My gas dryer runs fine for one load but then in follow up loads gas flame will not ignite. Vent is all cleaned out. I have replaced coil and thermal fuse. Still not working.

Hi,

Did you also clean out around the blower housing?
If so then you may have a week ignitor.

blower housing appears to be clean. should I replace igniter?

OK- I have replaced the igniter with same results. It fires up on first load but after that coil lights up but no flame. If I let it cool down for 20 minutes it will fire up again. What do I replace now??!!! FLame sensor?

Hi.

Tell me, please , if the ignitor glows and shots off? If it does then most likely you need to replace the safety gas valve (comes with new set of coils). When replacing it don't forget to turn the gas off.

The safety gas valve Part number: AP3081145

Hi.

To remove the gas valve :

- Turn the gas off.
- disconnect the gas line from the dryer.
- remove the back panel.
- take the bracket off the end gas pipe.
- remove screws holding the burner to the bottom.
- pull out the assembly. Note - be very careful not to brake the ignitor.
- remove two screws holding valve to the bracket.
- install orifice from old valve to the new one if needed.
- reinstall everything .

I hope this will help you.

Thank you. Post the results.

Simon.

So I replaced the gas valve. The igniter glows and the flame burns but not for the whole cycle. I am thinking it is the flame sensor- any thoughts??

Hi.

The gas flame is not suppose to stay on all the time the dryer is on. It cycles on and off. 2-3 min. on then 1min. off.

Thank you.

It burns for a part of the cycle then stops. It never reignites leaving a load of laundry still damp.
