Soot in gas dryer

Normally soot is from a range that hasn't been converted for the gas type, like natural or propane. It may be set up for natural when you're on propane or visa versa. Has this range ever worked properly without sooting?

I too have the same problem with my Admiral dryer. Have come to the conclusion that the soot is making all my clothes greyer, but just noticed it with my whites. Took apart my dryer today and first of all found that the outlet below the lint vent was plugged. There is no soot on the outside of the drum or the dryer housing...however there is soot within the metal tube that surrounds the gas burner. Seems the gas is not being burned properly or the plugged lint trap was not letting the burned gases escape??? Laura

Your range needs servicing.
The burners need to be cleaned and the air shutters adjusted.

the soot is coming from the flame at the gas heater box the drier needs to be converted to propane the flame is too large without the conversion kit installed and thus creates soot at the vent. contact a local repair place for this one it can be tricky.

burners burning yellow , in complete combustion , blocked air ways to burner , it needs a service soon as poss

have you recently changed from natural gas to liquid propane, or visversa? if so, this could be the problem. especially natural gas to lp.

You'll have to contact Frigidaire to see if a conversion kit is available. Normally, it's just an orifice replaced on the gas valve.

There are several possible causes: a)  exhaust vent is restricted forcing the lint to enter the dryer shell and overheat and/or be picked up by the blower -- you seem to have inspected this b)  check the hot gas inlet to the drum.. on some dryers, lint buildup can occur in tight spots and it will overheat and char c)  ducting is not intact or leaks allowing lint to leak into the dryer shell -- this will occur over time, and all dryers should be taken apart and cleaned out on a regular basis... also, all ducting should be inspected and sealed as needed d)  verify that the inlet vents to the dryer shell are not blocked and allow adequate air flow to the burner assembly -- natural gas normally won't smoke due to incomplete combustion, but..  likewise, verify the room has adequate ventilation particularly if the utility room or closet is very small,  e)  check the drum drive belt, as it gets old, it will release dust and minute pieces which will be picked up by the blower -- replace if needed... f)  verify that the seals on the drum are still good -- replace as needed g)  as 'washer-tech' advised, do a thorough cleaning and inspection... put it back together with all ducting tight and free flowing

sounds like you migt have had a flash fire in the vent line. you need to open the dryer and clean out the vent line
