Gas dryer runs but no heat (electrical checks only)
On a gas dryer the electrical side of the burner can be diagnosed safely with gas and power off: thermal fuse, high-limit, cycling thermostat, igniter, flame (radiant) sensor and gas valve coils. Gas supply, gas lines, the valve body and gas pressure are off-limits: refer to a licensed gas technician.
