Understanding the Problem
The DC96-00887C is a thermal fuse (also called a thermal cutoff) commonly used on Samsung dryers. Its job is to permanently interrupt power to the heater circuit if the dryer overheats. When the thermal fuse blows, the dryer usually stops producing heat (or in some models won’t run at all). Before replacing the fuse you must find and fix the root cause of the overheat (usually restricted airflow or a failed thermostat). 1. Preliminary checks and tools - Tools: multimeter, flathead and Phillips screwdrivers, nut driver (1/4" or 5/16" depending on model), needle-nose pliers, replacement fuse (DC96-00887C), camera/phone to document wiring. - Safety first: unplug the dryer from power. For gas dryers, turn off the gas supply as a precaution. 2. Confirm the fuse is bad (diagnostic steps) - Locate the thermal fuse: typically mounted on the blower housing or on the heater housing behind the rear access panel or lower front panel. - Remove the access panel(s) to reach the fuse. Take a photo of the wire connections to ensure correct reinstallation. - With power still disconnected, remove the two quick-disconnect wires from the fuse. - Test for continuity with a multimeter set to ohms: a good fuse shows near-zero ohms (continuity); a blown fuse shows infinite resistance (open circuit). 3. Inspect and correct underlying causes (must do before replacing) - Check the exhaust vent and lint trap for blockages; clean the lint screen and disconnect and inspect the vent to the outside for lint buildup or crushing. - Inspect the blower wheel for lint buildup and the heater element for signs of shorting or distortion that could cause overheating. - Verify the cycling thermostat and high-limit thermostat are operating correctly (these can also fail and cause overheating). 4. Replacement steps (how to fix) - With power disconnected, remove the dryer access panels to expose the thermal fuse. - Note or photograph the wire orientation, then disconnect the two wire terminals from the old fuse and remove the mounting screw or clip. - Install the new DC96-00887C thermal fuse in the same position and reattach the wires to the correct terminals. - Reassemble the dryer panels and reconnect power (and gas if applicable). - Run a test cycle with no laundry and monitor for normal heating and airflow. Re-check venting if the fuse blows again. 5. Final checks and what to expect - If the new fuse immediately blows, do not keep replacing it — there is still an overheating condition or a shorted heater element or thermostat that must be repaired. Safety note: The thermal fuse is a one-time safety device. Never bypass or bridge it to make the dryer run — bypassing creates a serious fire risk. Always disconnect power before testing or replacing parts and correct airflow/thermostat/heater faults that caused the fuse to blow.
Common Symptoms
Dryer runs but no heat, dryer won’t start heating, dryer stops mid-cycle, or the dryer blows the thermal fuse repeatedly after replacement.
Common Causes
- Clogged or restricted venting / lint buildup causing overheating
- Failed heating element or short that overheats the heater circuit
- Faulty cycling thermostat or high-limit thermostat failing to regulate temperature

Helpful Repair Tip
Before replacing, remove the quick-disconnect wires and check continuity with a multimeter; an open reading (no continuity) means the DC96-00887C is blown and must be replaced. Also clean the exhaust vent first — poor venting is the most common cause.
Frequently Asked Questions
Can I bypass the thermal fuse to get the dryer running?
No. The thermal fuse is a critical safety device that prevents dryer fires by cutting power to the heater when temperatures get unsafe. Bypassing it creates a fire hazard and is not an acceptable repair. Replace the fuse and fix the underlying cause of overheating instead.
How do I know if the DC96-00887C is the cause of no-heat?
Unplug the dryer, access the fuse, remove the two quick-disconnect wires and test continuity with a multimeter. If the meter shows open (no continuity), the thermal fuse is blown and will cause no-heat. Always inspect and clear the vent, check the heater element and thermostats before replacing the fuse to prevent immediate re-failure.
