CST25GRBEAA Hotpoint Refrigerator - Instructions

I received my parts in 2 days, that is fast. It took me less than 15 minutes to install the unit. Now I've got ice and water from my refrigerator. Instead of taking expensive warranties, I would rather order parts from your company and do it myself on all my appliances.

The only difficult part was not knowing which parts had to be removed to gain access to the flapper to replace it. It appeared as if the frame around the control panel would have to be removed as well as the door handle; we tried but were not able to remove the frame. It turned out that the panel just popped out with the frame in place. Once we had access to the flapper, it was easy to replace it. The repair fixed the problem.

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.

It seems my refrigerator was old enough [1987] that the spacing on the holes for the bracket were different than the part that is currently sold. The holes on the new bracket were 30 mm apart on center, but on the old bracket they were 20 mm apart on center.

Clamped the old and new brackets together in a vise to use the old bracket for spacing and drilled a new hole through the 4mm of steel.

After which it was a snap installing the new hinge assembly.

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!

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.

This should have been an extremely easy, quick job, but because I'm not that familiar with refrigerator parts, and NO INSTRUCTIONS came with the part, it took quite a while. The fittings for the water lines to icemaker and water outlet were dramatically different from the old part. The old part had screw-on fittings. The new one did not. I went first to Ace hardware-they had never seen fitting like this, and didn't know what to tell me. I drove 20 minutes to Home Depot, and the guy there told me that, rather then screwing on, or needing another part, the fittings were a quick connect, where you just shove the plastic tubing into the fitting. Finally an answer!

I went home, did as he'd said, hooked it up (shoved the tubing in, used the provided electrical adapters for the contacts, and screwed the thing on. It takes a good while for the icemaker to get cold enough to start it's cycle (which I found out from an internet search), and about 6 hours later, I started getting ice. It works fine now, love the in the door water/ice on my "new" 10-12 year old $75 plus $35 for the part-huge 26.6 side by side refrigerator, but the part should have had at least an indication that the water fittings just needed to have the tubing shoved into them.

I just followed the instructions on the video and it was exactly as they said......no surprises.

Turned the wire protector to the side. Turned out the old bulb and replaced it with the new. Turned the wire protector back in place and I'm like new.

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

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

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

Opened, discovered not flapper but more complicated

Really simple, I used a can of soup and a small piece of wood set under the door, and tapped it tight with the hammer to hold it in place while I removed the hinge. Two bolts at the bottom and two under the door itself. Installed the new hinge set, bolted tight and removed the shim.
The whole thing took less than 5 minutes
