sixcow RV Refrigerator Thermistor Kit for Dometic RM Series — 2‑Wire 10K NTC, 50.5" Cable

Replacement thermistor kit designed to restore accurate temperature sensing in Dometic RM-series RV refrigerators with a 2-wire 10K NTC sensor.

If your Dometic RV fridge is running too cold, too warm, or cycling oddly, the problem is often a degraded thermistor sensor. This sixcow 3851210025 replacement kit fits a wide range of RM-model refrigerators and reproduces OEM fit and electrical characteristics so your fridge can read temperatures reliably again.

Which Dometic models will this thermistor kit work with?

This kit is made for Dometic RM-series refrigerators that use a two‑wire thermistor. It directly replaces several OEM part numbers and covers many older and current RM model numbers.

• Common compatible models: RM1350, RM2351, RM2354, RM2410, RM2620, RM2652, RM2852, RM2862, RM3807 and others in the RM family.
• Replaces part numbers such as 38510590422, 2931863035, 2931863076 and 3851059042.
• Intended for units that accept a 2‑wire 10K NTC probe and the matching plug style.

How accurate and durable is the sensor for RV use?

The thermistor uses an epoxy‑sealed probe and double-layer sealing to resist moisture and mechanical stress common in mobile applications. Its rated operating range and construction help it hold up to temperature swings and vibration in RV environments.

• NTC probe size: roughly 8.1 × 29.6 mm with epoxy resin encapsulation.
• Temperature range: -20°C to 105°C for reliable sensing across refrigeration demands.
• Cable: 24 AWG two‑wire, 50.5 inches long for flexible routing inside the fridge compartment.

Will this part fix temperature problems like freezing or spoilage?

Faulty or intermittently failing thermistors are a common cause of incorrect fridge temperatures. Replacing a worn sensor with this sixcow kit often resolves issues where the controller receives incorrect readings and then overcools or undercools the compartment.

• Restores accurate temperature feedback to the control board to reduce overcooling or warming cycles.
• Direct electrical match (10K resistance) to minimize installation complications.
• Plug design matches OEM connectors to allow straightforward replacement.

What are the technical details I should check before buying?

Confirm your refrigerator uses a 2‑wire 10K NTC thermistor with the matching plug and that one of the listed RM model numbers or part replacements applies. Measuring the old sensor or comparing part numbers ensures correct selection.

• Resistance: 10K NTC sensor characteristic for typical Dometic controllers.
• Plug: compatible with 1586019-2 style connector used in many RM units.
• Cable length and probe size: 50.5" cable; probe approx. 8.1×29.6 mm—check fit for routing and mounting.

Who this is for: RV owners, mobile home technicians, and DIYers who need a direct replacement thermistor for Dometic RM‑series refrigerators. If your unit shows erratic temperature behavior, displays incorrect cooling, or you want to restore original sensing performance without replacing the whole control assembly, this sixcow replacement kit provides a cost‑effective, OEM‑compatible option. The product includes a satisfaction guarantee and limited warranty to support installation and initial performance verification.
