This unit is about 3 yrs old.

In mid November my wife noticed water leaking from the freezer.   It appeared that the condensate drain must be plugged.   I removed the ice, cleaned the drain, all appeared to be well.   Had good refrigeration.

Today the freezer was warm.  The evaporator was completely frozen.   I defrosted it with a hair dryer.   The evaporator fan works.   It refrigerates well.  How do I troubleshoot this?

While the unit was under warranty, had a similar problem, the tech wrote that he replaced the "Defrost Terminator???" (he wuz knot a very gud speler :)  so I'm guessing that is what was done.)  This is a dime size sensor mounted on the back panel inside the freezer.

Your tech's spelling was just fine-- "defrost terminator" is a valid designation for that part, also called a "defrost thermostat," which is an overly-glorious term for what this part actually does-- terminate the power to the defrost heater in the event that something goes wrong.

Jambatt linked you to a useful reference. Use it and your meter to test the defrost terminator and the defrost heaters for continuity.

I reviewed your diagnosing defrosting problems page and pdf.

I'd like to know how to put this unit into defrost mode - I believe it's done through the control panel by pressing several of the buttons (display / alarm, etc) - I was looking for that info.

Also the defrost terminator - is it supposed to be normally open or normally closed?

I have heard that this was an Amana design that was sold to Viking.

Could very well be Amana-built, in which case, all the more reason to check that defrost terminator-- a common culprit for this very problem in many Amanas. Should be closed at freezer temps. The operating temps are printed on the side.

But look closely at it-- if it looks like this, then, as my underworld apprentice, Rocko, would say, fuggetaboutit (it's bad).

Check that out and we'll go from there.

I replaced the defrost terminiator in Jan.   Put it all back together. 

I have the same problem today - it defrosts, but doesn't drain, instead in freezes right below the evaporator, and eventually floods the freezer floor.

What is responsible for the defrost?   Is it the heating element below the evaporator or is it hot gas?   I'm mistified?

sounds like you defrost is normal , but the water is not going down the drain . can you see the drain hole ?  is there ice in it ?  . think about it: THAT DEFROST WATER HAS TO GO SOMEWHERE   , sounds like its not going where it should , DOWN THE DRAIN  .   the cure :  hair dryer , hot water and towls for the mess

About March 15th, I once again removed the frozen condensate.  Drain is completely open - poured a cup of hot water down it.  Went right through.

Evaporator is clear, no frost.

I wrapped a 12 gauge Aluminum wire around the calrod, and routed it down the drain hole.  Today, I see it's still freezing up!!

I've relplaced the defrost terminator.

My question is: Does the cal rod defrost the evaporator?  Or does this unit use another method (like hot gas?).  What else is there to replace?

The unit is about 3 yrs old - it just started doing this 5-6 months ago.

i do not know your fridge but i have worked on more than a few vikings , and i do know all about hot gas defrost . you need at least 1/2 hp compressor to do hot gas defrost and you dont have it your is 1/3 hp  . if you have a cal rod then thats what defrosts it . the last home fridge i have seen with hot gas was 1964 sears coldspot side by side and it needed a oddball 5 min defrost timer . . i think you can take to the bank thats its electric heat defrost ..... now on your problem with the drain . your not the first person to have the drain problem with the vking ,  the ice maker fill tube will freeze up too , and all i can do is defrost them and a few months the problem returns. i would contact viking , as of yet i have not heard of a fix , but see what a factory tech says . if you get a fix , PLEASE post it here . thanks and good luck   BOB

yep the calrod is whats defrosts the evap. coils. Since you have already installed the aluminum wire on the calrod and it did't completely solve your problem I would contact viking  ( or an authorized tech.) for further instruction
