FFU14F7HWB Frigidaire Freezer - Instructions

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

Replaced fan. I ordered the fan and received it the following.(-:

When i found out there was no thread in brace where bolts were supposed to screw in, I panicked. I thought I would have to send part back or go to a machine shop to make a thread. I called a friend for help and he told me the bolts would make the thread if I just screwed them in. Sure enough, the bolts made the thread and then I just proceeded to instal motor and put refrigerator back together. It was simple.

Replaced freezer defrost thermostat. Unit worked perfectly.

Watched video on Part Select which shows you how to replace the thermostat with several good pointers. Very easily done and now the freezer works great.

Removed controll with srew driver plug in new conrol

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 three screws each side to remove old slides. Needed spacers under new slide so that drawer would stay on track. Cut old slide to make spacers and installed both slides in 15 mins.

Remove the cover panel inside the freezer, remove and replace the fan motor (pull fan blades off old motor and push on the new one) and replace the cover.

Pulled freezer out from where located to allow shelves to be removed.Unplugged unit, removed shelves and evaporator cover, installed new fan motor. Plugged unit up to check fan motor operation. Reassembled unit, installed shelves and moved freezer back into original location.

Unplugged freezer from electrical socket. Removed lower trays from freezer. Removed sound proof stripping from sides of back panel. Removed upper, lower and side screws from back, lower panel using No. 2 phillips screwdriver. Disconnected motor wires from quick disconnect power supply. Removed motor bracket from freezer back using nut driver. Removed motor from bracket using same nut driver. Replaced motor and screws in bracket. reattached quick disconnect. Attached fan blade to motor making certain to push blade on shaft securely. Replaced bracket to freezer back. Replaced back cover. Replaced stripping. Plugged into power supply. Total time 15-20 minutes.

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.

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.

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.

Pulled the freezer out and unscrewed the screws around door. Gasket slide right out. After placing the new gasket, I used a hair dryer and sealed the gasket tighter. Works like a charm!! Very pleased with this do-it-yourself fix.
