TPX24BRBGBB General Electric Refrigerator - Instructions

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

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.

Use small putty knife to cut internal sealant on ice maker door trim piece. Then you can easily remove it.

Remove front cover did not remove wires remove ice and water unit took off flapper put new one on 5 minutes back together

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!

Separately (from a different site) purchased new compressor fan and motor. I purchased the grommets here because the other site listed the grommets as temporarily out of stock. I did watch one of the videos on PartSelect about the grommet replacement. Repair was pretty simple, biggest challenge was getting to the screw on the far side of the motor. Removed the two screws holding the fan motor into place. Removed motor and blade. Reinstalled with new fan blade, new grommet and new motor.

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.

removed the dispenser and disasembled it repaced plate and reasembled.

1. Use skewer to press plastic tabs under control panel, 2. Remove control panel and unplug solenoid, 3. Unscrew dispenser assembly and solenoid screws, 4. Press in tabs on lamp and remove assembly - unplug, 5. Replace lamp assembly, 6. Replace solenoid assembly and fasten screws, 7. Replace flapper. 8. Replace other parts in reverse order.

unplug refrigerator. Remove Ice bin then remove the cover off the ice maker,(slides off from bottom then lift off top) no reason to remove ice maker completely. Remove center gear screw and remove main gear from Ejector blade. remove (3) screws holding the front plate. The motor and switches are attached to this plate from behind, do not remove the nut from the from the stud that adjusts the travel for the motor. The Motor and switches will come upt with the plate and the shut off arm will come out of a hole in the top right. Its ok just be careful when you put it back to get it in the hole. remove the old cam and replace it wint the new one and reassemble. Its a bit tricky to get all of the microswitches over the new cam just carefully wiggle the plate and cam and don't push too hard. once everything is lined up it should go back together and you can replace the screws and main gear :)

Look at various pertenant DYI articles and videos on the internet. Replaced water filter with bypass plug. Checked water flow to icemaker water solenoid. Ran icemaker diagnostic test which failed. Ordered replacement. On receipt of replacement, began replacement work. To wit: Pulled fiidge from wall and unplugged. (Not necessary to shut water off.) Removed small freezer basket. Unloaded main freezer basket, removed it then removed the freezer door. (A screw on each side bolts the door rail of the chassis slide to the freezer chassis slide.) Loosened screws on rear, top of partition between icemaker and small freezer basket. Pushed up on partition front and popped out U-bar supporting partition bottom being carefull not to bend it. Removed same. Removed screws from partition and set aside. Removed grilled "thingy" between rear of icemaker and partition. Now have access to icemaker screws. Loosened the screws, pushed up and out and carefully let it hang by it's connector. Fiddled with the connector locking tabs and finally got it loose. Compared old and new icemaker. Have to keep the old water funnel. The new wiring harness was stiff and the connector had a different orientation. Twisted both the wiring harness and connector to align connector while the icemaker hung by it's cable being careful not to let the icemaer slip and fall to the bottom. After much fiddling, got the connector inserted and locked. Set icemaker over the two screws, pulled it down and tightend the screws. Put the old funnel into the new unit being very careful to get it right the first time. Put grilled "thingy and the partition and U-bar back in, put door back on, put the ice cube bin back, freezer drawers bac and reloaded the frozen food, plugged fridge in. Done! Time to replace icemaker was about 20 minutes and another 2 hours to do the rest ofthe work. Still required only a nutdriver and phillips.

Unplug your refrigerator. Remove the shelves, light bulb shield and light bulb. Remove the two hex head screws to either side of the light bulb. Wiggle out the back panel. Locate the heater assembly hanging from the bottom of the coils secured with two screws. Remove both screws and lower out the heater. Unclip both connectors from either end of the heater. Take the new heater and replace both end clips. It only goes in one way, so you can't mix them up. Using the two screws, attach the new heater exactly like the original. Wiggle the back panel into place and replace the two hex screws. Put the light bulb and shield back in place and put back in the shelves. You are done.

Easy

The video to replace the flapper looks easy, howerer the first step is to remove thestic cover of the icemaker. In my refrigerator model (as oposed to teh one shown n teh video) teh coved if firmly attached and goes under the refrigerator external plate so I was never abel to take it oot (so step 1 failed).
I was able to replace the flapper TROUGH the whole whre te ice comes from! this took lots of patients and someone with small hands!

I had no idea how to get the parts easily so i search on web , saw parts select.com,i read main folio of the site.which seems to me very reasonable.just one call and they delivered the part.nicely advised me if i need technical support to fix it but i was too confident and i did it.
