Dryer no heat

My gas dryer glows for 10 -15 seconds then it clicks and does not ignite.
It tries again in another minute. I can smell gas so I turn it off.
I replaced the coils and it does the same thing. Could it be the gas valve and I could I check the valve. There is no lint build up any where.
Thanks

I would check the thermal fuse first.

I checked the thermal fuse. What would be the next step? Could the gas valve bot be opening properly?

Ok I replaced coils, ignitor is good ( 80 ohms) the flame sensor good. Dryer glows but no ignition. Any ideas? Thank you
ps looked at new dryers…ouch would like to repair old one.

even though the ignitor checks good, it can still be bad. i have found that ignitors will read good until they begin to draw amperage. an ignitor can have a small crack in it and still glow. the ignitor must draw at least three amps to activate the coils to open the gas valve. one of the coils is a holding coil. did you replace both coils?

Yes I replaced both coils. I am going to replace the ignitor. I was told that when they get into the 90 ohm reading to replace. I can smell gas so I don’t think it’s the valve. Thank you Scott5495 appreciate the reply it reinforces decision.
