Jelrus Multi-Stage MSM furnace

Jelrus Multi‑Stage MSM furnace is a 115 V dental burnout oven capable of programmable three‑stage burnouts with a built‑in delay start for nighttime operation. Common failure modes include loss of the delayed start function (often due to a faulty timer plug or control board logic), overheating or inaccurate temperature readings from the thermocouple, and intermittent heating element faults. First‑check diagnostics: verify 115 V supply and continuity on the delay‑start circuit; inspect the timer plug and associated relay contacts for wear or burn marks; review any error codes displayed on the control panel and compare with the manufacturer’s troubleshooting guide.[oss-gpt-20b]
