Refrigerator Fan Question

[sealevel_ram]

I have a Norcold 1210 refer.

Is it normal for the fan to run all the time?
I have changed the temperature to the lowest setting and nothing happens. I know the cooling part cycles, but I continue to hear a fan noise no matter what the setting is.
It happens on electric or propane.

Is this normal?

The unit is a little over a year old and is out of warranty (of course), and I never noticed the fan noise until my last trip.

The refrigerator has started showing "LOW AC" when I have a lot of lights on, which may be a symptom of another problem.

Thanks

Our reefer is in a slide. The OEM fans were sleeve bearing type. I replaced them with Enermax fans from Amazon. They sport magnetic levitating non-contact bearings, so they are very quiet and draw very little current. I bypassed the fin button with an attic fan thermostat from Lowe's. The thermostat is adjustable, I've set ours to come on in the 90's. The fridge runs low single digits freezer and sub 40's chillbox. We never hear the fans when inside.

Interested in which fan models you purchased as our new trailer has its Norcold fridge on a slide and we are not used to hearing the fan noise because our previous trailers did not have fridge fans.

In Fla it could be normal even in November. I would wait until a cold morning to decide if you have a problem.

Norcold OEM Fan T-stat turns fan(s) ON at 130*F and turns fan(s) OFF at 115*F
(Condenser FIN Temp NOT ambient air temp)

IF fridge is installed in a slideout you can access t-stat via upper sidewall vent/access cover

If NOT in a slideout....have to pull fridge to access t-stat & fans

The external fan is controlled by a simple snap disc thermostat affixed to an outboard cooling fin on the upper condenser. It might be bad and it's easy to replace and replacements can be had on Amazon, Dell Electronics or DigiKey.

You do need to determine what it's rated for temp wise however and that will rake a look see to determine.

The external fan could run constantly, depending on the ambient outside temperature in the outside fridge cavity and of course how hot it is where you camp. Lots of factors impact the fan on and off sequence.

On mine, the fans tend to run all day and shut off at night when it's cooler. I say fans because I added one, 2 or 3 is better than one in this case...and yours.
