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

sixcow 3851210025 is a direct-fit replacement thermistor kit for Dometic RM-series RV refrigerators that restores accurate temperature sensing with a 2-wire 10K NTC probe and 50.5” cable.

If your Dometic RM-series refrigerator is cycling poorly, freezing food, or failing to reach set temperatures, a worn or damaged thermistor is often the culprit. This sixcow replacement matches the original form and function for many Dometic RM models (including RM1350, RM2351, RM2354, RM2410, RM2620, RM2652, RM2852, RM2862, RM3807 and more) and is built with epoxy-coated probe and double-sealed wiring to resist moisture and flexing inside an RV environment.

How will this thermistor kit improve my fridge’s temperature control?

Replacing a faulty thermistor restores the accurate temperature feedback that the refrigerator control board needs to modulate cooling cycles. That prevents over-freezing or inadequate cooling caused by incorrect sensor readings.

• NTC 10K probe for consistent resistance-to-temperature response.
• Epoxy resin-coated probe improves insulation and signal reliability.
• 50.5” 24AWG two-wire cable provides reach and flexibility inside cabinets.
• Direct compatible with OEM part numbers like 38510590422 and 2931863035.

Will this part fit my Dometic RM refrigerator model?

How durable and weather-resistant is the replacement thermistor?

The probe and wiring are made for rugged RV conditions where vibration, humidity and occasional flexing are common. The kit uses double-layer sealing and environmental epoxy to keep the probe stable and waterproof within the refrigerator cavity.

• Epoxy resin coating for moisture resistance and wear protection.
• Double-layer wire sealing reduces risk of failure from bending or abrasion.
• Operating temperature range from -20°C to 105°C for wide environmental tolerance.

What installation and technical details should I know before replacing it?

Installation is typically straightforward for DIY RV owners comfortable working with appliance connectors: disconnect power, remove the old probe, match connector and probe size, and route the new cable to avoid sharp bends. If you’re unsure, consult your service manual or a qualified RV technician.
