Can you explaine a but more about the fault you have as im not sure what you mean by evaporation tray failure. Whats it doing wrong for you?
Arr im with you now.
Yes that try does remove. Its just clipped onto the top of the compressor. So to remove it you need to hold the tray with both hands and then pull it forwards and at the same time wiggle it from side to side to release it from the clip.
9 times out of 10 it comes off fine. But the odd time it can break the clip. All you need to do if this happens is get some slicon sealent and use that to stick the tray to the compressor as that will work just fine as thats what i do if the clip breaks.
Thats the only way you can remove the tray as the clip is under the tray so you cannot access this. So do the above and you will be able to remove the tray and give it a good clean out as they do gunge up over time on these.
If you need anymore info just get back to me.
I see the question is still open, Is there anything else i can help you with on this?
If not then if you could remember to rate the answer that would be great.
