Description
Dometic 3312303.005 is a thermistor wire assembly service kit for compatible Dometic Penguin rooftop air conditioners and heat pumps. Dometic's own 2024 Climate Control Service Parts catalog identifies this exact part as a service thermistor wire assembly rather than a general-purpose air-conditioner wiring harness.
Part identification
- Manufacturer: Dometic / Duo-Therm

- Component: Temperature-sensing thermistor wire assembly kit
- Documented service-parts example: Penguin 630515331 heat pump

Fitment and ordering
Compare the original thermistor wire assembly, connector shape, sensor position and complete rooftop product ID before purchase. Dometic service diagrams for Penguin heat-pump models identify this sensor wiring separately from the fan motor, ambient-air sensor and primary control board. A broad Penguin series name alone does not confirm fitment with every production revision. This is not a whole-unit power harness or thermostat replacement.
