Venting refrigerator heat with fan

I don’t know what comes with new trailers but ours with the 3-way Dometic had a vent fan with on/off switch installed at the factory.  Mike

My Dometic refrigerator also came equipped from Oliver with a vent fan in 2017.  And as Mike said, it also has a fan switch on the main panel just inside of the door.  With the fan switch on, power is sent to a thermostat which then sends the 12v power onto the fan.  So even if the switch is in the on position, the fan will not run until the thermostat reaches a set temperature then it comes on and shuts off when it cools to a set temperature.  Mine usually shuts off at night and back on in the morning when it warms up.  There are fan kits available on the internet as well as YouTube video’s on how to install one.

Has anyone added a vent fan at the heat vent outlet of their refrigerator?

 

Many people have done that if their 3way doesn't have an exhaust fan built in. Our original 2008 Norcold did not have a vent fan, and some dometics don't either.

You can find a myriad of solutions on YouTube. Some folks have just attached a small clip on battery powered fan to the upper vent to increase exhaust when camping in the heat.

Other friends have also installed little fans inside the fridge to better circulate the cold air. I'm thinking about adding one to our DC compressor fridge, as I generally need to unlosd and defrost it every 10 to 15 days, as the frost buildup in the freezer can impede operation of the freezer door. (Broke the door once already due to this.)

Mine came with the fan but I can't find an on/off switch.  It does come on during the day shuts off at night.

I learned that some Dometic RM2454 fridges have cooling fans located between the upper and lower coils, in an area that is completely inaccessible without removing the unit entirely. Jason in Service told me that they started receiving these units in mid-2017 (mine was delivered in May '17), and that previously there was NO Dometic fan installed. On those units Oliver added their own fan, positioned up high above the upper coils where it was easily reached, and I believe these fans also had an inside On/ Off switch. Yay! Good thinking.

@johnwen, you night open a ticket and share the results.

I "think" the current norcold may have an internal fan, to decrease frost buildup on the fins.  I've not seen one, so unsure.

Maybe Oliver is still installing  an exhaust "lift"  fan. I  really don't know . Most people probably won't find it necessary,  but the extra lift would help those who routinely camp in high temp conditions.  Not my cup of tea.

I found the 1 lone fan under the cooling fins behind the top outside access panel (using a mirror), no switch.  But, if need be (as in, fan too noisy), I see the where I can maybe install my own switch.
