Serial and revision scopeArctec manual 0315401, revision August 21, 2008. Confirm the exact door serial number and installed assembly with Rytec; the manual warns that product changes and special engineering can change the fitted parts. This is document-based identification, not an installation procedure or universal fitment.
Heater voltage selection0304420 is listed at 1,100 watts and 460 volts; 0304421 at 1,100 watts and 230 volts. Both rows have quantity two. Equal wattage does not make the heaters interchangeable.
Thermostat unitsThe 100-degree and 180-degree thermostat labels do not state a temperature scale. Neither Fahrenheit nor Celsius is assigned.
Drive cross-reference discrepancyThis list names left drive 0399438 and right drive 0399416; the dedicated breakdowns name 0399514 and 0399520. No alias, successor or complete-door fitment is established.
