Dometic RV Refrigerator Cooling Unit 4450006433 – Type 409C (RM2454)
This Dometic replacement cooling unit, part number 4450006433 (cooling unit type 409C), is for Dometic RM2454 refrigerators. It replaces the previous Dometic part number 2934409091. It's a complete replacement for a failed or leaking sealed cooling system, and your existing refrigerator controls and heat-source components stay in place.
Signs your cooling unit has failed
- The refrigerator won't cool on any power source, even though the heater or flame is working
- A strong ammonia smell, or yellow powder or residue on the back of the refrigerator (a refrigerant leak)
- The boiler area is hot but the freezer fins stay warm
Before replacing the cooling unit, rule out simpler causes: heating element, LP flame and burner, thermostat or thermistor, ventilation and leveling.
Important compatibility information
Dometic built RM2454 refrigerators in several configurations. Before ordering, check your refrigerator's model number and product number on the data label inside the fresh-food compartment. Send them to us if you'd like us to confirm the fit.
Installation overview
Plan on several hours. You'll need to shut off the LP and disconnect AC/DC power, remove the refrigerator from its cabinet, unscrew the evaporator inside the freezer and the cooling unit at the back, transfer heat-source components as needed, clean the old thermal mastic from the evaporator mounting surface, and mount the new unit with fresh thermal mastic. Then reverse the steps.
