Gas dryers stop heating for several reasons. Use these steps to troubleshoot your dryer and identify the root of the problem. The required supplies are an ohmmeter, a handheld vacuum and a small flashlight. A screwdriver is also helpful for many dryer models.Continue Reading
Confirm that your dryer has adequate power. Check its plugs, cables and the amount of voltage coming through the outlet. Gas dryers need 110 volts or more.
Pull the dryer away from the wall so you have access to its back panel.
Remove the back panel and locate the thermal fuse. In most dryers the fuse sits near or on the exhaust duct. Use a flashlight to help you find it. Remove the fuse and connect it to an ohmmeter. Unless the display reads "O," install a new fuse.
Perform continuity tests on the gas coils and lighter. If either part is defective, replace it.
Safe, effective dryer operation depends on unobstructed airflow. Inspect the vents and ducts for lint blockage and use a hand vacuum to remove debris. Pass the vacuum over the lint trap also.
Broken or dislodged thermostats cause many problems. If the thermostat isn't in the blower housing or beneath the lint trap, install a new one in either location.
