A dryer can tumble even if the heater circuit is open (failed element, blown thermal fuse, open thermostat, or power supply issue affecting the heater).\n    <\/p>\n  <\/div>\n\n  <div class=\"box\">\n    <div class=\"t3\">2) Is continuity enough to prove the element is good?<\/div>\n    <p>\n      No. Continuity only shows the coil is not broken. A professional test also checks for a short to the housing (ground fault) and verifies the safety chain.\n    <\/p>\n  <\/div>\n\n  <div class=\"box\">\n    <div class=\"t3\">3) What causes thermal fuses to blow?<\/div>\n    <p>\n      Most commonly overheating due to restricted airflow  lint buildup, crushed venting, blocked exterior termination, or a failing blower path.\n    <\/p>\n  <\/div>\n\n  <div class=\"box\">\n    <div class=\"t3\">4) Why do new heating elements fail quickly?<\/div>\n    <p>\n      The most common reasons are unresolved airflow restriction, coil rubbing\/shorting due to misalignment, or heat-damaged terminals creating high-resistance hot spots.\n    <\/p>\n  <\/div>\n\n  <div class=\"box\">\n    <div class=\"t3\">5) What is   resistive (Joule) heating  ?<\/div>\n    <p>\n      It is the conversion of electrical energy into heat when current flows through a resistive alloy.
