- unplug the refrigerator

- move ice crem into the refrigerator section
- remove all shelves and the bottom tray.
- remove light bulb cover and the bulb
- unscrew two 1/8" screws on top corners of the ... Read more back panel
- unclip the ground clip on top
- pull the back panel up; pull the left side toward yourself
- test 3 thermistors (see instructions below)
- test the thermostat (see instructions below)
- if either thermistors or the thermostat units are defective, they may be the reason for fan malfunction, not the fan itself.
- unscrew 2 philips screws on either side of the defrost heater
- pull it out and unplug the 2 wires on either end. Replace with a new part.
- putting together is the reverse of disassembly
- move ice cream back to the freezer
--- thermistor testing
- unplug the refrigerator
- locate thermistors to be tested. There's one on evaporating coils, one on bot. left of the freezer (behind deep tray, with white wires), 1 in fridge section (top left, in the corner, inside square white wire conduit; undo the top 1/8" screw ONLY and pull conduit up).
- without disconnecting from the circuit, place a thermistor in a cup of ice water. Wait for 5 minutes
- locate the main control board. Locate and unplug the J1 connector. The pinout, starting from the side with all wires connected:
* pin 5: ground
* pin 4: evaporator thermistor
* pin 3: freezer
* pins 2,1: fresh food thermistor
- use an ohmmeter to measure resistance. Push the needle of the ohmmeter into the socket, where the wire plugs in, without trying to remove the wire. It should be 16.3 kOhm +/- 5% (for 0 deg C)
to replace a thermistor
- cut out the old thermistor, leaving as much wire as possible
- strip the wires, twist them pairwise
- use a bell connector filled with RTV silicone, to ensure that no moisture can get to the connection
* others have also used butt splices and screw-on caps with electrical tape (for moisture isolation)
- using a proper crimping tool, squeeze the bell connector to secure the wire
------------- thermostat testing ---------------------------------
- it's a round quarter-sized cylinder w/ pink and orange wires
- check for bulging (= burnt)
- locate temperature ratings on the side of the thermostat. It should read e.g. 140-30F. This means it's switches to open circuit when >140F is reached and switches to closed circuit when <30F is reached.
- unplue the 6 pin connector that has thermostat.
- test the thermostat. Orange wire is in the 6-pin connector; pink wire can be disconnected from the defrost heater under the evaporation coil. It should read closed circuit (no R).
- place the thermostat into a cup of boiling water. It should open.
- if OK, reattach the thermostat
