Had a warranty service call bc my fairly brand-new dryer stopped working on timed dry (it gets hot and exhaust works but I have no idea why it is not drying) they took a quick look and said they could find. I problem. Itís a gas model. Itís seems to dry okay on sensor setting. I need some ideas as to whatís wrong to communicate to service tech and also for my own sanity.

Dryer Problem ?

Hi Mike, exactly what happens when you put in a good sized normal load and set the timed dry to 60 minutes ?

Your post makes little sense, what did the service tech say ?

Thanks John.

Thatís my prob, my post doesnít make much sense to me either nor anyone I explain it to. So the tech just checked to see if the dryer was firing and hat he sensor was working.. Which it all is.

Iím guessing it might be something computer related. If I put in a load on 60 min the cycle ends with warm wet clothes. It has been taking 3 60 mi Ute cycles to dry. The exhaust works and duct is totally clear of obstructions.

Hi Mike, This problem should be easy to figure out if you give me more information.

 

How long would the same load take to dry on the sensor setting that you said takes 3 60 minute cycles on timed dry? 

 

Take the lower panel off and watch the burner operation, If you put a 10 # or larger load of heavy cotton towels etc and set the dryer for 60 minutes the burner should not cycle off once in less than 30 minutes and probably longer.

 

If it does cycle off much sooner especially in less than 15 minutes, disconnect the vent from the back of the dryer and see if the burner runs any longer.

 

Did this dryer work fine on timed dry and suddenly stop correctly on timed dry ?

^That is correct.

That's very odd.† The only effective difference between timed dry and sensor dry, of course, is that timed dry runs for the selected number of minutes vs. sensor dry "time" controlled according to the sensor readings and programmed algorithms.† The rest of the machine, unless there's something different about SQ, operates identically ... drum rotation, airflow, heating source, temperature control.

Assuming that any given load does dry fully when run on a sensor cycle, how long does it take to finish?

same issue

I had the same issue.Called gas company and they replaced the coils. no help. Called a local reputable service tech and they said vent pipe was to long. Helped but not happy as vented under home. This is SQ gas dryer. I hate how the coils come on and off on and off so frequently. Seems to be a normal thing as it drys fine now.

Sounds like there is an air leak. The air flow in/out of the drum has been disrupted.

Methane or propane?

Are you using natural gas or propane?

If your gas is bottled gas / liquified propane/ propane, it is important to be sure the machine's burner has been properly converted for such gas.

A natural gas dryer using propane has a HUGE flame and the burner will cycle on and off VERY rapidly. Carbon buildup and yellow/orange LIGHT will come out of the machine.

Obviously, also a fire hazard to run a gas dryer with the "wrong" gas getting to the burner /orifice/regulator.

Perhaps this accounts for the whacky drying....

Good luck!

I've never heard of a gas dryer with coils.

 

Both of these SQ dryers sound like rogue mutants based on the descriptions provided.

Coil is alternate terminology for solenoid.
