Freezer

Post by Herrie »

My ZERO 80l Freezer has decided to stop working after our Kgalagadi trip.

The indicator light indicates that the differential pressure is to high. The guidelines tells you to switch it of for 5 minute and then reconnect - does not want to work.

Anything else I can try? It has a Danfus compressor.

Hi Herrie,

I have had similar problems with my National Luna 80L Fridge (which also uses the danfors compressor) - although mine did not stop working but it just stopped cooling at all and stayed at room temperature. This happened for the 1st time in the middle of the Richtersveld last Dec in 40 deg plus day temperatures! :surprised:

Long story short - a bloke told me sometimes the fridges gets an airlock from all the shaking and then don't want to cool. He told me to turn the fridge on its lid - take the cover around the compressor off and let a little bit of gas out by the filling tip.( National Luna fridges has a filling tip similar to a car tyre pressure valve). I did this and let some gas out - or at least it was actaully more air than gas that came out - and until the gas came out ( I am talking short bursts of 1 - 2 seconds 3 or 4 times) - turned the fridge around and Bob's your uncle it was working again!! :thumbup:

My fridge did it again some month ago - followed the same routine and bob's your uncle it is going strong again!! I took it the other day to have the gas level checked and it is still fine - no need to refill yet.

I must stress that this process must be done fairly quickly - within a couple of minutes - because if the fridge is left too long on it's lid the oil from the compressor could run into the gas piping - which is not good. But have done it twice and on both occasions sorted my problem and got the fridge working again.

However I don't know if the Zero fridges also has the car valve type fitting - mine is situated near the compressor.

Hope this helps!!

Nie meer as 5 min in totaal nie - ek dink die "geheim" is nie in die onderste bo los so seer nie maar wel die gas of lug wat uitgelaat word - jy sal sommer sien dit wat eerste uitkom is borrelrig. Ek laat so +- 30 sek verby gaan tussen elke burst - so 3-4 vinnige bursts (1-2 sek nie meer as 3 sek nie) en as dit jou probleem is behoort dit opgelos te wees.

Het jou yskas heeltemal ophou werk of net ophou koud maak?? - maw die yskas sit aan en die kompressor skop in maar maak nie fisies koud nie. Dis wat myne gedoen het - en bogenoemde is wat my probleem uitgesorteer het.

Moet by se my swaer se yskas (hy het n kellerman) het dit ook gedoen - syne wou ook niks weet van koud maak nie en die gas uitlaat oefening het ook nie op syne gewerk nie - en op die ou end was dit sy kompressor wat opgepak het.

Laat weet maar of jy die stryd gewen het.

Drie flikkers is high pressure, en dis net wat dit beteken. Die kompressor motor kan nie aanskakel nie a.g.v hoe druk stroom af vanaf die kompressor. Minder gereeld 'n blokasie in die pencil drier(15%-20%) Gewoonlik die kompressor wat moeg is. Kan ook sy black bocks wees. Die simtome kry jy as jy erge skudpad ry en daar is erens 'n swak konneksie (bv. hella plug of fuses) wat die kompressor aan en af laat sit. VOORBEELD. Jy ry nou 'n skudpad vir 'n een uur en die kompressor skakel 10 keer aan en af per minuut en siedaar die kompressor brand uit of die block box groet. Het al heel paar kompressors vervang nadat mense die Kalahari Gemsbok park besoek het.
Die uitlaat van gas sal die werking van die yskas sleg beinvloed. Pieter jy sal nog so, bv. 5-10 keer die gas uitlaat vir 3-5 sekondes en jou kas sal nie -5 grade haal nie. Dit boere raad werk nou maar daar is fout en soek eerder die regte fout.
Vuur warm groete.

Ek hoor wat jy se Vaatjie maar ek het darem nog geen negatiewe werking van die yskas ervaar nie. Ek het hom ook nou die dag ingevat net om my gas te laat replace of optop - maar die yskas mense se daar skort nog niks. Ek gebruik my yskas voortdurend in die huis ook sommer as n small drinks yskas - en hy loop nog punt in die wind sover. Maar ek stem saam met jou - jy kan net soveel gas uitlaat tot op n punt dan sal dit beslis die yskas se werking negatief beinvloed. Dankie elkgeval vir die waarskuwing ook.

Die kompressor het opgepak en ons kry nie 'n ander een nie! die een plek wat ons miskien kan help het 86 op back-order en hulle vra tans R3200-00 sonder VAT.

Waar kan ek 'n kompressor kry?

Herrie,......Engel vrieskas hier kom ons!!! Ek is nie die aardbol se grootste Aussie fan nie, maar hulle kan maar 'n kamp vrieskas bou.

Net vir die aardigheid: Ek't by geleentheid gehoor van Hiena se kind wat 'n engel 40L uit 'n kampplek gesteel het deur met hom in die hoog-voor in sy bek die bosse in te verdwyn. Na 'n redelike lang soektog waarin verskeie mense moes help het hulle die verwoesde engel in die bos gekry. Hy kon nie toemaak nie en het gelyk of hy in 'n taxi geweld geveg was, maar hy het nog geloop....en die Aussies het nie eers Hienas nie!!
Patrol fan!
