The cooling unit is out - what now???

[davethebirdman]

Okay

now I have notcied that my other V-39. The one that I bought restored, which I fitted a new T-Stat to today also is running and cutting and running and cutting. Certianly not wth the five minutes needed between cycles.

The old T-Stat on this unit was bolted to the Evap fan housing. It as the same tip as the new T-Stat. Should I bolt it to the housing too instead of letting it hang under the bottle basket.

For the time being I have turned all the machines off, its like a Sauna in the room.

Plse see picture. Hoefully explains better than I can.

Okay

this is a picture of the inside of the Second V-39 that does nt have the bolt on thingy.

As you can see the sensor is just below the bottle drum and sort of hanging over the fan.

Glenn - I'm not quite sure what you would like me to try and attach the tip too. Is it to the fan coils from underneath??

Dave,

I think you need to try to make it so the probe is right next to the evap coils (within 1/8").  These coils are behind the shroud where the evap fan is.  The evap coils are what gets cold and that's what the stat needs to "feel".  With the probe next to the bottle basket, I don't think it will get cold enough to shut off the unit.

Hi Wayne

do I do that by going under or over the cover??

Thanks

Dave.

PS... I have checked Steve's online Cat and I definately appear to have the air sensing rather than bolt on one. I have un hooked the one I bolted to my restored machine and turned them off fr tonight.

Trying to get the kids to sleep at the moment. Mum is working very late. My 2 year old is being a right pain. How we love our off springs. We need that Paternal love otherwise they'd be sitting in the garage at the moment and its minus one out there. No problems cooling bottles in my garage.

Hi Dave,
Try what Glen and Wayne is suggesting to fasten the end of the cap tube to the metal on the fan schroud like the other machine of yours has. If you have one of those spring type clothes pins, you can use that to fasten the cap tube at differant locations to see if that might help.

Dave,

Whichever is easiest to do.  If you can go under, that may hide the tube a little better than going over the shroud.

I know all about kids sleeping habits.  They are wonderful, except at 2 am!

I'm getting very bored with this now. I want my life back, all i'm doing s going to bed and dreaming of bloody compressor units.

My restored machine, which was working fine before all this started now just completes the two minute cycles. On for two off for two. When I fitted the T-Stat on Friday it seemed to work okay and as it runs very quiet I left  it on cooling the bottles. It was only when Glenn mentioned the cut off safety switch that I really went back ad looked at it and noticed the two minute cycle, so it could have been running like this for a day and a night. Have I done some serious damage to this?'> It doesn't matter what I do with the tip of the T Stat clmap it re-position it it just runs the cycle and is very cold.

The new machine - I have clamped and re-positioned most of the morning. Where the compressor was running continuously previously it now goes into the cycle.

Is it time I looked for someone who knows what they are doing locally (If I can find someone)

I always manage to turn gold into copper. (Now feeling sorry for myself)

Everyone,

First, a question to Dave:  With you machines doing these 2 minute cycles, are you able to set the thermostat dial on something reasonable (like 2)?

Second, a question for the group: If Dave's answer is yes, should he adjust the cut out/cut in settings on the stats?

Dave,  if you do this, it only takes a very small screwdriver.  But, it's best to keep a record of the adjustment, so you can put the thermostat settings back to where they were when you started adjusting.  Basically, the cut out and cut in settings change the temperature difference when the compressor kicks on and off.  They are labeled on the side of the thermostat.

What does everyone think?

[davethebirdman]

Wayne

I have set them both to two. But I don't think that the T-Stat is cutting out because of the temp it has reached, more likely what Glenn said. The compessor is cutting out as a safety and then re-setting and going through it all over again.

I honesty can remember how long a cycle I had previously with the restored (my main concern) machine but it was most defiantely longer than the two minutes now.
