Re: Samsung SR-S2028CSS on the blink

So tried a new evaporator cover – disappointed to see the evaporator is still freezing up after replacing the defrost sensor/fuse and heater element.

New cover is on and it’s working[ after seeing off the ice monster].
I’m not confident however that this will solve the problem.

Anyone have any further suggestions? Could it be an electronic control problem?

Re: Samsung SR-S2028CSS on the blink

Is the defrost heater the front part of the evaporator?

Anyway – it’s still on the blink.:cry: It behaved for quite a while after replacing the sensor/fuse and defrost heater element but it still heats up. I’ve got a temperature probe inside & the temp rises periodically – even though the temp shown on the display remains at 3c. If I turn the power on & off it recognizes the temp[and shows it on the display] and starts the cooling cycle again.

Will replacing the evaporator cover help any? I thought that just housed the fan.

Seriously thinking about replacing rather than spending any more time/effort/cash. It will be taken out the back and given both barrels….

Hi r600a

I’m confused now.

Evaporator Defrost element.
Thermal fuse
Defrost sensor

What am I missing?

Re: Samsung SR-S2028CSS on the blink

Replaced the thermal fuse and defrost sensor – fun way to spend friday evening!
Turned it back on and it appears to be holding the required temperature but will monitor over the next few days as the defrost heater may need replacing too.

Defrost heater: the one on the evaporator looks quite different to the one you can buy in [e.g.]partmaster. They look like foil heaters – does anyone know if they are easy to fit & whether the old heater is difficult to get off?

If anyone is in a similar position I can categorically say that replacing the sensors is not that difficult. If you are handy with a screwdriver & like taking things apart it’s a doddle. Just wish I’d read UKWhitegoods before I spent £85 on a useless Samsung-approved engineer who couldn’t suggest anything other than replacing the compressor. You would have thought they would be up to speed on common problems?

Here’s how:

1. turn the fridge off. Empty it & take out the shelves.
2. take the white screw out of the top of the light strip. pull the strip off – it’s held in place with tabs so I stuck a blunt knife down the tab to un locate them. may have to give it a good pull.
3. take off the temperature sensor outer ring by twisting it to the left. unscrew the purple cover. pull out the plugs behind it.
Take out the 3 screws holding the lighting board in place – pull it out.

you now have the evaporator cover in front of you, the top has two holes in it and there may be some polystyrene visible.

4. if you have a cooler element – like a plastic radiator on the bottom of the evaporator, take the two screws out & lay it on the floor of the fridge out of the way.

5. There are 4 screws holding the evaporator cover on, the top two are behind some pop off covers. the bottom ones are at ground level.
Take the screws out.
I found pulling the evaporator cover off quite tricky as it’s difficult to gauge how hard to pull. You may have an ice monster behind the cover so it could be stuck on. I accidentally ripped a bit of the cover off[it’s polystyrene behind the plastic front] as it was frozen onto the back of the fridge. If you pull from the top & wait, pull a bit more & wait, any bits stuck on will have a chance to unstick if they thaw a bit.

6. This reveals the bits we’re after. Mine was well iced up so I [carefully] scraped off as much as I could and then got a hairdryer on it. It did the trick & took 10 mins or so to clear of ice. You can pull the evaporator forward to get ice off the back as it’s held in place on two plastic clips.

7. The thermal fuse is behind the evaporator bottom left, top plug. the defrost sensor is in a white clip on the incoming evaporator pipe, top left, bottom plug.
I cut off all the cable ties. It’s straightforward to un plug and replace both sensors. The only cable tie I replaced was to hold the thermal fuse behind the evaporator away from the defrost heater. You can pull the evaporator away a little to make this easier.

8. Job done. I gave it a good wipe down & put it back together.

Took me just over an hour.

The parts I used came with useful instructions and cost just over £20.
If I have to replace the heater this is going to set me back about another £20.

Re: Samsung SR-S2028CSS on the blink

OK. got the bits. screwdriver at the ready.

I’ll post back how it goes….I’m going in…..
..smoke me a kipper…:salute:

Re: Samsung SR-S2028CSS on the blink

Thanks for the feedback.

Looking at the exploded schematic, is the defrost heater the thing that clips onto the bottom of the evaporator assembly?

As for changing the sensors the schematic has a defrost sensor DA32 10109N and a freezer sensor DA32 10105H do you mean these?
What about the thermal fuse DA47 10148J?

Chezza – where can I get a heater on its own?

Re: Samsung SR-S2028CSS on the blink

helo_75 – thanks.
Are these symptoms what you would expect with this fault?

Presumably this is the one you mean
DA96-00013B – Samsung Fridge Freezer Evaporator & Defrost Heater

Is it something easily replaceable?
Or if not would a fridge technician be able to do it if I supplied the part?
