TFJ28PFDBAA General Electric Refrigerator - Instructions

Remove the one screw holding the unit in place, unplug it, slide in the replacement, plug and screw it in.

There are Great videos on YouTube!!! Turned off power,Removed trim ring, Pushed a philips head screwdriver in one of the holes underneath the electrical panel with the selector push buttons. This releases the electrical panel. There are Three wire sets with plugs. I removed the plugs and took the electrical panel out. Removed four Phillips head screws and pulled out the big paddle switch. This then exposes the flapper. Replaced flapper with new one and reassembled everything. When I had everything apart, I cleaned with window cleaner. It was pretty moldy from the water leaking. Turned power back on and tested everything to make sure I didn't mess anything up. Works great

Replaced dispenser door flapper by following the do it yourself video in this site. It was really easy. Just be careful when removing the dispenser black bezel. I broke one of the little tabs when taking it off.

------------- defrost heater replacement --------------------------
- unplug the refrigerator
- unload all shelves underneath ice maker
- 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 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

Part attaches to metal plate near crushing fingers which attaches to ice holding bin. Remove about 6 screws total on each side of plate. You must disassemble the auger & other parts so you can reassemble it in the proper order. Not many parts but i always take pics to cut down on time. New part is at the other end of the auger and acts as the holde of the auger shaft. Picture a crankshaft with a bearing on each end so the auger rotates between new part and the other end of auger shaft. That's it.

I removed the back panel of the freezer to troubleshoot and found the coils to be completely frosted over and the bottom of the freezer was a block of ice. The cold air was not allowed to circulate over to the refrigerator side. I put a meter on the defrost heater at the bottom (basically it's a wire filaments encased in a glass tube) and there was no continuity which meant it was bad. I also took the defrost sensor (small round sensor at the top above the coils) and put it in a working freezer then after awhile I took it out and put a meter on it until it warmed it up and it clicked so I knew that worked. The defrost sensor should show continuity (closed circuit) when cold and no continuity (open circuit) when warm.
So at this point I knew the problem was the defrost heater due to no continuity. I purchased the defrost heater assembly which also came with a new sensor. Unplug the old and plug in the new. Super simple. The defrost cycle works as it should and now the refrigerator works perfect.

I removed the plate covering the water valve for the ice maker and water dispenser, removed the nut holding the 5/16" tubing to the valve and took off the tubing and nut. I did not need to turn off the water supply or unplug the unit. I removed the kick panel in the bottom front of the refrigerator, replaced the existing plastic fitting with a new push-on fitting, then spliced the tubing coming from the water chiller to the valve where the leak was thus bypassing the broken tubing with new tubing. I reassembled the valve using the original plastic compression nut, replaced the cover and ran the water dispenser while checking for leaks. The water dispanser works great with no leaks.

Removed icemaker from freezer,
Removed 3 screws from cover plate, and removed screw securing main gear, removed gear.
Pulled back cover plate to expose switches and mechanism.
Removed screw holding switch to remove switch, and installed new switch.
I should have taken a pic of the cover plate, the interior mechanism and the wiring as I went along. It would have saved me 45 minutes in reassembly. Also, as luck would have it, I reversed the wiring on the switch. So off was on, and I had to remove it, switch wires and re-install.
But it works!

My husband took out the old icemaker in about 5 minutes. The new icemaker was a perfect fit even though the refrigerator was >10yrs old. The only difficult part was the plug extension that was needed so that it would fit into an older appliance. The part was included, it just made the cord about 3 inches longer than it needed to. After working with it for about 20 minutes we were able to fit it on the back side of the icemaker. Now it works great!!

Had to defrost the freezer to melt off all the ice before servicing. Once that was done the icemaker replacement only took about 15-30 minutes to complete. The new icemaker came with many accessories and adaptors that were not needed and the instructions were based on replacing an older model and not really clear for my model. They mentioned not being able to use the new stripper but it was exactly the same as the old one so I left the new one in place. All in all it was easy and did the job.

Opened, discovered not flapper but more complicated

Followed the online video. Unplugged refrigerator, removed trim piece, lifted control board cover, removed 4 screws retaining circuit control board and removed the 3 connectors from the control board. Located flapper and removed by using small flat tip to take tension off flapper connectors. Helper held flash light to illuminate flapper connectors. Reversed procedure. New flapper seals well and cured problems. Circuit board was a bit different than one in video, but still had the 3 connectors. Marked each connector with grease pencil at top edge to ensure correct reconnection. Should note how wires are threaded around circuit board to ensure they are tucked back in correctly in reassembly. Remove trim piece carefully. I broke 2 of the 8 plastic pins that hold trim on. May be due to age of unit as they were brittle. 6 pins still hold trim piece flush.

Remove the burned out bulb and install the new light bulb.

Concerned about removing and attaching front panel to broken drawer. Rep. said wasn't sure but most just snapped together. Rep. was correct. No tools required.

Screwed new bulb in socket
