The thermostat should show open above 50 degrees to protect the refrigerator from over heating during defrost. If its not closing while frozen the thermostat needs to be replaced and that will get you going. The new thermostat come with crimp splicer connections and you only need to unplug the fridge and cut the two wires to it, then splice the new one in.
If that don't get you running again let me know and I will give some other things to check, Thanks, Sea Breeze

I have a Fisher and Paykel fridge E521T. It is about 10 years old. The green light was flashing and it wasn't freezing as well as it should, so I pulled the back from the freezer compartment and it...


First a note: the defrost system (fan and element) are not on all the time. The defrost fan usually comes on once every several hours (8 hours in F&P fridges with defrost control).

The problem is usually the defrost thermostat. The thermostat is installed in line with the fan and heater element. If the thermostat is faulty the fan and element will not get any power.

The thermostat can be tested using a multimeter. If reading impedance across the two thermostat's contacts the multimeter stays on infinity, then the thermostat is open and must be replaced. A different kind of test is made jumping the thermostat. If the fan and element work with thermostat removed and contact jumped, then the thermostat has gone.

Not freezing wont get down to temparature, stuff has defrosted, makes whooshing noise when dooor opended and light flashes. Its googsed Whirlpool ARC4030UK


If there is whooshing noise, check first the damper fan. See if the fan is broken or if fan duct is obstructed. Check the fan in the evaporator system (defrost system) behind the fridge's firewall.

The problem is commonly the defrost system. Fan or thermostat do not work. As result the coils freeze up. With coils frozen the condenser will go under stress and will loose efficiency. The effect is the system not producing enough cold.

The defrost system comprises defrost thermostat, heater, defrost control and fan. The parts that fail more commonly are thermostat and heater. Both parts are located behind freezer firewall and tested reading impedance with a multimeter. Element and thermostat are faulty if they return Ohms infinity (the circuit is open) when reading impedance with a multimeter at the part's contact.

If thermostat and element are OK, the next part to be tested is the fan. Fan can be tested by simply checking that the motor is running when energized.

Here a tip explaining how to deal with defrost problems on a different fridge model: Fridge not cooling. Procedure is similar with your model.

If defrost system is not the culprit, check if the compressor is starting and working properly. If compressor is not starting properly replace the relay and capacitor kit connected to the compressor motor. Compressor motor has long warranty. If the motor itself is defective call the manufacturer to check warranty terms.

If compressor motor and starter kit are OK, defrost system is OK (including defrost control) it can be a refrigerant leak resulting in low gas pressure in lines. In that case the compressor motor will stay on most of the time.

The most common faults resulting in no heat are due to defrost system problems or to defective compressor motor starter kit.

Refrigerator temperature too low freeezer temterature ok


Thank you for contacting

Check the condenser under the refrigerator is clogged with lint. Make sure that the condenser fan underneath the fridge is running properly. You can get to it through the back. Check the coils on the rear of the refrigerator and make sure they are clean and dust free. Also check the back wall or floor of the freezer section for frost. Check the evaporator fan to see if it is running. Check the condenser coils under the unit for blockage from dust. Check the condenser fan under the unit to see if it is running. If you have frost in the freezer there is a problem with the defrost system and the freezer will start to warm eventually as well as the fresh food section. If that is the problem you can check the defrost thermostat, defrost heater/s, and the defrost timer or adaptive defrost control If used on your unit or the main control board if so equipped. Also check the freezer to ensure it isn't over loaded with food stuff, reason being air must flow freely threw out the entire refrigerator in order for the thermostat to work correctly.

Ice build up in refrigerator. Not cooling

Fault in the auto defrost section. shut off the fridge and defrost , check onthe thermostat , faulty lines wire breaks due to frost. if not trace the wires to the auto defrost timer. check the heater continuity/resistance. When the fridge is started back check the timer and see if the auto defrost works. If not check thermostat and the timerr contacts or if it is running. if not replace.

Freezer works o.k.,but fridge does not get very cold

There should be a defrost heater that that takes care of this if it is supposed to be "frost free"- but obviously this isn't working properly. It could be the heater, thermistor (thermostat) or the control.
Just check that the door seals are still ok and not split, as this can cause excessive build up of ice.

Warm fridge cold freezer

Hi,advance thermostat setting, to get colder , it's possible you got defrost problem, is there excessive ice building inside back of freezer? to determine if you have a defrost problem, unplug ref. for about an hour,let it defrost, let all ice melt away, it's better to remove your produce, keep doors open to speed up defrosting, after defrosting and cleaning plug back your ref, and let it work for another hour, and check result, if it's o/k, put back your produce, let me know, during hot summer months, regular use (opening) of ref, could cause excessive ice build-up evap. if after defrosting and cleaning ref. work good for 3 to 4 days, but start doing the same thing, let me know, it means you got a defrost problem. also check your thermostat, but first defrost and clean it, that could just be your problem. good luck.

Refridgerator not cooling off, but freezer is working. Fridge is only 3 years old.

check to see if fan is running in the freezer, if not replace fan. this is the usual problem, however may be more than that. you may have a defrost issue, by removing the back cover in the freezer side you can tell if the coils look like a block of ice or not.(not supposed to). if so check defrost components, defrost heater, defrost thermostat, and defrost timer.

it is more likely to be the thermostat, it is very common on fridge freezers which only have 1 compresser. thermostat should be no more than 10-12 pounds from a spares outlet. they do universal stats so it would worth trying at that price. hope this helps
