Dryer thermal fuse replacement: causes of blown fuses, error codes, quick checks, and when to call professional dryer repair.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Why do we use it?

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Where does it come from?‍

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

Dryer won’t heat or won’t start? A blown thermal fuse is a common cause. Learn the symptoms, airflow‑related causes, related error codes, safe quick fixes, and when professional replacement is required.

A dryer that suddenly stops heating or will not turn on at all may have a blown thermal fuse. This small, one‑time safety device protects the dryer from overheating by cutting power to the heating element or entire machine when temperatures exceed safe limits. Once it trips, the fuse cannot be reset and must be replaced. Thermal fuses typically fail due to blocked vents, lint buildup, or airflow restrictions. Because they are non‑resettable, understanding symptoms and diagnosing why it blew are just as important as the replacement itself. Replacing the fuse restores operation, but the underlying cause—restricted airflow, failed cycling thermostat, or clogged duct—must be corrected to prevent repeat failures. Knowing how to identify, access, and replace the fuse ensures safe dryer function and prevents fire hazards.

Landlord responsibility: In New York, landlords are legally obligated to maintain appliances they provide in a safe and working order. This is part of the "Warranty of Habitability".

Symptoms of a blown thermal fuse include a dryer that powers on but produces no heat, or in some models, a dryer that will not start at all. Electric dryers may tumble with no heat, while gas dryers may run without igniting. Some units appear completely dead if the fuse is wired in series with line power. Another clue is a dryer that shut off mid‑cycle and never restarted. Attempting multiple cycles yields the same cold or dead result. If airflow is blocked, you may notice excessive heat on the cabinet or a burning smell before the fuse blows. Unlike thermostats, thermal fuses cannot reset once tripped—repeated cold operation is a hallmark. Technicians often confirm by testing continuity with a multimeter across the fuse. No continuity = blown fuse. Error codes may appear depending on brand, often pointing to overheating, airflow restriction, or safety shutdown.

Qiuck Fixes

Quick checks before replacement include inspecting and cleaning the lint filter, vent duct, and blower housing. Disconnect power and verify the vent path is clear to outside. Measure continuity across the fuse with a multimeter—if open, it must be replaced. Access panels usually expose the fuse near the blower housing or heater assembly. Remove screws, swap the fuse with an OEM replacement, and reassemble. Always correct airflow issues first—straighten ducts, shorten runs, and clean vent hoods. If thermostats or cycling controls are faulty, replace them together with the fuse. Do not bypass the fuse, as it is a critical fire safety device. After replacement, run the dryer empty on high heat to confirm normal heating and airflow before resuming laundry loads.

Error Codes

Error codes tied to thermal fuse failure vary. Whirlpool/Maytag often show F31/F32 for motor issues that arise if the fuse opens the circuit. Some Samsung/LG units trigger HE, tS, or TE codes when heating circuits do not energize. Frigidaire/Electrolux can display E64/E68 for heating element faults caused by open fuses. GE may show E61/E62 for heater relay faults. Bosch models sometimes stop with generic heating error codes or no code at all, leaving only cold operation. Certain dryers simply go dead with no display, which indirectly indicates the fuse has blown. Although codes differ, their root meaning is the same: the heating or motor circuit was interrupted by an open safety device, usually the thermal fuse.

When to Call a Professional

Call a professional if the dryer remains dead after fuse replacement, or if the fuse blows repeatedly within days. Persistent failures suggest hidden blockages, failed thermostats, or motor/blower issues that require deeper diagnostics. If error codes like HE, E64, or F31 accompany symptoms, advanced testing of circuits, relays, and sensors is necessary. Professionals can measure vent airflow with anemometers, test cycling thermostats under load, inspect blower wheels, and replace motor assemblies if overheating persists. If the dryer is stacked, under cabinetry, or gas‑fired, pro service ensures safe disassembly and reconnection. Expert repair eliminates guesswork, ensures correct OEM part replacement, restores heating, and prevents dangerous overheating.
