Airflow Gas Dryers; Airflow Problems - GE DSXH47EG Technical Service Manual

The air passes through the drum, picking up moisture
and is drawn through the lint filter into the ductwork at
the front of the dryer.
The air enters the fan housing and is pushed out
the exhaust vent to the outside of the house.

Airflow gas dryers:

The airflow in gas dryers is similar to electric dryers except
for the heat source and the rear of the drum. The air
enters the cavity through the louvered opening in the
right rear corner of the dryer. The air is then pulled across
the gas burner through the burner chamber and ducted
to the rear of the drum.
The drum is the same as in the electric dryer, except it
does not have a heat baffle on it.

Airflow problems:

Airflow problems are usually caused by restrictions,
leaks or short unrestricted vents resulting in longer
drying times, hotter dryer surfaces and, in extreme cases,
the thermal limiter may open on electric dryers.
