Dryer heats up the first time. Then won’t light after that. I’ve replaced the igniter, the gas coils, the flame sensor and the high limit thermostat. If the dryer sits for awhile, 5-10 minutes, the dryer will light again. The igniter glows, but doesn’t light up.
Cause 1 Thermal Fuse The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or at the dryer’s heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity meaning the electrical path is broken and the fuse has blown out. A multimeter can be used to test it for continuity. Be aware that a blown thermal fuse is an indication of a restricted exhaust vent from the dryer to the outside. Always check the dryer venting when replacing a blown thermal fuse. Cause 2 Gas Valve Solenoid Gas dryers have two or more gas valve solenoid coils. The gas valve solenoids open the gas valve ports to allow gas to flow into the burner assembly. If a gas valve solenoid fails, the dryer won’t heat. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out but does not ignite the gas, the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend that you replace them as a set. Cause 3 Igniter The igniter uses heat to ignite the gas in the burner assembly. If the igniter is not working, the gas will not ignite, preventing the dryer from heating. To determine if the igniter has burned out, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.
Phil, just a shot in the dark, check that the vent is clear/free of lint, debris,etc and open with no damage or kinks. I hope this helped you out, if so let me know by pressing the helpful button.
My Maytag gas dryer heats up one day and not the next day. I always clean the lint trap after each load. I have also checked vent going out the house. Cleaned floor and have the dryer pulled out more from the wall so that there is no kink in the vent hose. I am going crazy that one day it heats and the next day it doesnt heat.
