start Heating then gas heat goes off - stays off...

Gas dryer starts/runs ok AT START… but heating stops after about 5-10min (with tumbler/blower still going). To be clear, sequence is:

  • dryer starts/runs AS NORMAL for a minute or so…
  • then i can see glow/igniter start…
  • gas flame lights & runs as normal for ~5-10min…
    > but then stops & does not relight (although I’ve seen glow/igniter heat up)
  • dryer continued tumbling on with cool air.

:frowning:

Other info:

  • if allowed to cool down for say 5min, will restart above sequence

  • if a quick 1min stop/restart tried, there is no gas re-lighting (although glow/igniter goes on for a few seconds)

  • I suspect the sensor (on heater section), yes/no? It measure less than 1ohm accross whether hot OR cold.

  • i have not tested/measured other thermostats…

Thx.

DRS
Can see the glow/igniter

did you check them with wires attached or detached?

It was a detached measurement…

Add’l. info: Also, when dryer unning, no voltage DROP accross any of the (three) sensors/thermostats… (measures 117vac at each terminal)…

DRS,

According to your description, most likely the problem with your dryer is a bad gas valve coils.

  • The part number for the kit of coils is AP3094251

The coils are on top of the regulator. You can see them on the break down of your dryer.
Hope that helps.
Gene was more help than I was. Glad he jumped in!

I have the same problem but when I loosened the limiter, part 15 ( http://www.appliancepartspros.com/partsearch/model.aspx?diagram_id=45079&&model_id=246875, ) the burner lit everytime. When it was tight it would fail to light. Anyone know what this brass screw/cap actually does? thanks

Replace the stand pipe with the gasket. Check the water level. Make sure there are no suds.

Kathy,
I found a simple solution to your problem. I worked for me. Remove the float assembly (top Portion). It comes out very easily. Take a short piece of tubing (from any lowes or home depot) that will slip over the plunger of the float after the tubing is split down the middle. This tubing has to be split to fit over the bottom of the plunger and still be small enough to allow the slide to go up and down on the holder that is part of the assembly that is attached to the bottom of the inside of the DW tub. You will need to only use a length of the tubing that is long enough to ride inside of the assembly.

Hope it helps. It stopped my leak.

You may also want to check:

  1. That the dishwasher is level or slightly tilted to the back.
  2. That the wash arm holes are clear. Sometimes they can get a partial plug and it will spray water out at a weird angle and cause a leak. I find it best to remove junk from the holes when it is wet using a pair of tweezers.
