GE GTD42GASJ2WW 7.2 cu ft Gas with HE Sensor Dry MECH-FUSE Error Fix: Dryer Will Not Start at All — Blown Thermal Fuse

Error code MECH-FUSE on the GE GTD42GASJ2WW 7.2 cu ft Gas with HE Sensor Dry means: Dryer Will Not Start at All — Blown Thermal Fuse. The dryer has no power response at all — no lights, no drum rotation, nothing — the thermal fuse has blown; this is a one-time-use safety fuse that blows when the dryer overheats due to restricted exhaust airflow; the fuse is typically located on the exhaust duct housing or on the blower housing inside the dryer; CRITICAL: always clean the dryer vent duct before or immediately after replacing the thermal fuse — the clogged vent is what caused the fuse to blow and it will blow again if not addressed
