It is not a   random failure   component;\n    most replacements should be paired with airflow correction, otherwise the replacement may open again.\n  <\/p>\n\n  <div class=\"h3\">3) Cycling thermostat out of tolerance (heat erratic or overheating)<\/div>\n  <p>\n    A thermostat that cycles incorrectly can cause unstable temperatures, long dry times, or frequent safety trips.\n    In troubleshooting, technicians separate thermostat failure from airflow restriction because airflow problems can mimic thermostat symptoms.\n  <\/p>\n\n  <div class=\"h3\">4) Heating element open (broken coil)<\/div>\n  <p>\n    A coil break creates an open circuit: the dryer runs but produces no heat. Element life is influenced by temperature cycling, oxidation, deformation, and hot spots  factors discussed in heater engineering literature.\n    TUTCO notes that all resistance heating elements eventually burn out and highlights how design choices (including watt density) and environment affect longevity.\n    <a href=\"https:\/\/tutco.com\/conductive\/heating-elements\" target=\"_blank\" rel=\"noopener nofollow\">\u30bd\u30fc\u30b9<\/a>.\n  <\/p>\n\n  <div class=\"h3\">5) Heating element short to housing (dangerous overheating pattern)<\/div>\n  <p>\n    If the coil sags or contacts metal, it can short and cause abnormal heating behavior. This can lead to overheating, repeated fuse\/thermostat failures, or electrical faults.\n  <\/p>\n\n  <div class=\"h3\">6) Power supply issue (missing leg on 240V circuit)<\/div>\n  <p>\n    Many electric dryers can still run the motor with a partial supply condition, while the heater cannot energize properly.\n    This is why   it turns on, so power must be fine   is a common diagnostic mistake.\n  <\/p>\n\n  <div class=\"h3\">7) Wiring\/terminal overheating or control relay issues<\/div>\n  <p>\n    Loose spade terminals can create localized heating due to increased resistance at the connection.\n    Discolored connectors, brittle insulation, or melted terminal blocks indicate the need for wiring repair  not only part replacement.\n  <\/p>\n\n  <div id=\"element-issues\" class=\"h2\">Heating element-specific issues (open, sag, hot spots, shorts)<\/div>\n  <div class=\"grid\">\n    <div class=\"box\">\n      <div class=\"h3\">Issue A: Open coil (no continuity)<\/div>\n      <p>\n        Most common direct element failure.

Whirlpool  s water heater guidance explicitly says to verify voltage and wattage on the data plate before installing a new element.\n      That same discipline applies to appliance heaters: correct rating reduces overheating risk and improves reliability.\n      <a href=\"https:\/\/www.whirlpoolwaterheaters.com\/support\/help\/element-was-out-of-range\/24\" target=\"_blank\" rel=\"noopener nofollow\">\u53c2\u8003<\/a>.\n    <\/p>\n  <\/div>\n\n  <div id=\"airflow\" class=\"h2\">Airflow and venting: the hidden driver of repeat burnouts<\/div>\n  <p>\n    Airflow is the   cooling system   of a dryer heater. When airflow drops, element temperature rises, oxidation accelerates, and safety devices open more often.\n    In heater engineering terms, this is a shift in operating conditions that pushes the element outside its intended thermal window.\n  <\/p>\n\n  <div class=\"chart\" aria-label=\"chart-airflow-effects\">\n    <div class=\"h4\">Chart 2    What airflow problems do to a Duet dryer (cause    effect)<\/div>\n    <div class=\"barRow\">\n      <div class=\"barLabel\">Low airflow    high heater temp<\/div>\n      <div class=\"barTrack\"><div class=\"barFill\" style=\"width:86%;background:#ef4444\"><\/div><\/div>\n      <div class=\"barVal\">Very likely<\/div>\n    <\/div>\n    <div class=\"barRow\">\n      <div class=\"barLabel\">High temp    thermal fuse opens<\/div>\n      <div class=\"barTrack\"><div class=\"barFill\" style=\"width:72%;background:#f97316\"><\/div><\/div>\n      <div class=\"barVal\">Likely<\/div>\n    <\/div>\n    <div class=\"barRow\">\n      <div class=\"barLabel\">High temp    coil sag\/short risk<\/div>\n      <div class=\"barTrack\"><div class=\"barFill\" style=\"width:64%;background:#f59e0b\"><\/div><\/div>\n      <div class=\"barVal\">Likely<\/div>\n    <\/div>\n    <div class=\"barRow\">\n      <div class=\"barLabel\">Long dry time complaints<\/div>\n      <div class=\"barTrack\"><div class=\"barFill\" style=\"width:78%;background:#3b82f6\"><\/div><\/div>\n      <div class=\"barVal\">Very likely<\/div>\n    <\/div>\n    <p class=\"caption\">A service reasoning chart: restricted venting explains both   no heat   and   takes forever   patterns, and it is the leading reason new elements fail again.<\/p>\n  <\/div>\n\n  <div id=\"parts\" class=\"h2\">Selecting the correct replacement part (rating + fit + quality)<\/div>\n  <div class=\"box\">\n    <div class=\"h3\">Avoid the   looks similar   purchase trap<\/div>\n    <p>\n      Heating elements are engineered assemblies.

Low airflow increases heater temperature and accelerates burnout and safety trips.\n    <\/p>\n  <\/div>\n\n  <div class=\"box\">\n    <div class=\"h3\">3) Should the thermal fuse be replaced with the heating element?<\/div>\n    <p>\n      Only if testing confirms the fuse is open.
