WGD8200yw whl dryer flame goes out quick
« on: October 22, 2014, 07:12:44 PM »
So today I had this whirlpool dryer, it has 2 belts and a control board...so not the most simple unit. It had a f4 e3 code (i think) which is air flow restriction...so the first thing I notice is the flame isnt staying on very long...i figure I'll just take it apart and remove all of the lint...I removed a ton of lint from this thing...


Now that is is clean I put it back together and run it.  Same flame problem- the flame comes on for maybe 10 seconds and cuts out...then about a minute later it does the same thing. It will do this for the whole timed dry cycle...My first thought is "ok, coils are good, everything in series with the burner is good(flame sensor, operating tstat, hi limit tstat)...must be the thermistor on the blower housing?  I replace the thermistor, which I didn't test, couldn't get ahold of techline(on hold almost 20 minutes before I hung up) to see what it should ohm out at. So I replaced this thermistor, and boom...same problem...

So what would cause the dryer to keep cycling the flame, but it to go out well before the dryer reaches operating temperature? Can the coils be weak? and still open the valves every few minutes, but be bad?

thanks in advance

I cleaned the vent, and blower housing.  Ran the unit unattached to the vent after cleaning with the same results.  Flame goes out with good airflow

I would suspect a faulty flame sensor or hi limit short cycling

Possibly the Coils are failing when power is supplied and they get warm.

So I got this fixed today...weird problem....at least for a newbie like myself. As the flame burned, the tip of part of the flame was hitting the operating thermostat on the burner tube...I thought it didn't seem right so I turned the thermostat sideways away from the hole in the burner and sure enough the dryer ran great...

So I rotated the burner tube clockwise about 20 degrees and redrilled the screw holes, and voila! I'm not sure how acceptable this fix is, but for some reason the tip of the flame was hitting it perfect...My thought now is that they had a drop in gas pressure? there was no shutter on the burner. I also cleared the oriface hole...

Gas pressure or air flow causing flame not to be directed properly. This can be many many things
