Dryer shows F30 and may not heat or may shut off quickly

Safety First: Unplug the dryer and shut off gas before disconnecting venting.

Steps:

• Inspect vent hose: Pull the dryer away from the wall. Check the vent hose for kinks, crushing, or disconnections. Replace with a rigid or semi-rigid metal duct if using plastic or foil.
• Clean vent system: Disconnect the vent from the dryer and from the wall. Use a vent brush or vacuum to remove lint from the entire run to the outside hood.
• Check exterior hood: Ensure the outside vent hood opens freely and is not blocked by lint, nests, or debris.
• Test airflow: Run the dryer (no load) with the vent disconnected. Strong airflow at the outlet indicates internal blower is working. Weak airflow suggests a blower wheel issue or internal blockage.
• Inspect blower wheel: Access the blower housing, check that the blower wheel is firmly attached to the motor shaft and not packed with lint. Replace if cracked or loose.
