Candy frige freezer, back of outside pipe gets frost

[admin]

Hello… everyone

I posted about water leaking problem of Candy,CPCA240FFK No.3400013 0309 0603A Approvaltype CF24, which we’ve got as a second hand.

The water leaking was from the thick frost on the pipe, which is connected to compressor, copper colored. The frost coveres the pipe and joint part of compressor.
The second hand shop person came to fix the problem….
he said… that it is “over gased” … and let some gas out from the other pipe of compressor.
BUT…. 😯
The frost got worse after that…. 🙁 now… much thicker than before, the frost is not able to remove easy…. so thick.
When the fridge becomes quiet… the frost melts and make paddle on the kitchen floor.
when i touch on the pipe(when it is not frozen), i can hear… a bit of noise… it sound like a sound when i touch on TV screen.

I’m really concerned if i can really trust the person or not…

if… somebody can tell me what should i do…..
please let me know…

Many Thanks
Mrs.R

p.s.
the shop person said that the back pipe should get freeze (or frost).
Is it true? The fridge doesn’t have any tray under the pipe….

Re: Candy frige freezer, back of outside pipe gets frost

hi

the most probable cause of this is due to the refrigerant being over-charged. (too much gas )

this will cause the suction line to freeze and when the fridge reaches temprature the frost willmelt causing the water.

it may also be that the thermostat is faulty and not switching the appliance off.

i would suspect the first to be the correct one though,the refrigerant will need to be reduced else the life of the appliance is effected.

the appliance should also normally have a drip tray above the compressor.

Hello.. Bryan,

Thank you for your prompt reply. 🙂

The shop person left small wrench for open the gas pipe to let the gas out…. but I’m scared to do it by myself… 🙁

Can I leave the fridge in this situation, keep getting frost on the pipe?
Is it dangerous to leave like that?

Although I always have to keep eye on the fridge and plastic tray which i put under the freezed pipe…. I do not want to make the fridge life shorten…

Regards,
Mrs.R

They did what? That’s well dodgy, even as a second hand sale it should be SAFE!

There is no way that an untrained member of the public should be expected to do that. I’d get back onto them, PDQ.

The overgassed diagnosis is usually correct, unless the compressor is running weak. That will cause the appliance to run for too long a period, and in some cases the internal valves do not close 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}. This will lead to a high pressure on the low pressure side of the system, and in extreme cases a slug of ice on the return pipe.

One question though. Why is it overgassed? If from new, this would have been sorted some time ago, if it has been regassed there may be a reason for the regas. Regassing is only required if the system has been broken or a new compressor fitted. Some pople think it is like a car regards an oil change, and needs gassing every now and then. No they don’t. The gas does not deteriorate.

I’m bothered about his remedy of bleeding off the gas though. Take a look at the rating plate inside the product where you found all those numbers. Is there one that says R12 or R134A. If R12 he has done a naughty, if R134A still bad practice, unless of course he used a recovery station.

Don’t try letting any gas out yourself, you could actually attempt this when the system is pulling a vacuum, and let air into the system. That could write it off.

Suggest you ask them to return and get it sorted. If they won’t oblige, get a second opinion.

I daresay the poor guy sold you this in good faith. Refrigeration products in a second hand market is always very dubious.

Best of luck.

hi

well the short answer to your question is NO you cant carry out the repair yourself as what they have asked you to do is ILLEGAL.

the refrigerant MUST be recovered correctly.

as for the drip tray the correct one should be fitted so as not to allow water to run onto the electrical connections on the compressor.

If the shop refuses to carry out the repair correctly then a visit to trading standards and the councild enviromental dept would be in order as they have requested that you vent refrigerant into the atmosphere (spelt something like that ).

