Repairing a Samsung Quatro Refrigerator

Join Samurai Appliance Repair Man on a repair safari into Refrigerator Land. In this scintillating video, I narrate a series of photos I took during a service call I did on a Samsung Quatro refrigerator. These are unusual refrigerators because they have four evaporators (hence the marketing name "Quatro"). In this service call, I fixed problems with two of the compartments-- fortunately, both on the same side!

Brilliant. Absolutely brilliant. Thanks.

Question please Scott. You stated you had to return later to allow the ice to melt and seperate from the back panel in order to remove it without cracking it.

Do you think it would be possible to scan it with an IR gun to find the coldest spots (signifiying where the ice is sticking most) on the rear panel and then hitting those areas with the steamer from the outside?

Kind of like the harvest cycle of an IM. It may create just enough of a melted film of water to release the panel without damage.

I realize nobody would want to have to pay for a new panel. Slow and steady though. Plus having never worked on one and not knowing what the layout is behind the rear panel, would be cause for "playing it safe".

Also, do you think the steamer may deform the rear panel while deffrosting?

Just curious if you think this may work, to spend extra time on the first call and not having to return at another time.

Domo, Brother Beam, and great questions!

 

Do you think it would be possible to scan it with an IR gun to find the coldest spots (signifiying where the ice is sticking most) on the rear panel and then hitting those areas with the steamer from the outside?

 

 

This is a good thought but, in this case, I knew the ice was at the bottom section because the cover in the top part bowed back.  

 

The other thing is that in this model the evaporator cover has several layers with a metal backing so the plastic surface temperatures would not have necessarily reflected the temperatures in back of the panel.  This also means that applying steam to the outside of the evaporator cover would not have had any effect on the ice behind the evaporator cover. 

 

 

Also, do you think the steamer may deform the rear panel while deffrosting?

 

 

 

No.  In fact, this is one of the beautiful things about the steamer compared to hot air.  Hot air absolutely WILL deform the plastic unless you're very careful.  With a steamer, you would have to work really hard to get the plastic to deform.  

 

Just curious if you think this may work, to spend extra time on the first call and not having to return at another time.

 

 

 

I was dealing with a particular type of failure that caused the excessive ice formation on the evaporator.  Many other failures do not result in the excessive ice.  For example, the compartment thermistor could have gone out of cal causing warm compartment temperatures but without the failure of the bimetal in the defrost heater circuit.  The result would have been a very simple repair that, for this model, would not have even required removing the back panel.  So, it all depends on the exact nature of the failure and its effects.

Thanks for the feedback. Duh, I did not even think of the panel thickness. I personally have not worked on one of these yet, but it looks very challenging.

I was using the old hair dryer method up until a year or so ago, then saw the steamer here and gave the hair dryer an early retirement. What an awesome tool these steamers are. I was concerned about the close proximity and the amount of steam required to try to melt from the outside.

Great points you made here. Are the service manuals available for this particular flavor? Would love to study up on these. Thanks again.

Here's the silicon grease I use:  https://www.amazon.com/Synthetic-Grease-Syncolon-Purpose-Lubricant/dp/B000XBH9HI/ref=as_sl_pc_ss_til?tag=mrssamskit-20&linkCode=w01&linkId=&creativeASIN=B000XBH9HI

 

The "Drycon" pre-greased twist-on connectors and the crimp-style bell connectors are both available at your local hardware store.

Great video! I often wondered about the Samsung thermistors, if they were interchangable like the GE thermistors. Now I know, thanks!

Before Whirlpool bought Maytag, Maytag was contracted by Samsung for their Service Support in the states.  After Whirlpool took over they cancelled that contract. Here's they Maytag Technical Institute version of the original Samsung 2 door 2 drawer Convertible Side by Side Training Manual.  This in addition to the Fast Track is all you need for battle.

Thank you for this video. I am working on this exact model and I am getting cr/ cooling room fan error but I am not sure which is the fan since I see there are 2 fans total in the freezer. Could you point me in the right direction?
