RR18F1 Gibson Freezer - Instructions

After testing and eliminating the temperature control and the timer as the problem, I turned to the thermostat. I had to wait for the ice buildup to thaw and then could remove the rear freezer panel (this was the 3rd time: first, to discover the ice buildup causing the problem, second when it came back after a complete thaw and test the thermostat, and this time to put the Partselect thermostat back in). My thermostat was visibly damaged from water melting into ice and expanding the casing and eventually breaking one of the connections. I connected the thermostat connection wires (not recommended) to get by while ordering the part, which shipped faster than local repair places could get it from their warehouses, and at a fraction of the cost. I'm really impressed with partselect's fast service and all the knowledgable customers who have explained how they installed them. I now have an intimate knowledge of how my fridge works and saved hundreds in repair, or twice that in replacement. Thanks!

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem

I had to tap the screw holes with a 8/32 tap so that the screws would not bind.

Loosened the screws, removed the old gasket. Cleaned contact area and installed the new gasket. Adjusted the door hinge and used a hair dryer to let the new gasket relax and seal.

I followed the You-Tube instructions, removed the ice from the compressor and replaced the thermostat with the part I received from Part Select. What I took out was a part that was very much inferior to the replacement part. The repair saved me a lot of money for a new freezer and it was not difficult to do following the video. Now the freezer runs better and quieter than ever. Thank you Parts Select.

Replace thermostat and show and tell made it easy.

just like the video show sa 1,2,3 yeaaa thanks

Took out three shelves. Removed 9 screws with a battery powered drill with a phillip screwdriver bit. Popped off the thermostat like I had seen on the video. Put the new thermostat on. Replaced the two wires one at a time. Reassembled the unit. This was so quick that my wife told me to let her know when I wanted to fix the freezer. She was shocked that I had completed the job. I'd been in the garage less than 10 minutes. It has been six weeks. and the freezer is working perfectly.

Removed 2 screws holding front bottom vent grille. . Through opening behind grille found broken part of switch hanging on wires. Removed wires from switch and fed them out through hole for mounting switch, connected wire and pushed into place. The greatest difficulty encountered was my 82 year old knees.

Followed the sites instructions. Empty the bottom part of the freezer. Remove the screws. Move the panel out of the way. Easily remove the old part and replace with the new. Put the panel and screws back in place. The freezer works.

I ordered a new thermostat and installed it in less than 15 minutes. Looks like the problem is fixed. Now ,the freezer cycles on and off correctly. The part was ordered on a Monday and I got it the next day. I am very satisfied.

Unplug freezer let stand all night to defrost. Remove the tray cover which is located on the upper back area inside the freezer.( 3 twist fittings remove it ). Remove the upper stainless steel panel which is secured with 6 screws. This will drop down exposing the condenser. Note all the wires and fan will stay attached to the stainless steel panel, this panel will drop down no need to unplug anything. On the left upper side next to the condenser you will see the thermostat. Two color coded wires. Remove the thermostat and install the new one at the same location.

I unscrewed the screws that held the old fan on, disconnected the wiring harness and removed the old fan. I pulled the blades off the motor and put it on the new fan. One thing of note, the screw holes on the new fan weren't threaded. I assume this is by design, so I used the screws to thread the holes before installing it in the freezer. Once I did this, the rest of the installation was easy, just screw it back in and connect the wiring harness.

Removed bottom cover , just two screws , slid old part through install hole and removed wires from old switch and installed on new switch. Installed new switch in same hole and pushed gently until it locked in place. Reinstalled bottom cover and done.

replace thermostat and timer after defrosting and cleaning out freezer. I took less than 10 minutes and now freezer has a defrost cycle that eliminates frost buildup on the coils.