Re: Candy frige freezer, back of outside pipe gets frost

Thank you for your reply… kwatt, Bryan and Alex 🙂

Soon after i posted my last message, I called to the shop to let them know the problem is getting worse……. then………….. the shop person shouted at me … “leave it a couple of days! it is happning cause you’re keep pulling it out! ” (of course i didn’t… and told to the person i did NOT keep pulling out the fridge) …. 😯 😥 😥

well…………..
Even the problem is still there…. I feel much better after I read your replys… then… i know i wasn’t wrong … such a thing should not be happened even second hand. Thank you for your reply 🙂
I wish… i could have known second hand one is so much dubious. 🙁

Alex, answer for your question….
*i suppose the shop guy regassed (the fridge is second hand)…….
*as i checked inside of the fridge and the number is … R660a 38g
He has shop near us….. and selling whitegoods …. mainly second hand.

Bryan, thank you for your reply again…
the drip tray for now…. i put little plastic tray under the pipe, not to touch to compressor.

best regards,
Mrs.R

Re: Candy frige freezer, back of outside pipe gets frost

hi

for your own saftey (can never spell that word ) DO NOT let the refrigerant out !!

R600a is a highly flammable refrigerant if it is not handled correctly,if the appliance has been recharged with R600a then it will be massivelly overcharged as to get frostback on the suction line on this refrigerant it os overcharged.

also leaving a linetap on this refrigerant is a definete NO as it will leak over a short period of time.

opps did’nt realise using tina’s computer

Re: Candy frige freezer, back of outside pipe gets frost

hi bryan…

I won’t let the refrigerant out!… .
and… i will keep Mr.R away from it… 😛 thank you for your information.

sowwy… but does it mean…. the pipe( or line?) should not have tap to let the refrigerant out…??? The other pipe , opposite of the frozen pipe, has a tap on the middle of it…………………… is it dodgy another job of the second hand shop person………??

Re: Candy frige freezer, back of outside pipe gets frost

p.s.
as i turned the power control dial (?), which is on top of front side, from 2 to 1 … the frost seems less than before.

[kwatt]

Highly flammable = potentially explosive!

A line tap valve is most likely the bit that the shop has asked that you let gas off from.

R600a is also an exact science, not like the old refrigerant gases where you had a little leeway, the charge has to be specifically measured and you just can’t let some off.

Seriously, this is dangerous, Brandt (IIRC) had an issue with these types of units and one lifted a conservatory off it’s foundations when it blew.

The control will be for the temperature, 0 being off usually (on most Candy machines) 9 being the highest degree of cooling.

Be safe!

hello… kwatt

Thank you for your information!
I will never ever touch to the line tap!!!!

ow my god …………………….. 😯
Is it happened when they try to let the gas out? or………………….
is it happened while they are using the fridge normally…..?

Should i turn the fridge of immidiately…????

Re: Candy frige freezer, back of outside pipe gets frost

Now it is becoming clear to me. It is barely possible to just let R600 bleed out of a system, it does not run under a pressure like other refrigerants. Therefore it is a bit weird this guy was able to perform that operation. Let alone suggest you were able to.

This is only a theory, but I bet the compressor has been replaced with a NON R600 type, and it has been filled with a blended HC-FC refrigerant. Hence the fact it can run at a pressure, and it is possible to remove excess. This will also explain why there is too much refrigerant, and moreover explain why you do not have a plastic drip tray on top of the compressor. A non-genuine type compressor has been fitted.

Suspect you may have been sold a pup. To prove it out, take a look at the compressor, the black motor thing at the back which gets hot on the base. See if there are any numbers, in particular relating to the type of Refrigerant. If in doubt, give us all the numbers.

If this theory can be proved, then you have a case.

Re: Candy frige freezer, back of outside pipe gets frost

Hello Mrs R.

please do not release any of the refrigerant and contact the dealer you got it from and Point him to this site.

dont be to alarmed that the fridge is overcharged, but please get it checked ASAP and make sure refrigerant is reclaimed and not allowed to mix with air as that is when he explosive problems are an issue.

help and advise is allways avialable on the site.

cheers bob.
