Re: Ice Build up??
Okay Gary that clears up alot of confusion with the solenoid. What is the solenoid thats on the refrigerant line? Is that so the freezer does get too cold....is that why its wired to the thermostat?
Here are the pics of the valve and thermostat.

Re: Ice Build up??
Wackie.
I am confused with the pic of solenoid, could be a hot gas defrost injection solenoid valve. Is it masking/hiding the suction line.

Re: Ice Build up??
Dont know what it is Magoo...i just know its wired in with the thrmostat in the other picture. And i do her it click over the course of the day. What does this mean ??

Re: Ice Build up??
About 6 months ago I had a Traulsen upright freezer with ice forming all around the evaporator but never on it. The tech support guy at Traulsen had me decrease a setting for the defrost termination to decrease the temperature at which defrost was terminated. It was his idea that the coil was defrosting, creating too much steam from reaching too high a temp before cutting back on, and causing all that water vapor to refreeze an build up on the sides of the box housing the evaporator.
This is a bit off from my memory, but it was changed from something like 70 to 40. This unit had the computer with the red numbers and the codes and all the "sD, sP, etc."
I don't remember which code it was, but I never got a call back after that.

Re: Ice Build up??
Truenilbog i have the same exact problem. Today i walked into my store and she had iced up and i had to shut it down and move everything out into my other freezer. Luckily it had just happend all the stuff inside was still solid.
I shut down the compressor and left the heaters plugged in, i turned the timer to cycle a deforst. When i did this i put my hand up the return air side i could feel the heat on the bottom of the pan....it had to be 130 degrees....it was extremely hot. I have to call them about this. We also dont have a termination switch too.
I have a firly old one (15-16 years) so i dont have anything digital on it.
How is the freezer running now???

Re: Ice Build up??
Hi wackie.
I have been working out of town for a while, so haven't been keeping up-to-date with your problem.
But truenilbog may have touched on real problem.
130+ F around evap is way too hot.
From earlier posts you seem to have a Paragon defrost controller. The screw in pin things initate defrost and then time terminated.
The terminate timer is the outer disk thing indicating minutes, the set is changed by depressing the arrow thing and moving around at the same time. Even 40 minutes is along defrost, depends on how many defrost per 24 hour period.
On average 4 per 24 hours, so every 6 hours, you can change these around to have less when closed over night and nobody opening and closing the door.
Keep in touch.

Re: Ice Build up??
as magoo says plus you want termination temperature no greater than 10 deg.C.try with 12 min period,increase or decrease time period as necessary until you have fan delay/defrost termination klixon and over heat safety klixon correctly wired and operating.

Re: Ice Build up??
Wackie.
just to add to the confussion, some paragon defrost controllers have pressure termination. So you have time initiated and time terminated but with pressure terminate over ride. They have a copper pipe connected into bottom of paragon controller.
As before a pic saves athousnad words.
Keep in touch.

Re: Ice Build up??
Hey People, sorry I been out of touch.
I ordered the termination switch, opend the freezer and found that they cut of the termination swithc and just wire nutted the 2 ends together. I hooked the new switch up, check all the wiring.
Now came the purple wire that wasnt hooked up. And as Gary said i needed a new timer. I have the 8041-00 that from what i see online works on time. I needed the 8041-00 which has the temp termination. So i ordered the new one. I will install monday, hopefully all works well.
The tech from the company was surprised i didnt have the 8141....i guess one of these fools over the years swapped it or maybe it was the wrong movement in the wrong box. The label in the box says 8141 the timer itsefl says 8041. Thats what confused gary in my previous posts.
I will keep you guys posted on what happens.
Thanks again for everything

Re: Ice Build up??
Hey People,
So I did what Gary said and got the rigth timer. I installed it and it wasnt turning. I called techs at traulsen went over the wiring everything was okay. So i called the people who sold it to me told them it was defective. I got a second one...somehow they sent an expport model. The dealer said it was okay but paragon said that one was not to be used int he US. So i got a non export 8141-00 hooked it up and put it. She runs like a Rolex
Today i came in and no ice build up! Hoping it stays liek this over the weekend.
Does the termination switch just shut the heater and wait for the timer to cycle out of defrost? Or does it trip it out of defrost and throw it back into freezer mode????????????
Now it just seems to shut the heater and waitt for it self to time out. Either way it seems to be working....i just dont want any problems in the long run.
Thanks for all the help people!!

Re: Ice Build up??
Thanks for the update.
There will be a delay due to pumpdown of the remote system before the compressor starts and then a further delay for the coil to freeze down before the evaporator fan starts... its all good.

Re: Ice Build up??
Thanks a lot for everything Gary. I really appreciate it. You called it from the beginning.
I didnt touch anything with that solenoid valve on the refrigerant line or the thrmostat thats wired into. The way it is now is the Hot wire is going to the thermostat the and the neutral off the termostat is connected to the solenoid. The second wire to the solenoid is hooked up to the neutral. Does this sound right to you?? Everyhting is running and its holding temp....but with this freezer you never know.
I am actually thinking of taking a course on refrigeration here. It pays for itself....there are way too many clowns in NYC. I found so many misplaced wires on this freezer its a shocker it even worked.
This is such a relief to see it work. It's been messed up for about 10 years.
Thanks again!
Jack

Re: Ice Build up??
Greetings,
happy V'day to all of you. I need similar help Jack
needed some. I read all the threads by jack and Gary very carefully. I just defrosted Hill coffin case in my store. We have total 4 caes back to back.
all four them had ice build up and after defrosting with water (normal drill with our freezers, probably by virtue of some professionals not paying attention.)
We are able to defrost our freezers by advancing timers, so I think our freezers are on time defrost only.
I cleaned the freezer and before I put it back I checked and found that none of the coils (defrost) coils are heating up. DRain heater is working. I checked the fuses they are all good. Usually I can advance the timer and turn the defrost on. But defrost heater is not turning on.
all the the defrost elements appears to withdraw the current checked with hook kind voltmeter.
fans are running in the case. Our case fans runs when it defrosts. our case fans runs all the time to my knowledge. Any clue why defrost heater would not kick in. It is important to mention that there is no ice, as i cleaned it and freezer is at room temp. Historically I was able to turn the defrost heater by advancing the timer.
thanks to all of you for being community,
shan

Re: Ice Build up??
Hey Shan,
I'm no refrigeration tech but I learned quite a bit from the great people on here and from talking to techs at Traulsen. Where does your ice build up ?? on the coil or in the walls of the box?? Maybe your heaters just went bad ? Also, why are the fans running while it is in defrost?

Re: Ice Build up??
this was a funny thread. left hand doesn't know what the right hand is doing. solenoid ... was installed when the unit was remoted and the guy remembers 'cause he paid for it, Garry was talking about the clock's selenoid...ohh well, I just saw the fun in it. Good Luck Dude, or ... mind your donuts

Re: Ice Build up??
could have a leak also check thermostat if you dont have a defrost mechanism then the thermostat could be acting as that by cutting the compressor off and on. if its not working properly the thermostat might not be shutting the compressor off causing the system to constantly run and freeze the coil

Re: Ice Build up??
Is the freezer actually level? I didn't see any mention of this in the threads but I have seen a problem with icing on the blades, etc. due to the freezer tilting too much towards the front. Just something to check.
