fridge warm freezer cold?

[babsnsarah]

Hello.
Sorry if this sounds daft, my fridge freezer has a problem. Fridge is warm but freezer is -20c. Thermostat operates ok( compressor starts + stops). Is this an easy replacement of fridge t/stat or should i be looking at more indepth problems. Evap in fridge cool but not cold + stays around +12c.
I normally work in transport refrigeration so im at a bit of a loss. Any help appreciated. :confused:

is this a fridge with two compressors?

is it a nonfrost?

some more information is needed.

Hi Babsnsarah,
As Chemi says, we need a lot more info. Make & model might help, no of comps, gas, any evap fans ?.

By the way, if you are a transport engineer check out the "mobile" section.
Are you from a TK or Carrier backround or like most of us done both.

Regards

Hi there

I am not a domestic engineer but did a domestic course about 4 years ago ,from what I can remember your fridge freezer operates of one stat.
Your freezer relys on your fridge section operating the compressor.A problem a lot of people have is when they put there f/freezer in the garage over winter the fridge never rises above 5C so the freezer does not operate and rises to the same temp as fridge.

So I would guess your T-Stat is out of calibration and operating around 12C instead of 5C.
N.R.S do an equivilant stat I thinks Its a VL9 but check with them

sorry should have thought of more info required.#

Hi Babsnsarah,
There are quite a few jobs in the jobs database. Which area of the UK are you in and maybe we can give you a lead.
What sort of area are you looking to go into. Industrial (ammonia), Commercial (Supermaket type).

thanks Tony T

hi tony,

one more question, do you have one thermostat for frige/freezer or is it two, one for each.

R134a tends to block cap tubes and filters. try to feel the pipes at the back for abnormal temp.

basicly, most of the pipe work is inside the walls so its impossible to check there.

by the way, indesit is the twin brother of ariston, bouth names of one italian manufacturer.

how does it defrost automatic if no evaporator fan and heater exist?

let me know what you've found.

Most refrigerators I’ve seen have an evaporator fan check the defrost system for proper operation.

Greetings All! (from across the pond)
Babs, I can offer a suggestion. It sounds like you have a plugged defrost drain line. This is where the water goes to in the bottom of your freezer when it goes through the defrost (removal of ice from the freezer coil) cycle. It sounds like that hole is plugged and now the water/ice has now frozen in the vent that lets air circulate down into your refrigerator compartment. What I usually do in this case is to unplug the refrigerator, empty out the freezer compartment. Usually I also end up either pulling off the back panel or the bottom panel (in the freezer compartment) Looking for that defrost drain hole and thawing it out with a heat gun (be careful of melting plastic) or actually I use a hair dryer. I can sometimes do this also by pouring small amounts of HOT tap water onto it and then sopping/absorbing it away with a sponge or dishcloth. I repeat this until I get the water to go down the drain tube. I hope this help everyone. I also go to a forum called www.hvac-talk.com. So along with this site and the other I think I'll come across a lot of expertise to help me in my daily toils. LOL. I look forward to chatting with everyone. Let's see if we can learn from each other.

This type of F/Freezer operates on 1 thermostat that senses the evaporator temp in the fridge / high temp section, if the F/Freezer is short of gas the freezer will still reach its correct operating temp but the fridge section will not cool, check to see if the compressor is running permanently, if it is then i would suggest you recover the gas, weigh it and re-charge to the correct amount that should be printed on the manufacturers label. :)

:cool: trying to be more positive! Sounds like a moist cold ref manual defrost freezer, humidy plate evap in p/c. These quite often have an off cycle heater which is in parallel with t/stat uses comp. windings for return. It is sometimes wrapped around plate edge or behind plate , if it is open circuit it will cause too long off cycles. If plate is not frosting at all while comp is running it sounds like restriction or S.O.G. unfortuantly alot of pipe work is often inside walls and inacessible. If it has hot gas mullion heating this is a commen leak point as alot of manuf. use steel pipe and as some water gets into liner they rust out. they can be disconnected will slightly reduce cond. add extra if concerned also will cause cab. to sweat in humid conditions.

sounds like a bin job either way..

cheers

p.s it's short of gas....
