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

Dryer Repair
1

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

Hi, Check the thermostats for continuity. Unfortuneately the model number posted I can locate anywhere.
Can you please double check that.

Ok thanks, I’ll check them. Model number is Whirlpool SGDS800HQ0 (think i might have intially typed “5” vs. “S”). Whirlpool gas dryer with Costco/Kirkland badging.

Found that:
-Sensor continuity good, at ~0 ohms (still);
-Main thermostat, has 4 leads;

with ~0 ohms between two of them and
approx. 7k ohms between the 2nd set of leads.
-Backup thermostat at 0 ohms
Whether hot or cold, the resistances above do not seem to change.

Let me know that you think.

Thx.

did you check them with wires attached or detached?

6

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)…

I’d have to say the regulator is going out.

DRS,

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

Here are the break down diagrams for the Whirlpool dryer Model SGDS800HQ0

Gene & ibertyappl;

Are you guys talking about the same part; coils / regulator?

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!

Got the part, replaced coils and all works great now. Thanks Gene!!

You’re welcome. We’re glad you were able to fix it.

I have the same problem as DRS. Model #LG5801XKW0 Whirlpool
Where is the coil? Or what else could it be?

Thanks

Newguy,
Your coils are a little different that DRS’ but if you can pull up the breakdwon of your machine they are #32 on trhe burners page.

I have the same problem but when I loosened the limiter, part 15 ( Model SGDS800HQ0, ) the burner lit everytime. When it was tight it would fail to light. Anyone know what this brass screw/cap actually does? thanks

evanv,

Sounds like the problem with your dryer is a bad gas valve.
