Iced up Refer

[Kimberly Flores]

We are in a very humid area and the interior cooling fins of my fridge are iced up.

Should I do something (defrost) or just leave it?

You will probably need to defrost if the cooling has stopped. Really shouldn’t take long to thaw out the frig. Also look for some kind of fan to place near the fins so air can circulate and hopefully stop some of the frosting up. Also make sure you have good circulation on the back of the frig and not some blockage of the vent that travels to the top of the camper.

I found that it didn’t take long to defrost the fins when one of mine froze up. But after finding a battery powered very small fan for the inside of frig my frosting up pretty much stopped.

If we get a cooler day I might defrost it but it’s still cooling.

I do have a fan inside.

The air is very humid so that moisture sneaks in every time the door is opened.

Of course I could just move on to a dryer climate and problem solved.  :yes:

Mine iced up solid a few times this last summer. I just take a hair dryer and wave it back and forth across the fins making sure to not leave it too long in one spot.

I’ve been told getting it too hot could possibly lead to a problem with the backing plate sealant material. But I’ve never had an issue. The fins and aluminum back plate are still plenty cold even when the ice is melting off.

yea I got Eddie’s heat Gun and thawed mine. That  was on that ole Cougar though.

Starting to finally cool down and act like autumn around here, so I guess it’s safe to get the ol hair dryer out.

I was just wondering if it wasn’t good for the fridge to be in that condition.

Thanks!

I’d say the fins are there to maximize the surface area for cooling so having them gummed up with ice will reduce it for sure, in turn, the fridge will have to work harder to cool, which over time is a bad thing.

There is a small thermocouple clipped to one of those fins and it’s not uncommon for it to fail, especially if a hair dryer has been used previously to defrost the fins.  If the thermocouple failed then it isn’t allowing your fridge to turn off when it gets to temp and the fins will collect frost.  I’ve had this happen twice and it’s an easy fix not to mention probably the cheapest thing that can go wrong with your fridge.

Thanks Joe. I replaced that bugger a long time ago with an adjustable thermistor, like this one on ebay: https://goo.gl/kUecJM

The main culprit was the humidity. Wet air sticking to the fins.
Defrosted it and it should be good to go now that the weather is changing over here.

I would check the door seal also.
