How do I fix a Fisher and Paykel refrigerator Model E442BRE showing fault code 64 and gets too cold in fresh food compartment ?

I have a Fisher and Paykel E442B upside down, which is a very similar model, and I just fixed the same problem (temperature was around -4C even though I set the fridge temperature as warm as possible).

The cause of my problem was excessive ice build up on the side of the evaporator coil (which is in the back of the freezer compartment behind the rear plastic panel). I had the same problem around a year or so ago, so I expect it to be a regular occurence. To defrost the coil, I removed all the drawers in the freezer, and the plastic insert by pulling out the bottom of the panel out and rotating it upwards until it released at the top. There are a couple of snap-in tabs holding the panel in, so with a bit of pulling they released. The tabs are either side of the slot at the bottom of the panel.


I then supported the panel horizontally on the top shelf so that I didn't have to disconnect the thermostat wire and the circulating fan wire.
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.

I'm not sure why the ice build up on the side caused the problem, but presumably it interferes with the proper flow of cold air to the fridge compartment.

If you don't seem to have ice build up like I did, then it could be a thermostat problem, or a fan problem (a symptom of which would be fridge being colder at the bottom than at the top).

You're frozen up.  Defrost completely.  Then, clean your condenser.  Make sure to never leave open containers in the fridge...water condenses into ice.  If you still have problems, you may be low on gas.

The problem is the refrigeration evaporator, located in the freezer section is blocked with frost and ice and not air can pass through it. Four different failed parts can cause this problem. The defrost timer, the defrost heater safety thermostat, the defrost heater, or the evaporator fan motor. Unless you are very good with a volt-ohm meter, it wiil be difficult to distinguish which one of these parts has failed. A qualifed refrigeration service tech or a good appliance service tech with a refrigeration certification can find this quickly.

first of all, check to make sure your fan is working, also check the inside compartment for the damper should be open when your rise or lower the temperature settings on your dial. when you rise your temperature dial to 5 you should feel air flow coming out of the damper, if not check to make sure that the evaporator fan is working first, if it is than check the damper door should be open sometime this damper door gets stuck on something or they break off.
