Have they cleaned the drain tube that runs down the back of the fridge? If not and the tube is clogged water will back up and give you the problem that you are having. The only other thing that I can think of, is that the defrost cycle may not be set to a minimum amount of time to where this can be increased to allow the freezer not to let the ice build up.

trn your thermostat right down see if that helps

Very possible the door was accidently left open for a period of time. When that happens, moisture latches on to different areas which inturn creates ice build up. In short, do a good defrost and then restart freezer again.
Testimonial: "Thank you. Freezer defrosted and working again!"

SOURCE: Hi, I have a fisher
open the doors feel around where the seals close on the frame of the unit do you feel its hot sometimes what happens is when the compressor fan stops running this is one of the first ways of telling also as far as the ice you would need to do continuity test on the tstat heater to assure that they are working properly and advancing your unit into defrost mode when its supposed to be ingore the first comment i just saw that you said fridge feels warm that would be on the inside which would be a defrost problem remove the back panel of the freezer you should either see the fan not working and blocked up with ice which causes the fridge to get warm or either your tstat or heater have went bad if you are the one conducting the continuity test please unplug your unit before testing if you have any further questions please message me back and please remember to rank how this opinion has helped with your appliance situation Thanks again

SOURCE: Hi, I have a Fisher and Paykel E402B
Your automatic defrosting circuit is not working. There are several components that can stop the defrosting process:
1. The defrost control
2. The defrost element
3. The defrost thermostat
Any one of the 3 can open cause the automatic defrosting process NOT to work.
If the defrost control fails, it just stops defrosting and ice builds up on the evaporator coils.
If the defrost element fails it will go into the defrost cycle and not cool again until the internal temps reach 60 Deg F.
If the defrost thermostat fails in the open position the heater will not heat up and the freezer will ice up.
There are 6 models of the R402B so I was not able to narrow down a source your exact parts data.
However, if the defrost control has failed the good news is the most expensive one is $18.95 AUD
Hopefully this gives you something to go on. I think it will either be the defrost control or the thermostat. If you can locate the defrost control turn it until it clicks ONCE and see if the unit shuts off and completes a defrost cycle. If it heats up but does not complete the defrost cycle again your looking at a problem with the defrost thermostat. If it does not heat at all then the problem is the heating element.
The defrost control will have 2 sloped tabs on it so that you can only turn the control one direction. The defrost control dial with the tabs will be no larger than 1/2 inch in diameter.

You most likely will have to make a "contact" enquiry at either site above. For the defrost tmer, heating element or the defrost thermostat.

With a small fan heater set on low, aimed roughly at the ice buildup on the left hand side of the evaporator coil, I defrosted the ice built up. This took around 2 hours or so. Then put it all back together and it worked fine. 2,119 views
