Dometic 2662RBX supplemental fan install - 2017 Imagine 2600RB

[Rivercityjeff]

Our Dometic 2662RBX has not had an issue maintaining cold temperatures. However, the unit is 3 years old. I would like to get another 3-5 years before we change RV's and figured adding a cooling fan would help.

The fan kit was purchased from RV Cooling Unit Warehouse for $48.95 plus shipping.

Cheap insurance. As per guidance from RV Cooling Unit Warehouse, I mounted the fan to supply air vs. exhaust air. The 2600RB has a roof exhaust vent vs. upper side panel vent.

1. Find a power source and Ground. Note the 12V Terminal Block, it was marked 12V, +, and -

2. Mount fan with included L brackets.

3. Mount Thermostat with CA glue and cable ties.

4. Mount Switch and Fuse. Cut and crimp wires. Seal screws in the wood with silicone.


I tested the power connection by jumping the 130 degree F thermostat. It works. The whole process took 30 minutes.

Thanks for this post. I have been thinking of adding a fan and this seems quick, easy and no roof work. So after reading your post I ordered the same unit.

Is this fan relatively quiet? Mine has a fan from factory, but it is loud!

It is as quiet as computer fan. It can be heard outside. Yesterday, frig set at 4, -11 degrees in the freezer. Works for me!

Sounds (sorry[emoji57]) like it works good. Did you leave the oem fan in place? Does it stay off because of the flow of the new one? I am ready to do this as the oem fan is so loud it spoils my boondocking quiet.

We left the original factory fan in place. On our 2600RB we may to pull the frig to access it? We have never heard the factory fan.

FYI, on mine we had marginal cooling in hot summer temps. I found the fans installed by GD were not running. The issue IMO, is the location of the temp switch, its too far out on the fins. I bypassed it, got the fans running and this made a significant improvement. IIRC we had a 20° decrease in freezer temp. Later I found the same switch with a lower temp rating and installed that. So, IMO, the installed fans are adequate if they are running when they should be. Good luck

UPDATE:

Pulled into an RV park in Texarkana, Texas. Temp was in the mid-90's, Frig set to the 4th dot. Plugged in the power, Frig and Fan engaged. Freezer temp -3F Frig Temp 34F (after removing two adult beverages).

The mod works well for us.
