The Jelrus 06/00 Muffle is a high‑temperature ceramic enclosure used in porcelain and dental furnaces to protect the heating elements from direct flame contact. Common failure modes for this unit include cracked or warped muffle walls due to thermal shock, degraded O‑ring seals causing vacuum leaks, and electrical faults in the associated thermocouple or heater connections. First‑check diagnostics: verify that the furnace power supply is delivering correct voltage and current; inspect the muffle for visible cracks or warping, and confirm all mounting bolts are torqued properly; check the thermocouple and heater wiring for continuity and proper insulation resistance before re‑energizing the unit.[oss-gpt-20b] |
