TFT27PRBGAA General Electric Refrigerator - Instructions

First I removed the electrical plug from the back of the freezer that plugs into the icemaker. I then removed the two hex head screws that hold the icemaker to the wall of the freezer and removed the icemaker. I removed the plastic cover, which incidentally protects the gears, by prying it off with a srewdriver. I removed three small nuts(7mm) which holds the internal cam in place. I removed the cam by pulling it off the shaft. Once I got the part from you folks I reversed the procedure that I just mentioned, and put the icemaker back together. It works great. The part with shipping was around $16.00. A new icemaker was roughly $159.00. If I would have called a technician it would have cost around $300.00 to repair.

I removed the ice maker,removed the broken piece of the old light shield,screwed the new light shield in place,and replaced the ice maker.It took all of 5 minutes.

Replaced flapper valve per website instructions. GE factory technician took two weeks to get here, charged over $100 for the call and told us we needed a new refrigerator door at a cost of over $500 to fix the problem. We sent him packing. After visiting the PartSelect website, the $5.88 PartSelect flapper valve fixed the problem. Amazing.

Unplugged refrigerator and turned off water valve at wall. Removed the entire back, lower cardboard panel (turns out I didn't have to do this...could have just removed the screws from the right side and folded the cardboard along a perforated line designed for that purpose). Removed screw holding water control valve to back of refrigerator. Took new control valve, and slipped on adaptors for electrical connectors (in bag) to the two smaller of the four electrical prongs). Removed electrical sockets from old connector and placed them over appropriate prongs on new connector. Unscrewed the two old water out lines, cut the old fittings off and slipped the lines snugly into the new outlet valve (new valve had slip on connectors not requiring lines to be screwed in). Keep straight which line goes to which outlet port! Then removed water line going into old fitting and screwed it on to new valve inlet fitting (after removing black plastic protective cap). Turned wall water valve on, checked for leaks (none), and plugged refrigerator back in. Water restored to both icemaker and water dispenser!

By the way, the first valve came damaged, but one phone call and the people at Part Select promptly sent out a replacement which I had the very next day (and this was two days before Christmas!). Great job!

Defrost heater turned black. Test showed infinite resistance. Problem went away after the heater was replaced.

I had made a dry run at the repair after watching the instructional film provided by part select and it seemed easy enough.
The only problem was that i needed to use the electrical cord extender (provided) to adapt to my plug type. That presented a problm because it needed to be tucked up out of the way to allow the ice bin to clear. Just needed to be creative in how you wrapped the cord behind the ice maker unit before snugging the attachment screws.
Cranking out ice like crazy.

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

The operation is very simple on this valve. I disconnected the water lines and wires.
Then two I removed the two screws attaching
valve to the ref.box.
The reinstall is just the opposite from removal.

I simply removed 6 screws that held bucket to face and pit on new bucket and put it back in freezer works great

------------- 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

Researched on internet/you tube; ordered part, and did the repair. Easy to do and saved the cost of a service call.

Followed the instructions in the video, which showed our exact refrigerator. Very easy instruction, for a simple job. However, it did not fix the problem. At this point I suspect a faulty replacement part (which cannot now return), or some other issue requiring further analysis. Could also be that the original Inlet Water Valve is not at fault, which means that this high probability fix (70%) was not needed.

Ordered part came in 3 days. Removed plug and rear cover. Pulled off old fan . Installed new fan by pushing it on to shaft. Plugged unit back in to check operation, installed rear cover. Done. Part fit perfect. Thanks to this site you folks are great !
