RV Thermostat Replacement 3106995.032 – That One XZHJJF
This analog RV thermostat replacement is designed for Dometic systems, offering a straightforward control scheme for Cool, Furnace, and Fan operations. The model supports a temperature range from 0 to 30 degrees Celsius (40–90 degrees Fahrenheit), enabling practical comfort management for varying climates. It operates on 12 VDC, suitable for most RV power setups. The built-in fan control allows continuous operation to improve air circulation, particularly useful in hot stops where even airflow can reduce hot spots inside the RV. Installation is typically compatible with older RV layouts that rely on analog temperature sliders, making it a practical replacement option for replacement parts or upgrades to prevent system downtime.
Key considerations: verify that your RV uses a 12 VDC control with Cool/Furnace/Fan options, and confirm wire routing aligns with the existing control board. If you need a simple, no-frills thermostat with reliable fan operation, this model provides that baseline functionality. For users prioritizing analog control and a familiar interface, this unit remains a solid option for maintenance or upgrades.

Buying Guide: Key Purchase Considerations And Comparisons
When selecting an RV air conditioner thermostat, several factors influence the best choice for your setup:
- Compatibility: Verify that the thermostat matches your HVAC brand and model (Dometic, Coleman Mach, Roughneck, etc.). Some units are designed for three-wire systems, while others support more complex wiring. Always count wires before ordering.
- Wiring and Installation: Look for color-coded wiring and clear installation instructions. Six-wire configurations are common for easier wiring, while capacitive touch interfaces require attention to proper power and grounding.
- Control Type: Decide between analog sliders or digital touchscreens. Analog thermostats are simple and reliable, while digital and capacitive touch models offer modern interfaces and features like backlit displays.
- Temperature Range: Ensure the thermostat’s range covers the climates you frequent. Most RV units operate effectively within a typical RV range, but some thermostats emphasize certain Fahrenheit/Celsius conversions or sensor types.
- Functional Scope: Check which functions are supported (Cool, Heat, Furnace, Fan, Heating Strips). Some models control gas/electric strips in addition to standard cooling and heating.
- Ease of Upgrade: If updating an older system, consider models specifically marketed as replacements for your existing thermostat part number, such as 7330G3351 or 3316250.712, to minimize wiring changes.
- Display and Usability: Blue backlit LCDs and capacitive touch controls improve readability in low-light conditions common inside RVs at night.
- Reliability and Support: Look for models with documented compatibility notes and wiring guidance to reduce installation time and troubleshooting needs on the road.
In summary, the best RV thermostat depends on your existing air conditioner model, wiring configuration, and preferred interface. For broad Coleman Mach or Dometic compatibility, options like the 7330F3852 family and the 3316250.712 variants offer robust support, while more traditional analog models provide a dependable, straightforward replacement path. Consider your wiring, desired control type, and the climate you usually face to choose a thermostat that maintains comfort wherever your RV takes you.
