Refrigerator cooling fans

I have seen the fan switch located on the evaporator fins on my Norcold 12xx series box. I think I heard the fans run one time when I first started the refrigerator but that was last year.

However, in over a year of full time living in the rig I can't recall ever hearing them come on again. I may have mistaken the converter cooling fan operating for what I thought was the refrigerator fan(s).

The question is, do we have cooling fans under the refrigerator? I have the fan switch with wires but I haven't seen or heard any evidence that a fan is present. I think I've seen an exploded view of these refrigerators with two muffin fans located beneath the refrigerator.

Either the switch or fan is bad or not present or the evaporator hasn't been hot enough (even with high ambient temperatures) to need cooling.

Any input on this topic from you guys or gals?

Sundancer.

Your referigator is not in a slide therefore you will not have cooling fans. I believe your unit has a roof vent.

I was thinking that was the case so they must automatically stick the fan switch and wires to all the refrigerators, not knowing if it fits in a slide or not.

Do they put the four door in a slide?

Rig has a roof vent, that's how I saw the fan switch when I was replacing it.

Also, the open space above the refrigerator that makes the channel for the roof vent is poorly made and does require a real tape job as it is about as bad as the A/C duct work.

Mystery solved! I do have refrigerator fan(s), I do!

Due to diagnostic processes I've been running the refrigerator on propane and indeed the fan or fans come on, runs for an amount of time and then shut down.

Never heard them after the first time because I've been using electricty to cool the thing.

I was just about ready to order a residential to replace the 1210 Norcold but I decided to do some diagnostics first. I'm sure I have discovered the problem, a 20 dollar part that could and is probably missed many times and therefore causing an owner to replace the refrigerator or the absorption unit.

To my knowledge, ALL 1200 series have these fans. They work on electric, or gas whenever the a certain temperature is reached. Can't tell you what the temp may be, the button thermostat opens as shown in picture activating the fans. If you don't have these fans, or they're not working.... YOU have a problem!

You may, or may not hear them run. I could hear mine. If the temp sensor fails it can and will overheat .... thus activating the high limit switch installed as a fix all.. yea right shutting your unit down decreasing the chance of fire ... NOT eliminating it. Most fires to my knowledge are caused by cooling unit failures.

Thanks for the photos Slim. I didn't start hearing the fan(s) until I switched over to gas yesterday during the diagnosis, never heard them on electric for nearly the whole year.

Aha, just went out there and contorted myself like a dog scratching fleas and looked up there and there they are. So, slide out or not, a 1210 has them.

They are more likely to run in gas mode as more heat is created than when in electric mode. (heating elements).

ANNNNND.... if your fans seem to run all the time like mine did... you might check the vents on the outside of the coach, lower and upper. Annnnd, you might find that the mentally impaired painters at Dutchmen forgot to remove the tape they used to cover the inside of the vent while doing the full body paint. Is there really ANYTHING that they do well at Dutchmen?

WAY!!! The fans ran all the time. When it was in for all the slide work I mentioned it to the tech's and they found the upper vent was still covered with tape on the inside. All the heat was being trapped inside the fridge compartment. I've said it before.... NEVER AGAIN!!!

They are consistent at being poor workmen. IE: good at poor workmanship
